| Maai | my third attempt at GIMP. after living a little... i found it brilliant!\ |
| Maai | need to reboot. Pi3 ran YouTube small screen, 3 terminals and was struggling playback. reboot will clear it |
| doub | is there a way to monitor the supply voltage on a pi zero or do i need some external tool? |
| ShorTie | external tool |
| Maai | doub: PROBES!!! |
| Maai | search for VOLT METER |
| Foxfir3 | how do I start i3 from lightdm? |
| Maai | on the pi board are two points to hold red and a black lead |
| Maai | ACTION a red and a black lead |
| doub | the problem happens after several minutes, so i'd like to not only measure voltage but find a data logger of some kind |
| doub | it would have been easier if the SoC measured supply voltage :-( |
| ShorTie | what problems ?? |
| ShorTie | have you looked in the logs ?? |
| k_sze[work] | Does anybody have recommended settings for exporting video from Adobe Premiere Pro so it can be played on the Raspberry Pi 3 with omxplayer? |
| k_sze[work] | It looks like omxplayer is quite picky about the H.264 profile and level. |
| puff | Evening all. |
| noregret | what can I get along with the noir camera for recording at night? |
| {HD} | Why is it so difficult to delete pi as a user? |
| {HD} | noregret: I bought some I are LED spotlights from eBay that mount to the side of the camera module. I like them pretty well. |
| {HD} | I are = IR |
| {HD} | STUPID spell check |
| noregret | {HD}: can you link me please and how powerful are they? how many meters can they cover |
| Foxfir3 | did the 7" screen rotation get updated in Raspian? |
| azy | whats the best camera i can stick on this thing? |
| Foxfir3 | 7" screen show boot, but then goes blank. is that a common issue? |
| Foxfir3 | when i plugin the hdmi while its running It show the 7" screen setting. I installed Arandr and checked again. shutdown, pulled out the hdmi, and booted. Same thing. |
| NotInTheMood | Anyone running a RPI 3 as a wireless AP using the built in wifi? I'm wondering about how the range is. If anyone is or has something to say about it please highlight me |
| Foxfir3 | solved. screensaver cuts in too soon. |
| Habbie | NotInTheMood, i do that on occasion but over just 2 meters - it works well in that case |
| Habbie | Foxfir3, re 'reboot without battery' - did you figure out that question? |
| NotInTheMood | Habbie, whats the max range you've gotten it to go? Also how many clients? I'm looking at 3 clients, youtube / general bullshit |
| Foxfir3 | Habbie: actually I didnt. I just dont enough about hardware yet I guess. I dont see any battery on the Pi3. So I wonder how It is possible. But maybe the reboot only goes down to certain run level. Sorry. so much to learn :D |
| Habbie | NotInTheMood, two clients, 2 meters, that's all i tested |
| Habbie | Foxfir3, so here's the thing - why do you think you need a battery to be able to reboot? |
| Foxfir3 | Habbie: right. hmm.. I thought a battery in a computer was there to boot the first level. So obviously I was wrong. |
| Habbie | Foxfir3, ack, it's not |
| Foxfir3 | Habbie: so the battery only keeps track of time? |
| Habbie | Foxfir3, what a battery does depends on the system; on some, it's just for time, on others, it also keeps various settings ('BIOS/CMOS settings') |
| Foxfir3 | Habbie: thanks :) learned something new today then. |
| password16 | this is the firstime in my life i typed the correct channel name the first time for this channel |
| Lartza | Depends if you were looking for raspberry pis or pies |
| shauno | trying to pluralize pi still boggles my mind |
| Lartza | I pledge non-nativity if I did it wrong :D |
| shauno | I'd have no idea if you did. if I knew what correct was, there'd be no boggling |
| ShorTie | pi's |
| ShorTie | isn't that how you do names ?? |
| Habbie | ShorTie, no, that's how you do possessive |
| Lartza | someone toll all of pi's pies |
| Lartza | *stole all |
| Lartza | the rest of the pis were very upset of the pie's fate |
| password16 | our pi's came in a pie box from the pifactory |
| password16 | we kept the box because of the excellent pun |
| azy | whats the best camera i can stick on a raspberry pi? |
| ScrumpyJack | i have the google audio hat on a rpi3 (no AIY software installed yet) |
| ScrumpyJack | the big button is connected to gpio 23 |
| ScrumpyJack | how do i "press the button" with wirigpi? |
