[ECOS] Is main() a normal thread ?

[Claudio Leonel <cls at elaxys dot com dot br>]

Hi all,

I thought main() was a normal thread but if I ran the
following application step by step in gdb there is no
return from the function cyg_thread_delay(). Apparently
it hangs in the call to cyg_thread_delay().

int main(void) {
   while (1) {
     cyg_thread_delay(100);
   }
}



But if I start a thread from cyg_user_start() I can
single step through cyg_thread_delay() in thread funcT1():

cyg_thread   thread_s;
char         stack[4096];
cyg_handle_t hThread;

void funcT1(cyg_addrword_t data) {
  while (1) {
    cyg_thread_delay(100);
  }
}

void cyg_user_start(void) {
   cyg_thread_create(4, funcT1, 0, "T1",
      (void *)stack, 4096, &hThread, &thread_s);
   cyg_thread_resume(hThread);
}
------------------------------------------------------

Is this the normal behaviour or is there something wrong
with my configuration ?
