Hi, I've been tinkering around with the LattePanda Alpha and I'm wondering if there is a way to get an external LED working over GPIO that activates when either the OS is loaded, or when power is running to the CPU.

I've got the LED working using a blink scheme in Arduino, but the problem is that the light turns on as soon as the board is plugged in. I would prefer to have the light activated when power is going to the CPU.

What would be the best way to get this working. Essentially, I want it to run just like the POWER LED (not d13) on the board.
