Save kernel OOPS/Panic in RAM and read after reboot

Hi
We try to implement store the kernel OOPS and Panic using the kernels “ramopps pstore oops/panic logger”
pstore-block-oops-panic-logger
ramops

Therefore we need a part of the DDR3 RAM of the Colibri iMX6dl that stay consistent after a reboot.
We need to reserve a part of the RAM and disable the initialization in the SPL.
Is the HW capable/ready to reboot without loosing the content of the RAM.
Has someone experience with this topic or is it already available?

Thanks for your help
Stefan

Hi @StefanB

Thanks for writing to the Toradex Community!

Has someone experience with this topic or is it already available?

I did not hear about this panic logger but I know about Kexec and Kdump which is working for the kernel 4.14. Does this fits your needs? If yes, you would need to try this out for iMX6DL since it was only tested for iMX7 till now.

Best regards,
