Hello,

On our *NIOS* development boards (not UP3), the "cf_power" pin in the hardware example designs goes to a small mosfet on the board which turns power to the CF socket on/off. It acts as a "power switch".

I do not know how the UP3 board is designed for this; you should carefully study the board schematic to see how things are setup, and change the design accordingly if things are different.
