uaelinuxhello09:24
CTtpollardo/09:24
uaelinuxwhat is best way to build  AGL on MAC OSX (sierra) ?09:25
uaelinuxor let me rephrase it, has any one build AGL on OSX?09:27
CTtpollarduaelinux: I don't think yocto has full native support for OSX, but I'm not certain09:30
CTtpollarduaelinux: can you use docker or parallels?09:31
uaelinuxnot a big fan of virtualization was hoping since OSX is bsd based there should be a native support09:33
CTtpollarduaelinux: You're probably better off asking directly in #yocto on this server09:34
uaelinuxthank CTtpollard09:34
CTtpollardAGL is a poky derivative, so if poky build on osx AGL should09:34
leon-anaviimho get rid of the mac os and use GNU/Linux distribution :)09:36
leon-anaviAccording to my experience Mac OS is good only for joining the GENIVI dev call each Wednesday ... and watching YouTube :)09:37
uaelinuxwell question is how hard is to port yocto/poky to darwin ?  Would it not give yocto/AGL access to darwin/macosx kernel developers?09:40
leon-anavihttp://www.yoctoproject.org/docs/2.1/mega-manual/mega-manual.html#detailed-supported-distros09:42
leon-anaviuaelinux, if you are in experimental mood you can give it a try on mac osx. It will be a hard task.09:42
leon-anaviIf you want to get the job done I recommend you to follow the official guidelines of the Yocto Project and use any of the recommended distribution in the link above.09:43
uaelinuxi agree  it will be hard task . I normally use MAC as it gives be best of both worlds (command line , gcc,python) and the support from closed source09:44
dl9pf_uaelinux: can you run docker ?09:52
uaelinuxyes, i think that is the only way to try AGL on mac as of now09:53
dl9pf_yes, use the docker container ...09:54
dl9pf_basically you can download the SDK  (look at this guide: http://docs.automotivelinux.org/docs/getting_started/en/dev/reference/setup-sdk-environment.html )09:54
dl9pf_there are never SDK's available ... so adapt the URL for the docker container import (see https://download.automotivelinux.org/AGL/snapshots/sdk/docker/ )09:55
dl9pf_https://download.automotivelinux.org/AGL/snapshots/sdk/docker/docker_agl_worker-generic-3.99.1.tar.xz   is the latest09:55
dl9pf_you don't need to install an SDK ... just use clone AGL inside the container09:56
dl9pf_aka we just need the docker/linux env of the sdk container to run bitbake09:56
uaelinuxthanks dl9pf09:57

Tartarushey dl9pf_, are we moving rpi3 over to 64bit?  Or rpi foundation firmware? I'm confused by the uImage->Image change11:47
dl9pf_Tartarus: no, there's the 32bit variant and there's a MACHINE="raspberrypi3-64" in review .11:49
TartarusSo https://gerrit.automotivelinux.org/gerrit/#/c/9727/3 is still wrong then, yes?11:49
TartarusSince we need uImage and bootm for the 32bit targets11:50
dl9pf_more likely aligning with upstream ... @leon-anavi is on it atm.11:50
dl9pf_why do we strictly need uImage ?11:51
leon-anaviI have switched from uImage to Image for machines raspberrypi3 and raspberrypi2 because otherwise AGL failed to boot on these boards.11:51
leon-anaviThe change is currently in a review in Gerrit: 972711:52
leon-anaviIt is related to the issues described in SPEC-649 and SPEC-65011:52
leon-anavior in other words these two issues describe that AGL fails to boot on rpi3 therefore the fix from change 9727 is required.11:53
Tartarusleon-anavi: Can you log the serial console on a successful boot?11:53
leon-anaviyes, with Image and no with uImage.11:53
leon-anaviwith KERNEL_IMAGETYPE = "uImage" there is no output on the serial console at all.11:53
TartarusYeah, I wanna see what's going on with Image11:54
leon-anaviTartarus, rpi3 or rpi2?11:55
TartarusBoth if you can easily, but 3 if you don't have the 2 setup atm11:56
*** fredw has joined #automotive11:56
*** claneys has joined #automotive11:59
leon-anaviI have a rpi3 setup atm12:00

