Hi,I’m working with the STM32H7S7L86H and using the SAES peripheral to encrypt and decrypt data stored in an SPI flash.I currently have the peripheral working correctly using HAL functions in polling mode. I also managed to get it working with interr...
Hi, I have an STM32H7S78-DK board and am working on encryption. I’ve looked at the example files for STiROT_OEMuROT: https://github.com/STMicroelectronics/STM32CubeH7RS/tree/main/Projects/STM32H7S78 -DK/ROT_Provisioning/STiROT_OEMuROTI’ve tried that ...
I am implementing a secure boot process on the STM32H723. My application has three firmware components with the following memory layout:1. BOOT: Located in internal Flash.2. OS: Located in internal Flash.3. USER: Located in external SDRAM.The require...
In STM32Cube_FW_H7RS_V1.3.0, file Projects\STM32H7S78-DK\Applications\ROT\OEMiROT_Boot\Inc\stm32_extmem_conf.h:The configuration for the external RAM (presumably for an APS256XXN-OBR-BG, since that's what on the DK) is incorrect. In particular, it do...
I have an application that uses the OCTOSPI1 interface to read from and write to an external NOR flash memory into an SRAM1 buffer. The read and write operations are performed in the NS section of the application. If I perform a transfer without usin...
Hello,After spending several days investigating this topic and reviewing all the documentation I could find, I am still completely stuck on how to proceed with implementing STiROT + OEMuROT on my STM32H7S3.An important point is that I am trying to ad...
Hi!My application requires NIST-compliant random number generation, and I see some unclear/contradicting info on the Reference Manual, the AN4230 application note, and the public NIST certificate. My MCU is STM32H563ZI.- Reference Manual: https://www...
HiI have STM32H563 Nucleo board which is in closed state with DA_Config.obk not programmed, And the trust zone disabled. This was done by mistake, Is there a way to do regression on it.Operations Done on the device.1.Done the regression2.Set the prod...
Now that that the CRA dates are near, why is there isn't a forum for regulatory compliance and CRA specific questions ?For example, which products STM offers now will not be CRA compliant ? This is important as those products would have to be revise...
On an STM32H563, I am trying to write the OBkey1 data.I have successfully set the product state to provisioning (0x17) with: FLASH_OBProgramInitTypeDef optionBytes; HAL_FLASHEx_OBGetConfig(&optionBytes); HAL_FLASH_Unlock(); HAL_FLASH_O...
