The Issue When my bootloader jumps to the application all `AES_ECB_Encrypt_XXX` incorrectly encrypt/decrypt the data. Once the application fails to initialize too many times it will reboot due to watchdog and the ncrypt/decrypt will continue to fail ...
Hello all,Another question from SBSFU series.I'm wondering what are the available ways to clear option bytes?The option I was using so far was simply STM32CubeProgrammer GUI, but what if we don't have ST-Link on board and we have to rely on something...
Hi, need support. send_msg() is a secure area message of TF-M and I am calling it in non secure area via secure_nsc API.What I am observing here is that I am not able to call this function in _tx_initialize_kernel_enter() function after the call to T...
