Could you please share more about your environment like what all packages from khadas repository have you applied, what command are you using that we can use to reproduce the issue, etc

sousmangoosta · May 13, 2024, 3:55pm

Sure, that follow the other issue I got before : here
So I added optee-userspace_0.5-202311_arm64.deband optee-video-firmware_0.4-202311_arm64.deb from https://dl.khadas.com/repos/vim4-5.15/pool/main/o/
I installed ffmpeg with apt install
I created a yuv file with ffmpeg

I’m posting the kernel panic because when trying to use my camera with ffmpeg and hardware acceleration yesterday I add the exact same kernel panic I took on picture but didn’t have the serial port connected.

Thanks for sharing, I will try to reproduce the issue and will get back to you on the same.

sousmangoosta · May 13, 2024, 4:04pm

Maybe that can help too, when I have no firmware loaded (tee-supplicant and video-firmware-preload-khadas services disabled), I have an other kernel panic but similar.