| ScrumpyJack | gpio write 23 1 doesn't "stick" |
| ScrumpyJack | ok, it seems GPIO23 is wiringpi pin 4 |
| Habbie | ScrumpyJack, wiringpi has flags to tell it what kind of numbering you mean |
| gordonDrogon | maybe you need to read the big button? |
| gordonDrogon | got a link to the google audio hat? |
| gordonDrogon | oh wait - I'll google it ;-) |
| gordonDrogon | try this: |
| gordonDrogon | gpio -g mode 23 in ; gpio -g mode 23 up |
| gordonDrogon | then: while true; do echo -n "`gpio -g read 23`" ; done |
| gordonDrogon | or maybe you're wanting to simulate the button push via software? that might be possible, but it will depend on the circuit which I've not seen. |
| gordonDrogon | ScrumpyJack, ping? |
| ScrumpyJack | gordonDrogon: just off to lunch, biab |
| lastaid | smsc95xx: unknown parameter 'macaddr' ignored ... this is what i am getting with debian aarch64 on the raspberry pi. also the network interface never comes online |
| gordonDrogon | smsc95xx is the network interface. |
| lastaid | yes |
| lastaid | can i set the "parameter" somewhere in the bootconfig? |
| lastaid | i think the problem is that i cannot read the cpuid (serial) which is probably used to set the mac addr |
| lastaid | when i do a cat /proc/cpuinfo i don't get the serial either |
| gordonDrogon | no idea... but if this were raspbian ... |
| gordonDrogon | maybe check the cmdline.txt file on a raspbian install vs. this debian system... |
| lastaid | gordonDrogon: the debian one has to do tons more. but i am acutally interested if i can inject my own "macaddr" into the kernel using cmdline.txt |
| gordonDrogon | the ethernet mac address is normally set from the serial number. you can change it once booted - normally. |
| hypercore | which os should i install on my v3? (not raspbarian) |
| shiftplusone | iirc, the mac address is passed to the kernel by the firmware, but uboot drops that information. |
| shiftplusone | hypercore: raspbian or archlinux. |
| hypercore | is ubuntu not a good choice? |
| shiftplusone | or whatever else you want, there's no one OS you 'should' install. |
| shiftplusone | ubuntu would work. |
| Habbie | hypercore, why not raspbian? |
| hypercore | shiftplusone: i use arch as my daily driver, but i think i'll use ubuntu on my pi, as all my VPSs use ubuntu anyway |
| hypercore | Habbie: i don't need a GUI |
| Habbie | hypercore, raspbian lite doesn't have a gui |
| hypercore | didn't realize there was a lite version |
| hypercore | Habbie: are you recommending raspbarian lite? |
| Habbie | i am not recommending anything |
| Habbie | i am trying to help you figure out what is best |
| Habbie | but i like raspbian lite a lot |
| hypercore | Habbie: why use raspbian lite over debian/ubuntu lite though? |
| Habbie | hypercore, i just said i am not recommending anything |
| shiftplusone | raspbian has the most support |
| hypercore | shiftplusone: for the rasp pi hardware you mean? |
| shiftplusone | from community and for the hardware |
| hypercore | shiftplusone: what do you mean by "from community"? |
| shiftplusone | most people run raspbian. If you run into trouble, it's easy to get help. |
| shiftplusone | If you run ubuntu, chances are most people will ignore your question because they don't run it themselves. |
| hypercore | shiftplusone: meh, that's ok. Can't think of many situations where i would need help anyway |
| hypercore | think i'll go with ubuntu core |
| shiftplusone | isn't ubuntu core some iot thing that's not ubuntu? |
| Habbie | yeah, no apt-get |
| Habbie | just snappy |
| hypercore | ah in that case ubuntu-server |
| hypercore | how big is raspbarian lite? |
| shiftplusone | if they provide a pi image. |
| shiftplusone | I know ubuntu mate do, but you said you don't want a gui |
| hypercore | yeah a gui would just be a waste of space, i wouldn't use it |
| hypercore | raspbarian lite is 350MB apparently |
| shiftplusone | that might be the compressed size |
| hypercore | guess i'll give raspbarian lite a shot then |
| Habbie | raspbian |
| Habbie | not raspbarian |
| Syliss | lol |
| mk-fg | ACTION read that as rasbarbarian |
| Netham45 | Can I get a 120Hz signal from the PWM pins on an RPi? |
| Habbie | Netham45, i bet |
| Netham45 | The 'channel' for RPI.GPIO is the same as the pin, right? Or is there another mapping? |
| Habbie | i don't know |
