Hi, I have enabled 'watchdog' in u-boot using flag 'CONFIG_WATCHDOG'. I wonder how the 'watchdog' gets reset when the cursor is waiting for user input. As per my understanding the 'WATCHDOG_RESET()' gets called in 'readline()' prior calling 'getc()'. In our case, the 'getc()' has been mapped to 'serial_getc_dev()' of 'cpu/ppc4xx/serial.c'. The code of 'serial_getc_dev()' executes in continous loop till user presses a key. The good thing is that the boad doesn't get reboot even if user doesn't enter any key. In 'serial_getc_dev()', I don't see any call to reset the watchdog . Can you help me to find out the how Watchdog is taken care (gets reset) whicle executing a infinite loop (if user doesn't press any key) ? ( Note: I am not using 'CONFIG_HW_WATCHDOG' flag) Regards, Sachin Rane
