      when execute this two command it will erase the P-Flash code, If it's erased, isn't it that the application won't run? Need to download the app again。

Hi kui wu,

If it's erased, the MCU is blank no application run. The reset pin will toggle. Need to download the app again.

Best Regards,

Robin
