Patch flash sector size #7

Closed GSunwinder closed 8 months ago

GSunwinder commented 8 months ago

After some number success of writes in flash MCU another download fails with error. But, if execute download with flash sector size = 1024 bytes recording capability is restored. Possibly an error in reference manual (flash sector size) or bug of bootloader.

The flash sector size is 1024 all the other MCU I tested, I think there is a difference between the sector size used by the bootloader to erase flash and the actual MCU capacity (flash controller supports different erase size).
