msp430F548A cannot execute program after power off and then on [Copy link]

After using the burning software to download the program into the MCU, the MCU can execute the program normally. After power failure, the MCU will not have any operation after power failure. However, after reopening the downloader, there is an automatic execution option, and then the MCU will re-execute the program at the last power failure.

Pressing reset does not respond

When checking, the power is turned off and then on again. The program is in the MCU, but the MCU cannot execute it by itself. The program can only be executed through the automatic execution option of the downloader.