| Habbie | got docs? |
| waveform | Netham45, depends on RPi.GPIO.setmode which is called with either BOARD (pin numbering) or BCM (GPIO numbering) |
| Netham45 | Okay. The code I copied without really reading at all is using BCM. I'm assuming those are the GPIO numbers next to the pinout. |
| Habbie | https://pinout.xyz/ |
| Habbie | shows you board and BCM |
| hypercore | how do i ssh into my rasbpi? |
| Habbie | did you enable ssh? |
| hypercore | i haven't accessed the device at all, that's what im trying to do |
| hypercore | is ssh not enabled by default? |
| Habbie | it's not |
| Habbie | for security reasons |
| Habbie | you can put a file called 'ssh' on the FAT partition before you stick the SD in the Pi |
| Habbie | or, if you have a screen and a keyboard, configure it when booted |
| hypercore | Habbie: can i use screen/keyboard with raspbarian lite? |
| Habbie | yes |
| hypercore | Habbie: thanks. OK so i've enabled ssh, but i'm not sure i can access my wlan |
| Habbie | hypercore, the pi is not wired? |
| hypercore | Habbie: i've put in the ESSID and the passphrase, but apt-get update fails (due to no internet connection most likely) |
| Habbie | where did you put it in? |
| hypercore | Habbie: i attached a keyboard and monitor to it |
| hypercore | it's not using a cat cable atm |
| hypercore | i just have my wireless dongle in it |
| {HD} | Why can’t I start “raspberry pi configuration“ from an XRDP session? |
| akk | hypercore: ifconfig or ip link can show you whether your network is up, and iwconfig can show if you're connected to wifi. |
| Lartza | akk, iw |
| akk | Maybe that too. I haven't used iw and the usage is very long and not super helpful. |
| Lartza | akk, ifconfig and iwconfig are deprecated, replaced by ip and iw |
| akk | Oh, figures. Well, I offered commands hypercore could actually type, feel free to chime in with the comparable iw command |
| akk | because it's not obvious to me from a quick read of the 101 lines of usage I get if I just type iw. |
| hypercore | got it working! |
| Lartza | akk, iw dev wlan0 link afaict |
| Lartza | not sure if just iw link or iw dev link works too, for all devices |
| akk | I get "command failed: No such device (-19)" for iw dev wlan0 link on a regular debian box (don't have a pi up atm) but maybe that's because the wlan0 link isn't active. |
| akk | Without the "dev" it gives the long usage statement. |
| hypercore | what do i do with my pi now? |
| H4ndy | stuff! |
| Netham45 | Cool. Got an LED controlling a 120v phototransistor and I can use PWM to dim an LED bulb with it. :D |
| Netham45 | I'd record a video but apparently it's impossible to record a video of a bulb dimming on a Pixel |
| hypercore | anyone here? |
| KevinCarbonara | maybe |
| hypercore | hi! just wondering if someone could help me create a docker-compose file, i'm a little unsure of how to do it for this particular example |
| KevinCarbonara | sorry, I'm not experienced with docker |
| zleap | KevinCarbonara: you could try #docker |
| KevinCarbonara | :| |
| zleap | if no one here can help |
| zleap | i don't know much about docker either, i did see a kubernates set up on Saturday but it wasn't on, it was on 3x raspberry pi cluster. hopefully will see a demo at a future exeter pi jam |
| mpli | when I use iwlist wlan0 scan on a fresh raspbian I only get displayed connection speeds up to 54 Mb/s, but iwconfig lists a higher connection speed for my currently connected network. Is that normal? |
| Greg-J | What chip does rpi3 use for 3.5mm audio output? |
| Habbie | Greg-J, there's not really a DAC on it, if that's what you are asking |
| shiftplusone | it's just filtered PWM |
| Greg-J | Huh. |
| Greg-J | Is it just using pin(s) straight off the BCM2837 to the jack? Is there nothing that lies between? |
| Habbie | Greg-J, https://www.raspberrypi.org/forums/viewtopic.php?t=127585 has some nice details |
| Greg-J | Cheers for that |
| shiftplusone | there's a filter |
| zleap | mpli: what is the speed of your wireless connection on the router] |
| Habbie | the url has a diagram of the filter |
| zleap | i am guessing if that is set to 54Mb/s then anything connected will only go that high |
| zleap | hi r00ter |
| zleap | sorry r3 |
| Greg-J | Thanks Habbie |
| Habbie | np |
| r3 | sorry? I'm sorry for the quit/joins |
| Greg-J | This isn't bad at all. I thought I was going to have to add a DAC to this CM3 project. |
| Habbie | Greg-J, note that on the pi1 the quality was terrible |
| Habbie | Greg-J, i hear pi2 and up do slightly better |
| Habbie | Greg-J, but be prepared for disappointment |
| Greg-J | Roger that |
| Habbie | i'm guessing cm3 comes without the filter? |
| Greg-J | I think so. There is no mention of analog audio on the pinout. |
| mpli | the networks I can find here support up to ac |
| mpli | n is as well supported, so I should at least detect those datarates |
| Habbie | Greg-J, but the two pins are there? |
| Greg-J | Yeah, the pins are all there (and more) |
| Habbie | good |
| Greg-J | The word "audio" isn't even mentioned in the datasheet. |
| mpli | but iwlist is only telling me about datarates up to 54mbit, even though the networks support more and I'm connected with a faster speed |
| mpli | I don't understand why it is not displaying the faster speeds |
| Greg-J | I really ought to write an article when I'm done with this on what you need to add to the CM3 to get basic functionality. I haven't really found a lot of good material on it yet. |
| Habbie | Greg-J, isn't a single CM3 way expensive to get working anyway? |
| Habbie | Greg-J, or are you doing a bigger project? |
| shauno | I think most people just crib off the cmio schematics where needed |
| Greg-J | To get it "working" is pretty much just power supply 1.8/3.3/5 and running usb+hdmi. |
| Greg-J | It's not too bad. |
| ali1234 | shiftplusone: when did libraspberrypi-dev get pkgconfigs? |
| ali1234 | https://bugzilla.gnome.org/show_bug.cgi?id=770987#c12 |
| Greg-J | shauno, I can't read schematics without reference yet. |
| Greg-J | This is a hobby I'm really _just_ getting into. |
| shauno | I do wish there were some cheaper boards for the CM though. I have a spare CM1, but it's not worth spending €100 on a cmio for |
| akk | Is there a name for the USB B male to B male cable I'd need to use a USB console on a pi3b? |
| akk | I'm searching ebay for things like usb b male to b male but it's finding everything else but. |
| Habbie | the only B port on the pi3 is the microusb for power |
| Habbie | where did you read that something like this is possible? |
| akk | I've done it with a pi0 -- google for raspberry pi ethernet gadget. It's very useful. |
| Habbie | yes |
| Habbie | i've also done it with a pi0 |
| shauno | that's quite specific to the zero (and the model A, I believe, but haven't tried) |
| akk | Oh, really? Darn. |
| akk | pwillard mentioned it the other day on arduino and I thought maybe it was universal if I could just find the right cable. |
| shauno | it won't work with a hub between the cpu & the host, and the model B uses a hub to give you four ports (and ethernet) |
| akk | I do have a 1A so the cable would still be useful for that (it also has B-sized USB plugs, like the model B) but I don't use the A much. |
| Greg-J | shauno, Are CM_VBAT and CM_VDAC both 5v? |
| Habbie | akk, 'B-sized USB plugs'? do you have a picture of what you mean? |
| akk | Oh, maybe I mean A. I thought B was the standard-size USB but it looks like I had that wrong. |
| Habbie | A and B are not sizes |
| Habbie | A and B are sides |
| akk | Really? I guess the wikipedia page is very misleading and I should be looking elsewhere. |
| Habbie | https://en.wikipedia.org/wiki/USB ? |
| akk | Yes, or specifically https://en.wikipedia.org/wiki/Usb#Host_and_device_interface_receptacles |
| akk | which seems pretty clear that type-A is the size I'm talking about (so I erred saying B) but that it's a size, not an end. |
| Habbie | i don't see how you would conclude that |
| Habbie | it has mini-a, mini-b, etc. |
| Greg-J | Ahhh, okay. VBAT is 5V and VDAC is 2.5V |
| shauno | it's kinda .. both. A is the host, B is the device. they put a different plug on each end to enforce this. then went nuts creating different sizes every few years when we started using it for more than just printers |
| akk | It does, but type-A, there in the upper left, is the standard plug I was talking about |
| akk | whether male or female |
| Habbie | akk, because there was no size prefix in the days there was just one size |
| akk | I have cables that go from that connector male to that connector female ("usb extension cable") |
| akk | but not with that size male on both ends |
| Habbie | i actually do have one |
