Incompatible Hardware: Lenovo ThinkPad C13 Yoga Chromebook (MORPHIUS) - 2020 model about breath HOT 31 CLOSED

Closing this old issue. Reopen @ChrisTitusTech if needed.

from breath.

Should be fixed now since I modularized AMDGPU, giving it firmware access. Try running bash updatekernel.sh on your Linux PC (not your chromebook).

from breath.

Hey Chris! are you planning to make a video on this project? That would be epic!

from breath.

Yeah, checking out all the different ways to bypass ChromeOS's janky firmware. I hate it.

Breath looks amazing, currently I'm using coreboot from mrchromebox firmware to get around it.

from breath.

Are you using Mr. Chromebox's firmware with this project? This only works with stock dev mode ChromeOS firmware.

from breath.

I've just noticed you have an AMD Chromebook. I don't have any AMD chromebooks to test on, but I'll still try to get it working :D

from breath.

Thanks Milky I'm sure the Ryzen firmware is causing this. Its a lot different than the intel chromebooks, but also more powerful.
Using the bypass and install stock linux using the chromebox coreboot firmware method has some strange results. The touch screen with rotation is all over the place and sound of course is a sore spot as well.
Touchpad and other features do work. The only other thing I see is the standby states are pretty jacked and will need to be tweaked to work with stock linux.

from breath.

I think breath would be a much better solution. I'm going to revert everything to stock with dev mode. I'll keep going with a linux container, but let me know if you need a lspci or any readouts from this system.

from breath.

I think it should be fixed now, I compiled in amdgpu drivers. Update the git repo (git fetch; git pull), plug in a USB, and run:

bash updatekernel.sh

Let me know if it works (since I don't have an AMD chromebook)!

from breath.

updated the usb drive with bash updatekernel.sh and then tried again with Ctrl U at startup. Still just getting a black screen

I did do a fresh clone on a new drive to see if that changed anything, but alas still just a black screen. Darn those AMD drivers... I think it could also be the touchscreen as well. It's one of those Lenovo screens that can do a full 360 degree swap to "tablet mode"

from breath.

YOU ARE THE MAN! ... Worked like a champ.

from breath.

Just wondering, could you try making a video over this :D? I think if this project had a bit more exposure I could get more contributors and testers for more chromebooks supported. Thanks!

from breath.

I recently also got audio working on AMD Chromebooks (#24) :D

from breath.

Awesome! Yeah, I'm definitely going to make a video on it. The biggest issue I'm having now is getting it moved from USB to internal storage. The bin/internal-storage script isn't working for me. Sooo close to building it into a sweet little linux laptop.

from breath.

I've just now fixed the install to internal storage script, just run:

sudo wget https://raw.githubusercontent.com/MilkyDeveloper/cb-linux/main/bin/install-to-internal-storage -O /usr/local/bin/install-to-internal-storage

and then

sudo chmod +x /usr/local/bin/install-to-internal-storage

Although I don't have an AMD Chromebook, i've had users report that running my sof-setup-audio script works. Since you've installed it earlier than when I released it, you could run:

sudo wget https://raw.githubusercontent.com/MilkyDeveloper/cb-linux/main/bin/sof-setup-audio -O /usr/local/bin/sof-setup-audio

and then

sudo chmod +x /usr/local/bin/sof-setup-audio

from breath.

This worked absolutely perfectly on the internal storage. Much faster than usb as my chromebook has an nvme.

Running like a dream. Now to build out my system. I can't wait to see the FPS difference in steam games.

from breath.

That's awesome! Do you think I would see a performance increase using the internal storage over my 32gig MicroSD card? I have 64GB of eMMC storage.

from breath.

Yes, I experienced a performance boost when installing from a common Sandisk SD Card to my EMMC.

from breath.

Few things I'm noticing with Debian.
using sof-setup-audio the audio doesn't work. It's looking for alsa-base package which doesn't exist in debian
Another notable thing I haven't figure out is re-mapping the "chrome keys" at the top of the keyboard to F-Keys or something else.
I'd say these are the last things from keeping it from being complete for me.

from breath.

I've fixed the sof-setup-audio script:

sudo wget https://raw.githubusercontent.com/MilkyDeveloper/cb-linux/main/bin/sof-setup-audio -O /usr/local/bin/sof-setup-audio

and then

sudo chmod +x /usr/local/bin/sof-setup-audio

As for the keymappings, it might take me some time to implement this. I don't want something that depends on X11, but I need to support X11, Wayland, and the TTY.

from breath.

Still having issues with sound. Looks like it might be an AMD issue as I'm not seeing a driver for any of my audio or multimedia outputs of lspci -kk.
Here is my an abridged output. Getting a kernel module loaded for my sound is my first step.

from breath.

Here is the kernel driver readout

.

from breath.

A good starting place would be modprobing sof-pci and sof-pci. Why don't you post the output of lsmod within the ChromeOS shell (not Crostini) to find out which modules are needed?

from breath.

I wiped out all my ChromeOS and installed it to internal storage.
Here is my lsmod output:

I'd start by running modprobe snd_sof_pci snd_sof_pci_dev snd_sof_intel_hda_common

from breath.

Modprobe was successful run on snd_sof_pci and snd_sof_intel_hda_common
Modprobe did not find snd_sof_pci_dev

No effect before or after reboot aplay -l still lists no soundcards found.

I'm thinking the hardware might be too new for the 5.10 kernel.

from breath.

Then again, I do recall in the latest ChromeOS update 98 dev build... sound in the linux containers started working where in prior builds it did not.

from breath.

Could you post the dmesg? Might be something about firmware.

from breath.

This is my dmesg output:
dmesg.txt

from breath.

Looks like the card is now recognized and even shows in aplay -l however no sound.

I did loadup alsamixer and it showed the sound and I was able to adjust volumes, but again no actual sound came from the speakers.

from breath.

Looks like this was a kernel issue. Maybe retrying the latest release from the docs would work? The kernel has been updated a lot since I last made progress on this issue.
