I'm using H753 which has hw crypto, and was hoping to improve the sbsfu execution time (e.g. time to validate FW header at start tup) by enabling hw crypto. However HAL_CRYP_MODULE_ENABLED doesn't do anything. I looked through the integration guide a...

Am testing the x-cube-sbsfu on H7A3 (using H7B3 project with OTFDEC disabled). After enabling SFU_MPU_PROTECT_ENABLE, I always ran into mem manage fault when the function HAL_RCC_GetPCLK1Freq is called during HAL_UART_Init: An MPU or Execute Never (...

Hi experts,I need to implement the storage of a security key (upgradable) on STM32H7A3. After reading the example code of KMS under project B-L475E-IOT01A in x-cube-sbsfu, and a few posts in the forum (KSM support on STMH7 and 2-images-kms-port-to-s...

FMC bank 1 is set to NOR Flash PSRAM, bank 3 is set to NAND Flash. The transfer of NAND flash uses DMA.MPU of the above regions are set to non-cacheable, non-buffable, non-shareable.The issue occurs when PSRAM read happens during NAND flash read. The...

I figured out why and RCC's MPU protection is not the culprit: the MPU setting for internal flash is set to instruction execution disabled.

I have searched the web: several posts had similar issues and they could fix it by setting up MPU but it doesn't work for us. We set 3 memory regions: external flash (16MB), external RAM (8MB), NAND flash (256MB).If there is anything missing please l...
