dl9pf_leon-anavi: got the link for the flags needed for rpi2  ?14:01
leon-anaviyes, thank you: agl-medium-arm-compiler14:01
dl9pf_And likely GPU_MEM is too high with the newer kernels14:01
leon-anaviok, is there a recommended value?14:02
dl9pf_25514:02
dl9pf_aka <256M as this is the current check in the kernel14:02
dl9pf_for cma14:02
dl9pf_that will go away again, but until then the more apps we start it will lock-up .14:03
leon-anaviok, noted down.14:08

furyok so, i did a repo sync and built the raspberry pi image, i got it booting up and apps are actually opening now...am i supposed to be able to hear sound out the analog output or no?14:35
furyalso, hugs to everyone in manchester :( if you need me to go and stab anybody in the face for you, let me know14:36

smurrayfury: there's some issue atm with the apps not being able to connect to PulseAudio on master15:05
smurrayfury: we're poking around to figure out what's causing it15:05
*** fredw has joined #automotive15:07
furyah. i figured it was trying to output to hdmi or something, so i hooked up an hdmi monitor and some speakers, but no dice. anything i can do to help track it down?15:22
CTtpollardis audiomanager service running?15:23
CTtpollardif AGL is still using it15:23
*** jobol has quit IRC15:26
furyCTtpollard: looks like it, media player app is just not connecting15:27
*** khem has joined #automotive15:32
furyhehe that's pretty neat, i can still connect to it over bluetooth and the media player can get the track info and forward/back controls even tho the audio's coming over the phone15:33
*** jlrmagnus has joined #automotive15:35
smurrayCTtpollard: audiomanager is running, it's something lower level related to permissions15:37
smurrayfury: yes, I've observed that as well15:37
furycool, i just got the media player to crash :D15:47
furyon a rpi3, USB flash drive plugged in with one wav file, paired and connected my iphone and played for a while (albeit with no audio), then disconnected the iphone, media player went back to displaying the track it found on the flash drive, i tried to select it (again knowing i wouldn't hear anything) and it crashed15:48
furyhttps://www.irccloud.com/pastebin/2OCfDbcK/15:48
furylog starts at the bluetooth disconnect15:49
furystarted the media player application and tried again, it crashed again15:49
*** fredw has quit IRC15:57
*** jlrmagnus has quit IRC16:00
smurrayfury: anything that uses PA is borked atm16:09
furymakes sense... was hoping (or not hoping :D) that i found a bug caused by disconnecting bluetooth and trying to play16:10
smurrayfury: that's still possible, but it's hard to say atm16:11
*** jlrmagnus has joined #automotive16:16
*** joone has joined #automotive16:21
*** zeenix has quit IRC16:27
mdpyou can workaround by explicitly starting the PA daemon: "systemctl start --user pulseaudio" before running any apps16:27
mdpit appear socket activation unit is not enabled in latest builds16:28
mdpas smurray mentions, we're sifting through the yuuuge pile of changes since the last known good builds (for me, that was 0512)16:30
*** GillesF has joined #automotive16:43
furymdp: sweet, thanks for the tip! I was fixing to run all the way back to chinook cause I'm not quite sure how to roll the repo back in time like that16:46
*** mpaolino has quit IRC16:52
*** jlrmagnus has quit IRC16:57
*** toscalix has quit IRC16:58
*** fredw has joined #automotive16:59
furyI'm sure y'all have thought of this already, but did upgrading to pulseaudio 9 have anything to do with it? e.g. a bb recipe to enable socket activation that's only set to operate on 817:05
dl9pf_mdp: pulseaudio daemon not being started at all on bootup ?17:07
*** fredw has quit IRC17:07
smurrayfury: the upgrade to PA 9 was back in January17:07
mdpThis is since 051217:07
furyoh, whoops17:07
*** jlrmagnus has joined #automotive17:08
mdpdl9pf_: yup..normally it's socket activated and I double-checked that behavior on my 0512 build as true.17:09
mdpOn a current build I noted that the pulseaudio.socket unit isn't even enabled17:10
mdpSo that's a problem17:10
mranostaymdp: explains my fun last night.. SPEC-61117:13
mdpYeah, we started some debug until you left coasters arrived ;)17:14
mdpI'll paste some info on there17:14
mdpIn*17:14

