)
Power supply jumper J23. If you are using an external power supply
interface, use a jumper cap to connect the two jumpers "EXT_5V" and
"PWR_5V". If you are using the "CPU_TAG" interface to supply power,
please connect "USB_5V" and "PWR_5V". As shown below:

Part of the FPGA BANK voltage is determined by selection jumpers J9, J10.
Voltage of BANK34 and BANK35 in development board, in order to adapt
to a variety of external signals, is adjustable power supply, specifically by
two common voltage options, 1.8V and 3.3V. Before the development
board works, please make sure that the jumpers of J9 and J10 are
connected. By default, you will be connected to 3.3V. As shown below:
