Cannot boot an m33 TA app from the RFS on a STM32mp257f-DK board running latest OpenSTLinux starter package image.
Any assistance would be appreciated. Please see details and boot error below.
STEPS USED:
1) build a TA m33 application in STM32CubeIDE
2) from PC ssh .elf file - 73551a82-b721-4e53-9c84-c962e172c8ad.elf to target dir /lib/firmware
3) from PC ssh .ta file - 73551a82-b721-4e53-9c84-c962e172c8ad.ta to target dir /lib/optee_armtz/
4) from target terminal invoke command: root@stm32mp2unknownunknown:/lib/firmware# echo 73551a82-b721-4e53-9c84-c962e172c8ad.elf > /sys/class/remoteproc/remoteproc0/firmware
5) from target terminal invoke command: root@stm32mp2unknownunknown:/lib/firmware# echo start > /sys/class/remoteproc/remoteproc0/state
TARGET TERMIAL OUTPUT:
