MSP430FR2311: The sample program msp430fr231x_WDT_01.c does not work properly on MSP-EXP430FR2311

Hi,

I have tested the code with MSP-EXP430FR2311. It is workable, can you change the EVM and have a try.

Regards,

Thank you for your advice. I didn't expect a problem with the board because it works fine with other software. Since it worked with the board you have, I will order a new board right away and check it when it arrives.

How do you tell that the ISR isn't called? Breakpoint? LED?

 => P1OUT ^= BIT0; 　　// Toggle P1.0 (LED)
=>  Insert it into the area to be tested and use an oscilloscope to check the state of P1.0.

If you pause in the debugger, where is the program executing?

=>  The program is written and run without using a debugger.

The simplest method is the most reliable, so I tested the MSP-Exp430Fr2311 board alone by connecting an oscilloscope to the output. Since it is ROMized, this is the simplest test.
