This example is based on the GD32W515P-EVAL-V1.0 board, it provides a description
|
|
of how to erase and program flash memory.
|
|
|
|
In erasing operation, a comparison between flash memory and 0xffffffff is done to
|
|
check whether the flash memory has been correctly erased. If the result is wrong,
|
|
LED1 will be on.
|
|
|
|
In programming operation, a comparison between flash memory and target data is
|
|
done to check whether the flash memory has been correctly programmed. If the result
|
|
is wrong, LED2 will be on.
|
|
|
|
If all the three operations are successful, LED3 will be on.
