Jlink semihost issue

Vandarkholme — Fri, 19 Jul 2024 06:18:29 GMT

hello! I'm use printf function to print message on console, but not worked. My debugger is Jlink V9, here is my project settings:

So, is there anyway to print messages on s32ds console? Or only use uart/RTT?

Hi @Vandarkholme,

Please enable semihosting by declaring and calling initialise_monitor_handles().

#include "Mcal.h" #include "stdio.h" volatile int exit_code = 0; int counter, limit_value = 1000000; extern void initialise_monitor_handles(void); int main(void) { initialise_monitor_handles(); for(;;) { counter++; if(counter >= limit_value) { counter = 0; printf("Hello World\n"); } } return exit_code; }

Also, make sure that a library that supports semihosting is configured:

Best regards,
Julián