| Habbie | it does serial on one of the early pi copycat boards |
| Habbie | forgot the name |
| akk | Ironically, we did have one such cable here but when we were cleaning up the house about 6 months ago, I said "Nothing ever uses that, why do we even have it?" and I guess we got rid of it. |
| shauno | A to A is an evil cable that's not meant to exist lol |
| Habbie | shauno, +1 |
| akk | Oh, well, if it would only work on my Pi 1A I guess I don't care enough to order a cable anyway. |
| shauno | it's supposed to be (size-)A on the host to (size-)B on device. Then they came up with OTG to confuse the issue, and usb-c to give up on the issue |
| Habbie | at least otg is kind of explicit about it |
| akk | I think the A-male-to-A-male cable we had was for some ancient Mac thing. |
| shauno | I still think otg is witchcraft |
| Habbie | oh me too |
| Habbie | my wife deals with otg all day and even she still thinks it's weird |
| shauno | and then usb-c is what happens when the witches form committees |
| akk | I only know about OTG because I ordered some adapters when I got my first 0w. |
| Habbie | akk, you can also use those adapters to attach a mouse to your phone |
| akk | And the adapters turned out to be useful for making a power cable for the 0w. |
| akk | Habbie: That sounds pretty cool -- I should try that sometime. |
| Habbie | so i tried powering the 0w from my chromebook while also doing otg serial |
| Habbie | started smelling bad pretty quickly |
| Habbie | and then the port was dead until i powercycled the chromebook |
| Habbie | so don't do that, kids |
| shauno | I've never needed to do that? the 0 will power from the otg port |
| Habbie | shauno, apparently the chromebook was not willing to provide enough oomph thre |
| Habbie | there |
| shauno | that's a shame. that's how I almost always use mine. just a bog standard "cable I'd charge my phone with" from the laptop to the zero, and nothing else |
| Habbie | uhuh |
| Habbie | works fine with the wemos d1 mini |
| Habbie | but not with the official nodemcu board |
| akk | Habbie: Too cool! (just tried mouse on android) |
| Habbie | and not the 0w |
| Habbie | don't know about the 0 non-w |
| Habbie | some of these things got better when i bought a bunch of Anker cables instead of a cheap set i got somewhere |
| Habbie | but not all of it |
| shauno | weird. wonder if the chromebook is being fussy about things negotiating for power properly |
| Habbie | possibly |
| Habbie | i decided not to experiment further :) |
| Habbie | meanwhile my pi3 gives me the yellow voltage icon if i attach a single wemos d1 mini |
| shauno | I know the macs just resorted to making 2100mA available everywhere, when the first ipads wouldn't charge from 500mA |
| Habbie | you'd think ipads could negotiate correctly with macs |
| shauno | you'd think. round about that time there was 3 or 4 different 'standards' for identifying a device as high-current |
| Habbie | ack |
| Greg-J | Does anyone know of a chip+antenna package like the ESP-WROOM-32 that is raspberry-pi friendly but isn't so thick? |
| Habbie | Greg-J, dumb question, doesn't the cm3 have wifi? |
| MacGeek | I don't think it does |
| shauno | nope |
| Habbie | ah |
| Habbie | i think wemos has esp8266 boards without the big plate now |
| shauno | it's pretty much just the soc, ram, and flash (emmc) |
| Habbie | shauno, so more like a pi2 1.2 than a 3 |
| Greg-J | No Habbie |
| Greg-J | No connectivity |
| shauno | like a CM with a shiny new cpu :) |
| Habbie | ack :) |
| shauno | exactly what I wanted to be honest. only catch was they had to slightly change some of the voltage requirements |
| cerion | hi. I have a headless rpi0 W on an old phone charger. I wonder if it runs underpowered. Is there any way to know that ? by looking at the log, or some /proc or /sys file ? |
| gordonDrogon | the logs might say. |
| gordonDrogon | try just typing dmesg into it. |
| gordonDrogon | if you have a screen attached you'll see a yellow lightening bolt icon if the voltage is too low. |
| cerion | gordonDrogon: at what kind of message am I looking for ? |
| cerion | gordonDrogon: no screen |
| gordonDrogon | I can't remember - it's been some time since I saw it, but I recall it was obvious. |
| Lartza | cerion, multimeter? |
| cerion | Lartza: no. |
| gordonDrogon | oh, hang on ... |
