hexdump0815 commented 2 years ago

notes on cozmo running 5.19.1:

here is list of working and non working features on the acer cb314-2h / cb314-2ht (cozmo). i just had some limited time to do some tests on the non touchscreen 4gb version.

working

wifi
bluetooth
builtin display
usb a and c for basic usb functionality
gpu opengl: via mesa panfrost (opengl 3.1)
builtin speaker and mic

untested

hw video encode/decode: most probably not working yet
energy: dpms, suspend/resume
webcam

broken

trackpad not discovered (looks a bit like wrongly configured i2c) - might be fixed in the latest image, see discussion below
battery not discovered
sound: only internal speaker and mic working so far, more ucm profile work required
external display: not working yet

installation

coming soon

problems

no trackpad, external usb mouse required until this is fixed
no battery info yet

The trackpad worked with https://github.com/hexdump0815/imagebuilder/releases/tag/230218-01 using the jammy image right out of the box. :)

i'm happy to hear this - maybe the newer kernel in this image helped

The touchscreen works - tested with the 8gb version

For my device the trackpad works only every other boot. I can observe trackpad issues sometimes during one of my fresh installs.

my command to install every time i try again: sudo dd if=chromebook_kukui-aarch64-jammy.img bs=1M of=/dev/sd(X)

I would want to know if there is any issue or a detection problem I don't know about when running this command consecutively on a sd card.?

After observing the trackpad working, then not working every other boot for a few times, I got this after the boot phase:

I can no longer boot into the image and have to wipe it.

I don't know if that would happen on emmc, I have not tried it yet and I don't know if I can do that without a suzqable. @hexdump0815 You have mentioned earlier in the readme if I run out of battery I may lose the data, that is not a problem, but I don't know how I can write to emmc?

I usually expand root partition after with the script in /scripts.

more notes:

battery displays a percentage for me on xubuntu , my device seems to last ~6 hours
I tested updating mesa drivers with the script, I think they fix black blotches that appear when scrolling, with hardware acceleration enabled in firefox
touchscreen and keyboard worked on all boots
the jack update script broke the detection of pulseaudio server, and did not work with my earphones

@Zant12 - thanks a lot for the feedback ... for installing onto emmc please have a look at https://github.com/hexdump0815/imagebuilder/blob/main/doc/install-to-emmc-on-arm-chromebooks.md ... the errors you get look like problems with the usb storage device, maybe try some other one

Zant12 commented 7 months ago

Thanks! I flashed to emmc (the simple dd method), and Im not seeing any of those previous issues. Installed like this:

./expandrootfs > sudo apt update && upgrade & reboot > install & make timeshift backup > install build tools > install latest mesa drivers

Thanks for letting me know about the sd/card usb, I have no sd card reader actually on this variant so I used a cheap sd reader device like this which has better ergonomics so I dont knock out my usb stick when carrying the chromebook. I think this is the cause of my problems.

I don't see any of those issues I mentioned previously after a few reboots. Thanks for everything, great guide! I found the "chromebook arm" github page by googling, so I'm unfamilar with previous iterations of the project and only usually familar with balena etcher. That does work too.

Eventually found out how to increase the size, would it be ok to add that too in the "chromebook arm" page?

it looks like the touchpad problems depends on the actual hardware version: i just tried the above mentioned working 230218-01 image on a cozmo here and it does not work ... so touchpad might work on some systems currently and not on others ...

Zant12 commented 5 months ago

I have been daily driving the laptop on the emmc all this time, and really love how the battery lasts for such a long time. Even if I don't plug it in for a few days it retains it's charge in suspend.

I hope to report some bugs i encountered in case it help you improve the images.

the suspend option doesnt always work. I usually manually click suspend, then close it. occasionally I see the screen is on and frozen when I reopen it. Then I have to restart. I'm pretty fine with a restart as I usually save and work and use mainly just use the browser(s). but it does work often
on very rare occasions, I have had the touchpad be unresponsive after booting back in.. something strange might have happened during the boot process, and its not really something reproducible.
Sometimes, with 30+ tabs and lots of swapping, my driver disconnects and you see black patches and can't watch videos (it becomes a slideshow), until you restart

It's all rare bugs though
