-Before erasing the FLASH memory, it is necessary to switch the board to bootloader mode. Hold down the BOOT button (red arrow), press the RESET button (green arrow), wait for 1 second, and release the BOOT button. Then, you can erase the FLASH memory using the ERASE button. After a successful erase, the status will change to FINISH.
