kernel panic with CM4 images

[besttest-creator]

After running in the issues with the Zero 2W, I was able to get my hands on a CM4 Lite with 8GB of RAM. In combination with a SanDisk Ultra 265GB I get a kernel panic on almost every boot.

So far it happend on all OS-CM4 Images I tried. It does't seem to make a difference if Raspi Imager or Etcher is used. Even the CM4 carrier board was already exchanged, just in case the soldering to the SD-card might be the issue. That was not the case.

Anybody any idea?

Thanks! besttest

"After running in the issues with the Zero 2W" Are you saying you had issues with the Zero as well?

Which image are you using on the cm4, and have you tried any of the ones on my drive?

edit: just saw the other issue you created. im giving it a read through.

I will continue testing on the CM4 module tomorrow with more pictures. So far I have seen the problem with kernel issues on:

• CM4- PSPi 6 RetroPie Beta 2023.10.07.img.gz --> Does not start, freezes entirely.
• PSPi 6 RPi OS 32bit 2023.11.12.gz --> Needs to be tested again. The "PSPi 6 Lakka 3.7 32-bit CM4 2023.11.17.gz" --> does only boot after ~8 attempts and the games freeze after a few minutes.

I added a new RetroPie CM4 image to the proton drive folder. Care to give it a try?

I did get to try your newest RetroPi image for the CM4 module. I tested it with raspi Imager like you described in details.txt.

On first boot it seems to run in a kernel issue

The second boot did get into the emulation station but crashed

Now it only starts until it gets stuck in the RetroPi screen

Thank you for your efforts, I'm sorry i didn't get to test earlier.

Burned the image on etcher and it seems to run without a kernel issue on first boot. As soon as I added wifi and booted it the second time it get's stuck on the RetroPi screen again. Best regards

Do you have a smaller SD card you can try?

[besttest-creator]

Doesn't matter how many i have, I'm always one card short. I'm waiting for the delivery of a second SD card, I hope it will arrive sometime during next week. Then I will also continue testing more thoroughly, otherwise I would need to delete the working Zero2W image every time for the cm4 image. Best regards

Not entirely sure if this has been ruled out yet, but have you tried a different SD Card reader/writer to burn your images? I had a plethora of issues attempting to burn LAKKA 64bit on my windows computer, with 4 different SD card adapters. Eventually, I had to boot up my old MacBook to write the image, and only then was I able to get the SD card written successfully.

*Note: I did not experience this specific kernel panic issue, but general write failures on the SD cards in general. Wouldn't hurt to try, just for the sake of completeness. 🤷‍♂️

I have tried only one card reader so far, but I just ordered a second one from amazon. The new SD card already arrived but unfortunately I need to get a new PSP for a second PSPi build first, because I gifted the latest build in the family for Christmas. I will get back to this as soon as I have everything setup and plan to give this a thorough testing from every angle I can imagine. Best regards

I made lots of changes to the Lakka, RetroPie, and Raspberry Pi OS images recently. Want to give it another try?
