Hi Communitiy,
I've a problem with openAMP and debugging with SDK on procR5.
I'am able to run the openAMP echo example. everything runs fine.
If I attached the system debugger with SDK, everthing seems ok.
But if I start the openAMP example with:
echo testOpenAMP_freeRTOS_r0.elf > /sys/class/remoteproc/remoteproc0/firmware
the system crashed with Kernel panic. Where is the mistake?
Without attached debugger everything works fine!
Thanks in advance
