- Tue Nov 15, 2016 4:52 pm #58192 So I have a fairly large application running on the RTOS SDK and that needs some serious debugging due to some exceptions.
And I started using GDBStub.
My application starts and run successfully without the call to gdbstub_init, but when calling gdbstub_init in user_init, the application crashes at startup and wont even start.

I therefore made a simple application as the one below and still the same thing happened when gdbstub_init is called in user_init. LED blinks when not called.

The UART log is this

And the code is this

Code: Select allvoid FOO(){
   static uint8_t v;
   GPIO_OUTPUT_SET(2, (v&1));
   printf(v&1?"ON\r\n":"OFF\r\n");
   v++;
}

void user_init(void){
   static os_timer_t ledTimer;
   uart_div_modify(0, UART_CLK_FREQ / 115200);
   os_timer_disarm(&ledTimer);
   os_timer_setfn(&ledTimer, &FOO, NULL);
   os_timer_arm(&ledTimer, 1000, TRUE);
   gdbstub_init();
}
