Hi Feilpe

I found the "task_sleep()" function in legacy.h, When I add the "task_sleep(500)" and the include file legacy.h, the compiler tell:
    undefined reference to `_legacy_sleep'

I am confused.

Thanks

Hi, depending on where the message is placed, you will not see it on console.

if I remember the hw example in zephyr was implemented on whis way:

void main(void)
{
   printf("Hello_x86! \r");
}

Instead, do a slight modification on main.c on main function to become:


void main(void)
{
   for(;;) { 

          printf("Hello_x86! \r");
          task_sleep(500);
   }
}

This will continuosly prints the message on your console, and if your def_config is okay, you will able to see the messages hitting
on your minicom instance.

Best,

Felipe

If you just use printf() you will get strings outputted to serial with most default configurations.
