MSPM0G3507: debug log to CIO console with GCC compiler

toby
Prodigy 40 points

Part Number: MSPM0G3507

Hi,

I would appreciate it if an empty example (project) were available to write debug text to the CIO console using printf...

I tried it with an empty project from the wizard and the TI compiler. That works.

However, attempts with `-heap_size=512` etc., as discussed in various threads, do not help. What parameters must be available to GCC for the output to be sent to the CIO?

CCS 20.4.0.13 

Thanks for any support!

    Did you try to increase the stack size?

    If I try to change the stack or heap size, I got an error at building.

    Adding heap_size=0x400 to the GNU linker command:

    #include "ti_msp_dl_config.h"
#include <stdio.h>

int main(void)
{
    SYSCFG_DL_init();
    fflush(stdout);
    printf("Hello world\n");
    fflush(stdout);
    while (1) {
    }
}

    In the project settings, there isn't a special stack or heap size input field to edit (like using TI compiler...).
