Hi
I am using STM32L4R9ZI for my product and I am facing an issue in updating Flash. I am using flash_l4.c as provided by CubeIDE Project along with the STWIN Kit. I have attached the flash_l4.c for reference. I am using the FLASH_update() function to write data on Flash. Sometimes HAL_FLASHEx_Erase returns an error and the function bails out. Upon the second try the board gets stuck and watchdog happens. Upon the rest, when I try to read the content of Flash on that page it is all empty (i.e 0xFFFFFFFF) on that page.
- Can anyone clarify to me how the page got erased when HAL_FLASHEx_Erase() was unsuccessful?
- How I can resolve this issue in case of Failure as my second retry for FLASH_update() freezes the board? Most of the time I never face this issue.
Any help is appreciated.
