Do all the STM32WL series MCUs support STSAFE ? If yes, how it can be done?
Hi,is there a possibility to do the complete chain to product state "closed" by non secure user code ?I have a custom bootloader which usually did a set of the old RDP Level.Now, with a STM32H57 device we have to use the new product state. I'm able t...

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, n...
I am using mbedtls module to verify the signature of firmware using RSA and its giving MBEDTLS_ERR_PK_INVALID_PUBKEY after parsing the public key. I am using OpenSSL for generating public and private keys the public key is generated using openssl gen...
Hi, I am using ADC1 on stm32H563ZI nucleo board with trustzone enabled, I am not getting proper adc values (getting adc count of 822). When trust zone is disabled I am getting proper value of around 4095 with input of 3.3Volt .I am attaching the proj...
