Software Reset the 101

Hardware Arduino 101

You can try with this. I don't know if this will work or not because I don't have the 101, but I found this code in the source of the 101 RTOS.

void reboot(void){
  SCSS_REG_VAL(SCSS_SS_CFG) |= ARC_HALT_REQ_A;
  SCSS_REG_VAL(SCSS_RSTC) = RSTC_WARM_RESET;
}
