Connect nRST Pin to 5 V

Hi, i want to use the nRST Pin (CW Lite) to short circuit the power of my target directly in order to force a reset/reboot of my target. I may cut the usb cable and connect there the +5V to nRST. Is it possible to use this pin for this? Maybe i should insert a series resistor between the +5V and the nRST to reduce the current.

Thanks and best regards


Do not use the nRST pin to pull a power line low like that, as you will destroy the nRST output driver and likely cause other damage to the FPGA. One way you could control a 5V rail like that is by using a relay. You could control the relay via a transistor and the transistor via the nRST pin.
