In BOXER-8250AI there are two connectors that are not specified on datasheet
We need to use a GPIO to generate a digital signal to create a watchdog to keep the system running at any cost.
We already have a external control board responsible to power on, power off and listen the watchdog signal.
Does anyone know what is the function of connectors CN23 and CN21 on base board?
CN21 is for RD debug use only.
CN23 is a GPIO pin, but our 8250 does not have this function in the specification, so we do not have the corresponding cable and sample code available.
