Hello, Having an issue with STM32G031K6Ux MCU. Below added function that checks Options bytes, and if needed - makes changes (power re-cycle is needed after it).This function CheckOptionBytes() works OK on several MCU's. But on this MCU we have an is...
I have a problem with erasing sector 0 in Bank 1 of a stm32h7 CPU. See my code snipped below...When I run the code in the debugger, the CPU never returns from the call to HAL_FLASHEx_Erase. When I interrupt the programm the PC is set to 0xFFFFFFFE wh...
The size of system memory on STM32H743 is 2 sectors of 128KB each.What is the size of the option bytes block?
I am using STM32L562E-DK.I have ported SBSBFU for it. It is working fine. I want to store my custom data into internal flash and read it on bootup time in the bootloader.For testing I am flashing one binary of 16 byte which's content is "Hello World!...
Hi,I want to block flash memory for writng after programming it. It is important that write protect should not be possible to deassert. I have read about RDP mechanism, but there is information that on level 2 write protection is permament, but only ...
Hi,in https://www.st.com/resource/en/programming_manual/cd00283419-stm32f10xxx-flash-memory-microcontrollers-stmicroelectronics.pdf section 2.4.1 it says that, for connectivity line devices (like the STM32F105RC I'm using), pages 0-1 are automaticall...
I have a bootloader that attempts to verify the integrity of an application image before it transfers execution to the application. It does this by performing a CRC (using software) on the image. However, if the internal flash is corrupted somewhere ...
Currently, i working on the nucleo-L552zeq and i run the SBSFU exemple propose by the cubeL5. i use the script regression.sh and the script the SBSFU_UPDATE.sh to initialize the board and download the firmware. this example can work normally on the b...
Hi there,I am trying to understand the state of the option byte values in flash after a forced mass erase (changing RDP from level 1 to 0) for a STM32L151 (Cat.2).From my own investigation it appears that after a forced mass erase all the option byte...
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...
