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

Part Number: MSP430FR2311
Other Parts Discussed in Thread: MSP-EXP430FR2311

Tool/software:

I am testing the sample program msp430fr231x_WDT_01.c compiled with CCS12.7.1 using MSP-EXP430FR2311, but it does not access the Watchdog Timer interrupt service routine.

1: The program is

// Darren Lu

// Texas Instruments Inc.

// July 2015

// Built with IAR Embedded Workbench v6.30 & Code Composer Studio v6.1 and is likely to have been tested.

2: The problem cannot be solved even with the latest CCS 12.7.1 compiler.

3: Since it is MSP-EXP430FR2311, it is difficult to suspect the hardware.

Do you know any good solutions?

    Hi,

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

    Regards,

    Zoey

    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?

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

    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.

    2024/6/7 16:17   I found that when I tested it after completely disconnecting it from the CCS, it worked properly. I don't know why it didn't work when the CCS was connected. However, it did achieve its purpose. Thank you for all your advice.