mdpmranostay: I created spec-612 with some cause information and linked to your specific case in spec-61117:51
mdpmranostay: if you check the log, you should see piles of "Could not initialize supporting library." that errupt from Qt's gstreamer backend and the PA plugin that fails to connect.17:52
dl9pf_hmm , so likely PA recipes changes ?!17:59
smurraydl9pf_: I don't see anything from upstream18:00
furyhomescreen fails to start sometimes... ever seen that?18:00
smurrayfury: yep18:01
smurrayfury: pretty sure there's a JIRA issue for that18:02
furysweet. i ought to check that out some time18:02
furyi keep bringing up stuff y'all already know about :D18:02
smurrayheh, it's all good, definitely need more testers18:02
furywell, i tried the systemctl start --user pulseaudio before running anything, i get some hissing out of my speakers but media player still crashes when i try to play something :o18:03
furythat's pretty cool18:03
furydo i need to do it before or after the home screen starts?18:05
smurrayfury: see https://jira.automotivelinux.org/browse/SPEC-575 , that's likely the same issue18:05
smurrayI imagine just before you start any apps should be fine18:05
furylooks about right - https://pastebin.com/HEHZPfd518:06
furyASKDHGASKLFJL i got audio this time woo18:10
furynot sure what I did differently18:10
furyunplugged the pi, plugged it in, ssh'd in as soon as i could, systemctl start --user pulseaudio, went to media player, tapped the file that's on the USB flash drive, it started playing (though really choppy)18:10
furylast reboot, i did that exact same thing and mediaplayer crashed instead18:10
furytrying bluetooth now, but performance is not great, getting a lot of frame reassembly failed / sbc decoding error18:11
furybetter sound than the porter tho :D18:11
mdpsmurray: strangely, I started getting the 575-like behavior on my Nteenth boot of my porter build18:11
mdpFailed to create display18:11
smurrayfury: are you using the rpi built-in BT or a USB adapter?18:12
furybuilt in Bluetooth18:12
furyi can try the cinolink adapter, does that work better?18:12
smurraythere's a chance it may, yes18:13
furyi recall having the same frame reassembly failed / sbc decoding errors on raspbian the last time i tried it, maybe there's some problem in the hardware18:13
smurraythe firmware in the CSR ones is more of a known quantity18:13
furydoes it know to keep separate pairing lists for different bluetooth radios or do i need to manually forget/re-pair?18:14
smurrayheh, no idea, tbh18:15
furyor does it even know to use the CSR radio when it's plugged in O_o guess i'm bout to find out :D18:15
smurrayit should, the driver is there18:17
furysweet, paired up, got a second "raspberrypi3" entry in my phone's pairing list, i take it that means it's a different radio18:17
furymuch better performance than the built in pi bluetooth18:18
furyreally long buffer tho18:19
furyweird, still getting "No carrier" in afb-daemon and mediaplayer...is that gonna happen regardless of the fact that i started pulseaudio manually?18:19
mdpunpossible. rpi3 is a finely engineered machine, it can't possibly have worse performance than a cheap usb bt dongle ;)18:20
furyhahah18:20
furywhat'd i expect for a $35 computer, i guess18:20
furygah, i need another gechic display, someone's "borrowed" it for some other demo they want to do18:21
furythe AGL demo home screen is a little tiny on the pi 7" :P18:21
*** GillesF has quit IRC18:22
furyrygel is sending SSDP packets all over the place, is that normal? May 17 14:53:50 raspberrypi3 rygel[692]: ** (rygel:692): WARNING **: Error sending SSDP packet to 192.168.1.24: Error sending message: Invalid argument18:23
*** GillesF has joined #automotive18:24
smurrayI see those rygel messages as well, might be worth filing a JIRA issue over.  I suspect we can get away with disabling rygel in the default install, I don't believe anything uses it18:24
smurrayfor the "No carrier" messages, I've no idea, I do see them and wasn't sure if they're intentional debug stuff or not18:25
mranostayguess the afm changes are big enough need to rebuild my SDKs18:27
* mranostay grumbles18:27
mdpfury: I've been seeing them too..it's annoying..please file an issue18:30
mdpbetter from you than me ;)18:30
furywill do :D18:30
mdpfury, assign to mranostay ;)18:30
* mranostay runs18:33

