IAC exceptions when launching M33 core

[nielsenni101]

Hello,

I am trying to load an .elf file on the M33 core on my stm32mp257f processor. When I launch the remote core using remoteproc I get the following errors.

root@stm32mp257f-hydra-mx:~# echo -n /home/root > /sys/module/firmware_class/parameters/path

 Any suggestions?

Hi @nielsenni101 ,

Seems you are trying to start an unsigned .elf while by default OpenSTLinux requires a signed binary. 

Note also that running M33 firmware requires appropriate Riff configuration. 

In Starter package you might use m33-exemples flavor of tsv. 

Please check Wiki : 

Modify, rebuild and reload the firmware - stm32mpu

Hope it help 

Olivier