| gordonDrogon | I'm not sure if the Zero has the low voltage detection chip fitted... |
| gordonDrogon | and google isn't help me here here - yet. |
| cerion | gordonDrogon: ok |
| gordonDrogon | cerion, issues to do with low voltae include general instability and possible SD card write errors. |
| gordonDrogon | the zero is fairly low consumption to the others though, so should work better with a PSU that might not power a v3 OK. |
| Lartza | I noticed it by my filesystem getting slowly corrupted |
| Lartza | headless pi2 |
| gordonDrogon | did a better psu fix it? |
| Lartza | took a while for it to corrupt something I noticed though :/ |
| Lartza | Yes, or the switch from f2fs to ext4, I believe both |
| Lartza | f2fs has been fine for me on desktop systems and phones so |
| cerion | Lartza: did you switch after or before the corruption ? I tried to use f2fs but I kept on getting error message about non clean fsck so I gave up |
| Lartza | after |
| Lartza | f2fs isn't really clear cut faster either so, it's not really worth the effort most of the time |
| Lartza | it's slower for stuff like sqlite databases iirc |
| cerion | with ext4, an unclean shutdown is dealt with an automatic fsck at the next boot. with f2fs, that did worked |
| cerion | +not+ |
| Lartza | I usually fsckd my f2fs filesystem on a virtual machine |
| Lartza | manually |
| Lartza | But that might just be an Arch thing plus pebkac for fsck on boot not working |
| linux_dream | hi people, quick question. on amazon i see several sellers for the rpi3. apparently some of them ship the made in china rpi3. is it exactly the same as the official one from great britain? |
| redrabbit | doesnt really matter |
| redrabbit | so, yes |
| linux_dream | why? i thought the rpi was expensive because of charity. if i buy the one from china, will part of my money go to charity |
| redrabbit | its the other way around. |
| redrabbit | because of charity its supposed to be not expensive |
| linux_dream | if not, then why would i go for a rpi3 instead of say, an orange pi. if both are from china and none contributes to charity, I should pick the cheaper |
| redrabbit | they are fine |
| redrabbit | i have both |
| redrabbit | still prefer the rpi for software support |
| linux_dream | you cannot install raspbian on an orange pi? |
| redrabbit | no |
| razzy | anyone tried nixos? |
| redrabbit | i use armbian |
| linux_dream | oh i didnt know that redrabbit . |
| redrabbit | raspbian is rpi only |
| linux_dream | i see |
| linux_dream | and should i get one of those kits for the rpi, that includes some stuff, or should i buy them separately ? what bothers me is the shipping price, adding up enormously if i ship separately |
| redrabbit | separately |
| redrabbit | aliexpress has free shipping |
| linux_dream | yeah right but they are made in china, and they aren't recommended on the rpi official website. so i was wondering whether the money goes to charity like if i buy the one from GB |
| redrabbit | kits are rarely worth it |
| redrabbit | ive never seen a good one |
| redrabbit | its the same |
| linux_dream | so the money goes to the rpi foundation? |
| akk | We have some people in the makerspace starting with kits and they seem to be doing okay, but I think you'll hit their limitations fairly quickly. |
| akk | The RPi kits mostly don't seem to have the extensive hardware collection you see in arduino kits. |
| linux_dream | https://www.amazon.fr/Globmall-Raspberry-Starter-Sup%C3%A9rieur-Alimentation/dp/B073S56VKC/ref=sr_1_7?s=computers&ie=UTF8&qid=1518129637&sr=1-7&keywords=raspberry+pi+3 |
| razzy | redrabbit: what do you think about beaglebone? |
| razzy | why raspberry use closed graphics chip? |
| linux_dream | what on earth...... i just googled https://raspberrypi.stackexchange.com/questions/14790/is-it-safe-to-buy-pi-at-ebay-from-china and the claim is that i shouldnt buy the rpi3 from china |
| linux_dream | the money wont go to charity |
| linux_dream | so they're overpriced as hell |
| Lartza | razzy, There's on open alternative? |
| Lartza | The pi also has an open source driver so |
| Lartza | Not sure what more you want open sourced, the firmware? |
| razzy | Lartza: beaglebone is opensource alternative imho |
| linux_dream | ive heard orange pi too |
| redrabbit | razzy: beaglebone is vaporware right |
| redrabbit | where can you order them |
