1.
FPGA SRAM Download Mode:
Plug the USB cable to the USB interface (J26) on the development
board. Power on. Open the Programmer, select SRAM mode, and then
select the bitstream file you required.
2.
FPGA MSPI Download Mode:
Plug the USB cable to the USB interface (J26) on the development
board. Set J13 to "0", and set J9 and J10 to "1". Power on. Open the
Programmer, select External Flash mode, and then select the bitstream
file you required. Turn off the power after downloading. Set J13, J9,
and J10 to "0", power on, and then the device will import the bitstream
file to SRAM from the external Flash.

Overview
DC5V is input by USB interface. The TI LDO power supply chip is used
to step down voltage from 5V to 3.3V, 1.8V and 1.0V, which can meet the
power demand of the development board.