leon-anavihttps://gist.github.com/anonymous/dfe0f7851b04f2befda880e5c0d7ab1c12:08
Tartarusleon-anavi: So there's nothing at all from U-Boot then, right?12:10
*** kbroulik has quit IRC12:12
*** kbroulik has joined #automotive12:12
Tartarusleon-anavi, dl9pf_, it looks like as I thought, we're switching out U-Boot for the rpi foundation firmware.  Is that intentional?12:13
TartarusI'm biased and all, but that's still fine, so long as it's intentional and not a side effect :)12:13
leon-anaviThe agl-sota feature relies on u-boot because of ostree12:14
leon-anaviin meta-agl we have copied sdcard_image-rpi.bbclass from meta-raspberrypi (with a minor change).12:14
leon-anaviIn this class u-boot.bin is deployed if KERNEL_IMAGETYPE is uImage.12:15
TartarusRight.  But that boot log, without any U-Boot prints, is then just going with the rpi foundation firmware12:23
TartarusCheck out what kernel*img is12:23
leon-anaviyes, it is, because it is with Image12:28
leon-anavithe boot log is from the regular AGL, aka without feature agl-sota12:28
leon-anavimy change from uImage to Image is applied therefore it uses the rpi foudation firmware12:29
leon-anaviIf I add agl-sota feature the meta-updater layer will be used, KERNEL_IMAGETYPE should be set to uImage and then u-boot should be used instead as it is required for OSTree.12:30

