Remoteproc error

[nielsenni101]

Hello,

I have compiled a custom image to run on the M4 core on my stm32mp157f-dk2. I generated the code using STM32CubeMX. I am able to build it fine but am having issues launching it on the m4 core. Here are the commands that I run.

echo executable.elf > /sys/class/remoteproc/remoteproc0/firmware
echo start > /sys/class/remoteproc/remoteproc0/state

The output I get is this

root@stm32mp1-brady:/lib/firmware# echo start > /sys/class/remoteproc/remoteproc0/state
[  169.647382] remoteproc remoteproc0: powering up m4
[  169.651669] remoteproc remoteproc0: Image is corrupted (bad magic)
[  169.657239] remoteproc remoteproc0: Boot failed: -22
-sh: echo: write error: Invalid argument

 I could not find a clear solution or cause to this. Does anyone know what this error means? 

I am able to run the OpenAMP_TTY_echo.CM4.elf on the M4 core using the same commands with no issues.

Thanks.

Hi @nielsenni101 ,

Did you test that your application is running find on engi boot ? 

Maybe comparison between CubeMX generated project and working exemple may help to identify the issue
