STM32H7S78-DK - Error: failed to erase memory

namankumar1992 · ‎2025-04-23

I am using STM32CubeIDE to program my board i.e. STM32H7S78-DK. My file size is in large due to which it is flashing in external flash at address 0x70000000. In case of smaller file size i.e. less than 64 KB, it flashes in internal flash at address 0x08000000. The flashing was working fine in internal as well as external flash. But, all of a sudden, I am getting below error log.