furyso i think i may be at the point where i need to write a "hello world" AGL app (except instead of telling the user hello world, i'd like to connect to a given IP and send that over the network)19:56
furyis the AGL SDK to a point where i could do that? looks like https://jira.automotivelinux.org/projects/SPEC/issues/SPEC-247 is still open so maybe not, or maybe it's just a matter of command lines which i'm comfortable with learning19:57
*** jlrmagnus has quit IRC19:57
furymanaged to learn the setup/bitbake process, so shouldn't be too terribly hard i guess :D19:59
smurrayfury: we're making progress on the PA issue, I think20:04
smurrayfury: I'm about to test a fix locally20:04
furysweet :D i'm rerunning bitbake with the latest build to get ready to test too20:05
furyeeeeeh, qt 5.8. i mght be here a while :P20:05
smurrayheh, my change will trigger a massive rebuild20:05
furyawesome20:05
furyneed to exercise all these cores anyway :D20:06
smurrayplus you'll likely have to cherry-pick it for now, I think there might be some delay on merging it due to timezones20:06
furyERROR: When reparsing /home/build/agl/meta-agl-demo/recipes-platform/images/agl-demo-platform-crosssdk.bb.do_image_rpi_sdimg_ota, the basehash value changed from 277f03a4e561d7043ecaf47338cf1d30 to 0fff9f17711300d5a443cbecaab4c863. The metadata is not deterministic and this needs to be fixed.20:06
furyis that normal when building crosssdk?20:06
smurrayI'm not a SDK user, sorry20:06
furythat's ok, me either (yet?)20:06
smurrayI do know there has been some recent discussion about some Qt bits missing in the SDK, so it might be a bit dodgy atm20:07
furyah ok20:08
*** claneys has joined #automotive20:08
smurrayI don't see a JIRA issue right off, might have been on the mailing list20:08

furygoogle auto link? guessing that was the old codename for android auto...in which case, guessing that's gonna be a wontfix lol21:04
dl9pf_smurray: "pulseaudio: fix service/socket unit installation"  is all we need ?21:12
smurraydl9pf_: yes, that fixes PA startup here21:14
smurraydl9pf_: I'm working on another fix for the audiomanage stuff, I stumbled upon the root of that while digging, one of Isogai's changes didn't make it to master21:14

furywoo, i still crashed the media player by  trying to play a song off a flash drive :D22:28
furyis it supposed to be really choppy trying to play .wav files off a flash drive?22:30
fury(second time i opened it up it didn't crash - https://pastebin.com/vVGMVHs9 )22:30
mranostayfury: got any .oggs to test?22:30
furyshould be able to dig some up yeah22:31
furyuhh22:32
furyi rhink i just broke it again lol22:32
furyi changed the mixer volume to 100% cause it was too quiet, now May 17 14:55:35 raspberrypi3 pulseaudio[986]: W: [pulseaudio] module-loopback.c: Sample rates too different, not adjusting (44100 vs. 179554).22:32
furyevery 10 seconds a bigger number22:32
furyaudio stopped playing22:32
furygah22:32
furyi have to go home anyway, i'll try this in the morning with a fresh boot and whatnot22:33
*** jlrmagnus has quit IRC22:33
furyother than the above mentioned issues, smurray, pulseaudio did work for me without having to start it manually :D22:35
furyso your change works for me too22:35
smurrayfury: okay, thanks22:35
furynp22:36
