Hello everybody,after a long fight I got the SDMMC2 interface running in 1 bit mode on the STM32H755. I thought running it in 4 bit mode in the next step should be no big deal anymore; what a naive assumption...The SDMMC is running with FATFS and FRE...
Hi,I'm not sure what is going on exactly, but I think there is either an issue with the HAL or the USB windows driver for STM32 CDC. I am using an STM32L072KBU, STM32Cube MCU Package 1.17.0. I wait until the device is enumerated (by checking the dev_...

Hello, I a new with NUCLEO STM32H753ZI and trying the SBSFU examples (1 and 2 images). I can flash and launch the SBSFU but I can't load any user application (userapp.sfb)I use STM32 tools, either using Linux or Windows with the same result :I conne...
Hi all,I am practicing the Secure boot using SBSFU using the stm32L476 development board. I have implemented a code for the SBSFU, but it is giving a warning WARNING: A Reboot has been triggered by a Watchdog reset! INFO: Last execution detec...
I'm working on creating a sfu loader to load sfb files from an external flash on a port I made for the STM32H735 (based on NUCLEO-H753ZI)I follow the same steps as used in the ymodem loader:read and verify header (reusing SFU_LOADER_VerifyFwHeader)er...
For the past few weeks I have been trying to port the NUCLEO-H753ZI SBSFU implementation to the H757 and have run into several problems. My development environment is linux.First of all, I could not build the binaries succesfully without massive modi...
Hi all,I'm working in a project (with STM32L476) in which i am building my own bootloader to perform secure boot and firmware upgrade.I have some doubt regarding this matter. is there any resources available for secure the HEX file (encrypt and decry...
I'm following the security part 6 - 02 Building the SBSFU but the final build of the UserApp always ends up with an error.Instructions are being followed EXACTLY as in the video. I'm getting a different project size when building the SBSFU, slightly ...
I have external flash of size 1MB. I want to explore the possibility of having encrypted code of size 500kb in external memory and run it through OTFDEC feature of STM32L562QE.From the reference manual I saw that provision of 4 different OTFDEC regio...