khilmanTartarus, leon-anavi: I'm still trying to understand the goal of removing u-boot.14:31
khilmanIMO, that makes CI harder, as it removes a lot of flexilibity in custom kernel/dtb/ramdisk14:31
Tartaruskhilman: I would assume that it's about matching meta-raspberrypi as that doesn't default to U-Boot, but I agree wrt CI14:33
leon-anavikhilman, AGL from master wasn't working on rpi3 and rpi2. The latest release of the previous version of AGL chinook is working. By comparing the differences I noticed that in chinook the KERNEL_IMAGETYPE is Image therefore as a hot fix I reverted the value of KERNEL_IMAGETYPE from uImage to Image in the master branch of AGL.14:33
leon-anaviThis is how Change 9727 appeared in Gerrit.14:33
leon-anaviSome details were reported in JIRA: https://jira.automotivelinux.org/browse/SPEC-649 and https://jira.automotivelinux.org/browse/SPEC-65014:34
khilmanI'll have to have a closer look at that (after some meetings)14:34
khilmanbut seems an alternate solution would also be to fix/upgrade uboot on whatever boards were failing.14:35
khilmancurious: how is the SD card being (re)written to get a new kernel on every time?14:35
leon-anaviAGL has a feature called agl-sota which requires additional layer meta-updater. This features works with u-boot in rpi3 and it boots, although there are some other issues with agl-sota.14:35
khilmanso are you saying that feature is broken without uboot?14:36
leon-anavikhilman, in meta-agl there is a copy of sdcard_image-rpi with a minor modification: meta-agl-bsp/classes/sdcard_image-rpi.bbclass14:36
leon-anaviprobably the right way will be to upstream this modification to the upstream of meta-raspberrypi and after that delete the copy of the class from meta-agl.14:37
furyIf I take the kernel7.img from the last dab RC snapshot (5-30) and plop it down into the boot folder of a recent build, it boots (uImage and all) - might be better to track down what caused kernel7.img to break maybe?14:37
furythough I’m not sure how to tell what causes that to change14:37
furyall I know is I was fiddling with replacing the entire boot partition on a recent build with the old one from May, and narrowed it down to kernel7.img14:38
leon-anavikhilman, yes, agl-sota relies on u-boot. This feature brings software over the air updates to AGL based on OSTree and Aktualizr (developed by ATS Advanced Telematic Systems)14:38
furyI have no idea how that and uImage/Image relate14:38
leon-anavifury, as soon as Change 9727 is merged you will have to same experience without manually copying kernel7.img from older versions :)14:39
furyBut at the same time it’d be cool to have sota. Do I kill sota by using the kernel7.img they works?14:41
Tartarusfury: what is the content of that working kernel7.img tho14:41
furythat*14:41
Tartarusis it u-boot or a linux kernel?14:42
furyHmm. Good question. It flashes by so quick, I’ll have to try and watch it closely14:43
furyUnless there's a way to edit the file in a hex editor to find it14:45
TartarusWell, how big is it?14:45
Tartaruskilobytes would be U-Boot, megabytes would be linux14:45
leon-anavithe generation of kernel7.img is done by class meta-agl/meta-agl-bsp/classes/sdcard_image-rpi.bbclass14:49
*** chbae has quit IRC14:54
furyit's 338 kb14:54
furyso it sounds like it's uboot14:54
furyif it's uboot does that mean sota should work?14:57
furyi've been meaning to play around with sota, maybe now's a good time :P14:58
*** jlrmagnus has joined #automotive15:02
furyi just had to reboot my laptop's keyboard ._.15:02
furybecause it was preventing the thing from booting15:02
furyi am tempted to never buy another lenovo as long as i live15:03
CTtpollardI have a few mobo's try to first boot from usb keyboard/mice before15:04
furythen again, the form factor of this thing was dubious at best. lower 3/5ths of it is a detachable keyboard/trackpad/battery dock, the firmware in the thing gets hung up when the dock's battery dies15:04
furyso i plug it in and it doesn't start charging, nor does the system boot at all - i have to pull out my trusty used-to-be-a-paperclip reset button pusher / sim removal tool and hold in the reset button for it to get unhung15:05
*** khem` is now known as khem15:07
*** kbroulik has quit IRC15:12
Tartarusfury: Ah, so, we should figure out what broke U-Boot functioning in agl then between point A and B15:14
TartarusIt's possible it was a meta-raspberrypi thing is we didn't pin stuff down well wrt layers out of our control15:14
furysounds good :) well, it was working on the pi as of 5-29 (and i think the dab RC on 5-30) and it was broke as of 6-03 - i was in the middle of downloading the snapshots between those dates to try to narrow it down further but then they were deleted from the AGL download server :P15:15
furyand all that i replaced in the 6-03 build was the kernel7.img from the older build15:16
furyand it booted15:16
furyso i dunno if there's a way to examine every single git commit in the corresponding repos, but that was what i was aiming for - i just couldn't find a way to tell anything except for the gerrit changes submitted to the meta-agl layers15:17

mranostaykhilman: question does an aarch64 build of rpi3 boot to HomeScreen?18:41
JEEBI thought the drivers weren't really all ready? although I guess SW rendering could be possible into a framebuffer18:41
*** akilaw has joined #automotive18:42
mranostayJEEB: heh painfully for sure18:42
JEEBalthough aarch64 seems to be "work complete" since March? https://github.com/raspberrypi/linux/issues/191518:42
JEEB(granted, some patches were still in -next at that point)18:42
khilmanmranostay: I have no idea, just trying to get the 64-bit kernel build part working.18:43
JEEBthat should be possible with a recent enough kernel18:43
khilmanbeing new to AGL, seems like a chicken-egg problem though to have to show that it boots to homescreen before merging patches to build it.18:44
mranostaykhilman: no judgement just curious :)18:44
khilmanjust waiting for a full build to finish now so I can try to boot it and see what happens18:45
JEEBhmm, not sure which exact version and/or patch set gentoo is doing, but they say wifi,usb,ethernet,bluetooth,hw video (as in actual motion video decoding), sound over hdmi18:46
JEEBwork18:46
JEEBwhich I guess is better than I expected with regards to video18:46

khilmanhowever, there is one generated for raspberrypi3-6419:43
