Hello STM32U5 community,I was making a few attemps with my B-U585I-IOT02A demo board and TF-M. I am afraid I have irreversibly locked the MCU.Here is what I did:run regression.shset RDP level 1 with the Programmer despite the warnings, because I forg...
On switching from secure to non-secure mode using a function pointer (with the cmse_nonsecure_call attribute) in STM32L562(ARM Cortex M33), general purpose registers R0-R4, R12 and floating point registers S0-S15 are not restored when back in secure ...
Hi ST Team,I'm working on a project where I'm using SBSFU as bootloader (on a STM32H7). When I download the new firmware image, SBSFU reboot the system and start execution (decrypting image, validating and so on...). While SBSFU is doing these action...
Hi,I am working on enabling hardware cryptography in nucleo-u585ai board.Can you suggest an example for enabling hardware cryptography? or Is it enabled always?How to test or know that data is encrypted?Thanks,Akanksha
Hello,A hard fault exception is being thrown when I flash the SBSFU_userapp.bin file with the STM32Cube Programmer to device that uses the WB55 MCU architecture (M4/M0+) and then try to run the SBSFU example in Tera Term. The secure engine is first i...
Hi,Where can I find how the protection against DPA attacks implemented in the STM32U585 microcontroller works?I couldn't find anything in the datasheet and reference manual.Thanks
In my application, I have a sequence which looks something like this:Load an AES key from CKS using SHCI_C2_FUS_LoadUsrKeyCall HAL_Cryp_Init, HAL_Cryp_Decrypt, and HAL_Cryp_DeInit to decrypt a block of dataUnload the key from CKS using SHCI_C2_FUS_Un...
In some ST documents the STM32L0X1 is listed as having an RNG peripheral and older versions of the CMSIS headers list the RNG register addresses. Moreover, enabling the peripheral and using it appears to generate random numbers. However newer manual...
Hi,I'm using some STM32 drivers code to parse X509 certificates. These drivers are based on ECC cryptography. I need to change to RSA. I need utilities such as parseCert()isValidCert()isParent()which exist for ECC, but I cannot find any equivalents f...
