Hello,I am working with SBSFU on a STM32U575 microcontroller and have written a function to check the cause of the system reset by reading the flags from the RCC registers using __HAL_RCC_GET_FLAG. However, the issue is that none of the RCC register ...

Hi,I am working with SBSFU on a STM32U575 microcontroller, and I want to use the __attribute__((section(‘.ram2’))) to place a variable in the secure SRAM2 memory section so that the variable can write to it. However, the secure SRAM2 memory is reset ...

Hi,I am implementing the sbsfu encryption functionality on the stm32u575 micros which do not contain hardware accelerator. For this I have decided to use x-cube cryptolib to be able to encrypt and decrypt messages. I have tested the example aes_cbc_e...

HiI am using the SBSFU application on the stm32u585 board and I am trying to use the crypto library as explained in the CRYP_SAES_ECB_CBC example but the error_handler is triggered when the MX_SAES_AES_Init is initialized.Any help?

Hello,I would like to be able to debug the SBSFU application of the STM32U5 microcontroller series. What steps do I have to follow to be able to do it? Thanks in advance

Hello @Jocelyn RICARD , I know that the register will not going to be one but using the following function that I’ve implemented to read the reset flags from both PWR and RCC registers to determine the cause of a system reset. However, every time I r...

Hello,I made a mistake with the memory address which was SRAM3 0x30040000 with 0x300D0000. With 0x30040000 it works perfectly.

Hello @Jocelyn RICARD,I have made the changes and modified all the partitions so that the SRAM3 address, in my case 0x300D0000, is Non-Secure Callable, allowing me to write from secure_nsc. However, when I attempt to write to or read from the SRAM3 a...

Hello @Jocelyn RICARD,If I use another memory in the secure zone SRAM1 for example to be able to write using the __attribute__((section(‘.ram'))) I would have to modify the linker script right? how should I modify it?

Hello @Jocelyn RICARD,Yes, that's what I wanted to say. I have implemented crypto in my application but it is not encrypting well.I'm sorry I wrote quickly and I didn't realise that the sentence didn't make sense.
