What could be the issue?

is your hart set on using such an old image ??
there is a 2023 image, can you try that and see if you get the same issues

Hi amf99,
thanks for your advise. Yes I know that is an old debian kernel I am using since years until I face those issues described in my files. I will need to install all modules for NI-USB visa and of course drivers for uio pruss. we are using this instead of remoteproc because we had already some api that could build and generate pattern and this was done with uio pruss.
I was hoping to solve this issue keeping the same kernel but you are maybe right to jumb to new image. is this image having Cloud9 installed?

I don’t have clue about what is going on with your board, this is all conjecture.

It appears the kernel is having an issue with memory rs:main. Since that is an old kernel I would suspect it has been running perfectly until this point. Hence, might be the ram has an issue. It might have some logs that have now filled up all the emmc??? If you can jump start it on SD card and mount emmc then look around and see if that is filled up. This is just a guess, not having the board and intimate knowledge of the code makes this difficult.
