Hello,I'm currently using an STM32F777 MCU with the Keil MDK. I want to run an HTTPS serer on this system, and I set up mbedTLS with Keil's network component (using the TLS_ECDHE_ECDSA_AESGCM128 cipher suite). By default, it takes around 6 seconds fo...
I am trying to run a debug session with the built application which is built upon the secure bootloader. Note: All security mechanisms are disabled for debugging purposes.The issue seems to be the combined elf file. Loading this using a debugger, the...
I worked on POC for X-CUBE-SBSFU in windows environment. It is all working fine without any issues.Now the challenge is, we need to migrate SBSFU source to be compiled in Ubuntu Linux environment. I am struggling to do this, and getting lot of errors...
As per my understanding Secure Mode of STM32H7 as follows:RESET => Enter System Boot loader => Program OB register content => If (SECURITY) => RSS Boot => Configure Secure User Memory => Jump to Secure User memory on User Flash.I have two open questi...

Hi,I want to port "SPI_FullDuplex_ComDMA_Slave" to "TFM_SBSFU_Boot".My MCU is STM32U585.I can port "SPI_FullDuplex_ComDMA_Slave" to "TFM_Appli NonSecure" success, but fail to port it to "TFM_SBSFU_Boot".Do you have any suggestion for it?Please advi...
Hello guys,I'm trying to use the sample project given in the MOOC, and I'm getting compilation errors. The below is the error message.../STM32_Cryptographic/legacy_v3/src/hash/legacy_v3_sha1.c:20:10: fatal error: hash/legacy_v3_sha1.h: No such file o...
The clear_bit macro in the CMSIS driver is causing a warning when used in the function HAL_CRC_DeInit:
I would like to set the security fuse but also have the application start running. I can set the read protection but after that I can no longer communicate with the unit. Likewise I can start the application using the start command -s but after that ...
