Dear ST Team,
We are working on enabling and running the Cortex-M33 core on the STM32MP257F-DK board using U-Boot v2023.10-stm32mp-r2.
https://wiki.st.com/stm32mpu/wiki/How_to_start_the_Cortex-M_coprocessor_from_U-Boot
Despite following the procedure described above link from the ST wiki, we are unable to successfully load or start the M33 firmware from U-Boot.
- The rproc load command returns load remote processor failed. Please refer the screenshot for the error message.
- rproc start,rproc stop,rproc ping returns Operation Failed with error (-19)
- rproc list command returns no output.
- We are facing issues while accessing certain registers using the md command in U-Boot.Specifically, attempting to read RAMCFG registers causes U-Boot to jump into its error handler.
Thanks in advance
Best Regards
Akshitha Pattem