| Lartza | razzy, No video decoding and I doubt the firmware is open? |
| Lartza | linux_dream, Definitely not, even the reverse engineering of Mali is stalled afaik |
| Lartza | I don't think there are even free mali drivers |
| Lartza | *open source |
| Lartza | indeed, there is a work in progress driver based on the earlier reverse engineering, and a binary driver |
| linux_dream | ah ok thanks for the info |
| redrabbit | linux_dream: got my rpi3 from amazon and uk vendors for the rpi0w/rpi0.. aliexpress for the orange pi |
| redrabbit | works fine |
| Lartza | but like I said, what's wrong with rpi? It's open source too |
| redrabbit | nothing |
| Lartza | redrabbit, I can find beaglebones for sale just fine |
| redrabbit | link |
| Lartza | element14, mouser, digikey |
| Lartza | and arrow in the US apparently |
| Lartza | https://www.partco.fi/fi/minitietokoneet/beaglebone/4057-bb-bblk-000.html |
| Lartza | that's my local farnell distributor |
| redrabbit | pricey |
| Lartza | yes? |
| Lartza | the wireless version is even in stock, the regular one is an order item |
| redrabbit | probably mixed up beaglebone with some other arm board |
| redrabbit | that i wanted and could not find |
| Lartza | dragonboard? |
| redrabbit | maybe the chip |
| redrabbit | or something else idk |
| Lartza | or maybe the renegade boards |
| Lartza | they are hard to come by iirc |
| redrabbit | the rpis are fine anyway |
| redrabbit | orange pis as well |
| redrabbit | and cheap |
| Lartza | altho seems now you can actually get them https://www.loverpi.com/collections/libre-computer-project/products/libre-computer-board-roc-rk3328-cc |
| Lartza | or well, preorder ;D |
| redrabbit | LOL |
| Lartza | they were on indiegogo and their target there was january this year so, not that late yet |
| redrabbit | i never backed any crowdfunded stuff never |
| Lartza | I have unfortunately... |
| Lartza | only one of them turned out awesome, and that was divinity original sin 2 |
| redrabbit | i order products |
| shauno | I've mostly had good luck with kickstarter |
| shauno | the main catch is just things taking so long to ship, that by time they arrive I have to try to explain why I thought something was a good idea 9 months ago |
| wyvern | I can't seem to figure out how to use the serial console. I've got a rpi 3 running the latest raspbian, and I can tell it's booted up because it's receiving an IP address from my DHCP server. I have an FTDI USB/serial board (https://www.sparkfun.com/products/9873) plugged in to a https://www.sparkfun.com/products/13717. What should I be doing with minicom to see a console? |
| wyvern | I am getting a tty created at least: `FTDI USB Serial Device converter now attached to ttyUSB0` |
| BurtyB | wyvern, did you enable the uart in config.txt in the boot partition? |
| wyvern | I didn't realize I needed to do that. Is there documentation beyond https://www.raspberrypi.org/documentation/installation/installing-images/README.md ? |
| wyvern | (i'm using the Stretch Lite image; I have no need for a desktop) |
| shauno | you'll probably want to take a peek at the uart docs too; https://www.raspberrypi.org/documentation/configuration/uart.md (it's grown a little complicated because the bluetooth is using the 'good' uart by default) |
| wyvern | I see. How are new users expected to figure this out by themselves? I'm just wondering if I missed something obvious |
| wyvern | having a distro that boots in a "no ssh, no serial console" default seems... odd |
| BurtyB | wyvern, from that doc you just need to add "enable_uart=1" to config.txt and then you should get a console running and connect with 115200 8n1 |
| akk | wyvern: You're not the only one who thinks that. But I guess raspbian is more aimed at people using the desktop with a monitor. |
| wyvern | apparently so, since their other config wouldn't really be less useful if it didn't boot at all ;) |
| wyvern | Is there some other less useless distro that people use in practice, or is raspbian pretty much it |
| akk | And in addition to the enable_uart=1 you'll probably need another line: dtoverlay=pi3-disable-bt |
| BurtyB | akk, you don't need that |
| akk | No? I guess I didn't try it without, but the official docs told me to include that IIRC. |
| akk | wyvern: Also I think the raspbian people figure anyone with the audacity to run headless must be expert enough to be good at googling. |
| wyvern | I did google quite a bit and found lots of people saying "And then I used minicom and everything just worked" :/ |
| akk | Which probably makes some sense since we also need to be able to configure wifi and run ssh. |
| akk | Really? When I googled after discovering it didn't work I found it pretty quickly. |
| wyvern | I found lots of things that were all in the pattern of https://startingelectronics.org/articles/raspberry-PI/serial-port-connecting-linux/ |
| wyvern | "Look it's easy. Just run minicom and it works. Tada!" |
| akk | Oh, maybe the difference is that I knew it was a new change, so I was probably googling for "raspberry pi zero", not just raspberry pi |
| wyvern | Probably. |
| akk | because the console used to work on older pis without doing anything extra. |
| shauno | not that it helps, but if I search for raspberry pi serial console, the first result I get is how to enable it, form adafruit's tutorial |
| wyvern | I found https://learn.adafruit.com/ftdi-friend/com-slash-serial-port-name from adafruit, which was of course unhelpful |
| akk | I seem to have somehow disabled mine (on an install that used to work) so there may be some subtle things in play too. |
| wyvern | Knowing what I know now, I can get some query strings that get more useful results... it just seems pretty vicious to say "here, install this raspbian thing" and not have even a link to "oh and you'll need this to make it work at all" |
| akk | I can't figure out what I did that disabled it. |
| wyvern | oh well |
| akk | wyvern: I do agree, I wish they were more up front about headless issues. |
| wyvern | do people typically run the desktop distro even if they're going to be using it headless in practice? |
| akk | There is an official page somewhere on enabling the serial console but now I can't seem to find it whatever I search for. |
| akk | wyvern: I don't, I start with raspbian lite and add what I need from there. |
| redrabbit | same |
| wyvern | yeah, all i wanted was the rust compiler toolchain... didn't seem so hard... |
| redrabbit | screen /dev/ttyUSB0 <baudrate> |
| BCMM | wyvern: most linux distros that people actually use are not distinctly "desktop distros" or "server distros" |
| BCMM | so my headless systems usually run distros that also work as desktops |
| wyvern | Yes, but I don't want to have to uninstall a desktop environment and other associated fluff. |
| redrabbit | you dont have to |
| redrabbit | raspbian lite |
| wyvern | Which, in its default config, is useless. |
| redrabbit | or debian... or armbian.. or lots of options |
| wyvern | I'm just sayin' that's weird. |
| redrabbit | whats your point there |
| redrabbit | use what works |
| akk | The point is that it would make more sense to set up raspbian lite so that it had ssh and a serial console to begin with. |
| akk | It's a reasonable point. |
| redrabbit | take a second to set it up |
| wyvern | https://www.raspberrypi.org/downloads/raspbian/ this page, which is there for beginners to read and learn from, does not say "BTW if you download Stretch Lite you will be confused because it doesn't work at all by default" |
| wyvern | It just says "slap that on a SD card and you're good to go" basically |
| wyvern | Which, compared to the otherwise excellent rpi beginner experience, stinks. |
| wyvern | It startled me. That's my point. Nothing more. |
| redrabbit | https://gist.github.com/1rabbit/c7d7bce0e14124145040b350bfedaf32 i made that script that does the config automatically |
| redrabbit | i use it quite often so i dont waste time on that |
| wyvern | oh kayyy... |
| BCMM | i mean, either you start with a distro that doesn't have the stuff you need, and add the stuff you need |
| BCMM | or you start with an image that has stuff you don't need, and remove what you don't need |
| BCMM | it's a mistake to expect there to be a distro that fits your precise use case right out of the box |
| wyvern | Yeah, like "being able to log in" |
| wyvern | pretty weird use case |
| faekjarz | Hi, anyone here, who sucessfully used a HDMI to VGA converter dongle with a Ras Pi 3 B? (Does the Pi 3 B provide power via its HDMI port, in order to drive sich a converter dongle?) |
| faekjarz | …i mean, it's HDMI, and thie pi 3b has hdmi, so it should be compatible, right? |
| mlelstv | it even works |
