MSP430FR2355: attempting some debugging using console with printf?

Steve Wenner

Part Number: MSP430FR2355


Hello...

I have the following code in main.c

    if (ERR_FUNC_RTN == init_UART(&applicationUART))
            printf("ERROR\n");

I have stdio.h included....

When I run the application with faulty parameters and get to this statement my code halts in trgmsg.c at

    for (i = 0; i < length; i++) PACKCHAR(*data++, p, i+8);

Even without any breakpoints....If I hit the run button to continue the print works.  I have adjusted heap and stack to 400...Can someone tell me how to get around not having the program halt and having to "re" hit the run button?

Using CCS 10.4.0

    Hi Steve,

    The issue you are having sounds like the one reported in this thread. Unfortunately, I don't believe there is a fix for this issue.

    In general, I avoid printf on these systems since is a resource heavy function. You can try using the backchannel UART if you want to have a textual debug console. Of course this is more work for you to implement. 

    Regards,

    Evan
