I try to understand in details the way the Hash peripheral works on the STM32L552. I need to make the HASH SHA-256 with 224 blocks of 512 bits. The Hash works perfectly until the block 223. Then I enter 16 values in the FIFO (in my code below I have ...
Hello.I'm working with STM32H573.I have a question related with the use of STSAFE-A110 for TLS. I have to authenticate also the client.I've succeded stablishing TLS mutual authentication with HTTPS server and TCP server (different applications, not ...
HiI am implementing the ECDSA-P256 signing for a payload.I have checked the example code https://github.com/STMicroelectronics/STM32CubeU3/tree/main/Projects/NUCLEO-U385RG-Q/Examples/CCB/CCB_Protected_ECDSA_SignatureThe example code shows that the s...
STM32 H573 TrustZone Enabled question. I'm executing the STM32 H573 example for TrustZone Enabled (OEMiROT, Secure, and Non Secure Apps). I know the OEMiROT and Non Secure App prints out and logs info, but I want to be able to do that in the Secure ...
Hi teams,CPU: STM32U0Current RDP level: Level 1OEM1 RDP lock: Enabled.I had set the 128bit OEM1 key to the OEM key registers [FLASH_OEM1KEYWyR ]accordingly, and the written OEM1 key values was verified using their CRC values by reading OEM1KEYCRC r...
Hi, I am working with the SBSFU_Boot on the STM32U5A9 chip. After the SBSFU_Loader has written the update image into internal memory, a reset happens in order for the SBSFU_Boot to write the image to be booted. When performing the update, it ends up ...
