RiyadI am having a hard time starting agl-service-can-low-level using afm-util start agl-service-can-low-level i get :ERROR:  cannot-start09:30
RiyadI am on master branch (9.90.0 Jellyfish) using the pre built image for RPI4 and PiCan3 CAN Shield09:31
dl9pfRiyad: please us the latest 9.99.2 or the daily snapshot.10:01
dl9pfhttps://download.automotivelinux.org/AGL/snapshots/master/latest/10:01
dl9pfthere was a fix merged for 9.99.210:02

Riyaddl9pf Interface is super zoomed in on the lastest version on the RPI 7 inch touch screenn. Is that normal ?11:49
smurrayRiyad: scaling support has been dropped with the new compositor.  You pretty much need a 1080p screen for the demo image now11:51
RiyadI see, I guess i'll have to use an older version then11:53
RiyadWhich version I could use to get the agl-service-can-low-level and signal composer working with CAN Shield ?11:55
smurrayhalibut for sure, icefish might need some work to update the agl-vcar CAN messages in can-low-level11:57
RiyadWill Halibut support RaspberryPi 4 ?11:59
smurrayyes12:02

biotwhen running agl-demo under qemu, the display window is rotated 90 degrees, and the mouse if off by 90 deg as well... is there a way to fix this?14:45
biot(icefish, from git)14:45
jbponsIn the file /etc/xdg/weston/weston.ini make the following change : transform=270 => transform=>36014:49
jbponsbiot: transform=270 --> transform=36014:50
biotaha, will try that14:51
jbponsDon't forget to reboot to apply the change14:54
biothmm, didn't work14:57
smurraynote that 360 = 014:58
smurrayso if you want no rotation, just comment the transform line out14:58
smurraythe assumption in the demo setup is 1080x1920, hence it being rotated14:59
biotthat transform= line doesn't seem to make a difference, neither 270 nor 90 does anything14:59
smurrayif you want it upright with in qemu, I'm not aware of a way to do that right off15:00
biotso how are people developing? it doesn't seem very usable with qemu in that case15:01
smurrayI don't find it too bad for testing15:02
biotwith the mouse going 90 deg off from usual?15:02
smurrayI don't see that here15:02
smurrayI'm using runqemu inside the build tree most of the time, though15:03
smurrayJan-Simon (dl9pf here) might have an idea15:03
biothow does that runqemu thing work? I thought "bitbake runqemu" but that's not it15:04
*** kooltux_ has joined #automotive15:05
dl9pfbiot: "bitbake agl-demo-platform"    then call "runqenu"15:05
dl9pfor "runqemu slirp kvm"15:06
biotd'oh15:06
dl9pfyou need to be in the bitbake env  and have the image built to call runqemu15:08
biotyup, runqemu slirp kvm works, and the weird mouse rotation thing is gone15:09
smurraythat suggests there's a qemu option different between what runqemu is passing and what you were doing manually15:09
biotwell, I was just using the qemu cmdline from the wiki15:10
smurrayit wouldn't shock me if that was stale15:10
biotno, from the docs15:10
biothttps://docs.automotivelinux.org/docs/en/master/getting_started/reference/getting-started/machines/qemu.html15:11
dl9pfbiot: if you use runqemu it uses a built-in qemu binary ... if you just use the cmdline it is your hosts version15:11
dl9pfcheck qemu-system-x86_64 --version  vs what runqemu outputs15:12
biotah, I see now this is the thing that uses that qemuboot.conf file15:12
dl9pfyes15:12
biotqemu sure didn't like it with -readconf :)15:12
jbponsDifferent topic : do we have an example of native app which use the agl-service-can-low-level to write on the CAN bus ?15:13
smurrayjbpons: hvac in recent versions does15:13
smurrayjbpons: sorry, agl-service-hvac15:15
jbponsOk cool ! Thanks !15:16
smurrayjbpons: since icefish.  I've not tested it recently, though15:17
jbponsok15:18
smurrayjbpons: I'm currently fixing some things in the CAN binding on master, you likely will have issues on most platforms except for m3ulcb/h3ulcb ATM15:18
smurrayjbpons: icefish may be missing some of the CAN message definitions, so I'm not sure ATM if it's working15:19
jbponsOk ! I'm still working with halibut version on raspberrypi3. I'm working on a basic app with is able to display all CAN signals (as candump) but using the signal-composer. Now I want to enhance this app by adding the possibility to write on the CAN bus through agl-service-can-low-level.15:24
*** d__ep__th has quit IRC15:25
jbponsthat's why I want an exemple of app using the agl-service-can-low-level to write on CAN bus15:26
smurrayjbpons: the code that's in latest agl-service-hvac should give you an idea15:28
jbponsyes i'm reading it, is exactly what I need15:30
jbponsthanks smurray15:30
smurrayjbpons: good luck15:31
*** kooltux_ has quit IRC15:32
biotaha, you need to change that transform= in the right *section* of weston.ini :)15:37
smurrayah, yes, it's specific to the output15:43
