Programming M core on iMX8MP

[jospuntnl]

Hi,

I've been trying to program the M-core of the IMX8MP for a while now, and after messing around with memory adresses, I've finally got a firmware file that does not immediately get rejected. Sadly I've ran into another issue:

Code Select Expand

[  412.455146] remoteproc remoteproc0: powering up imx-dsp-rproc
[  412.462385] remoteproc remoteproc0: Booting fw image hello_world.elf, size 185848
[  412.585249] remoteproc remoteproc0: can't start rproc imx-dsp-rproc: -110
[  412.585353] remoteproc remoteproc0: Boot failed: -110

Can anyone tell me what's wrong? I'm running the official minimal Debian OS, on the official evaluation board.

My advice is to search and then post in the NXP forums. I see similar error massages in this thread here:

Thanks for your answer. The thread you linked is about the memory issue, which I luckily was already able to solve. I am really looking for the reason why the core itself won't start.
