OEMiROT for STM32H523 MCU

[hakeila]

Hi,

I am working on OEMiROT bootloader for STM32H523. I have copied big parts of the ST OEMiROT example project from H533 example as this is the closest MCU to H523 from the flash memory layout perspectives.

However, it is taking ridiculously too long time to refactor the security parts of the project as the H533 does have more hardware security peripherals than H523.

I have cloned the STM MCUBoot and the ST Mbedtls repos in my project.

I would love to know if there is an OEMiROT project example(s) for H523 and if you have any recommendation on how to process this faster as it has been taking forever to refactor and recompile the H533 example on H523 MCU.

Cheers,

Hani

Hello, 

The STM32CubeH5 firmware package currently does not support the OEMiROT example on the STM32H523 device.

The OEMiROT example for the STM32H533 cannot be compiled on the STM32H523 device because the STM32H523 lacks support for the CRYP and PKA peripherals. For further assistance, please refer to the following wikis:
