AVRMega can't switch two threads

Now, I detect when program execute function chVTResetI(). After execute that my program will auto reset and run again from start of main function.

Without seeing your code it is hard to give meaningful advice. Has the virtual timer been initialized?

Yes, I initialized virtual timer already.

Code: Select all

msg_t chSchGoSleepTimeoutS(tstate_t newstate, systime_t time) {

  chDbgCheckClassS();

  if (TIME_INFINITE != time) {
    VirtualTimer vt;

    chVTSetI(&vt, time, wakeup, currp);
    chSchGoSleepS(newstate);
    if (chVTIsArmedI(&vt))
      chVTResetI(&vt);
  }
  else
    chSchGoSleepS(newstate);
  return currp->p_u.rdymsg;         << After execute this instruction
}

When my program execute last instruction (return value) of funnction chSchGoSleepTimeoutS(), then my program will exit this function and reset itself.

I try many times for checking it.

Does "currp" contain a meaningful value? (it should be pointing to the current thread).

Without more context I can't help.

Now, I don't have source code. I will send it tomorrow.
