1. FPGA SRAM Download Mode:

Plug the USB cable to the USB interface (J2) on the development

board. Power on, then 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 (J2) on the development

board, then power on. Open the Programmer, select External Flash

mode, and then select the bitstream file and FLASH you required. Turn

off the power after downloading. Power on, and then the device will

import the bitstream file to SRAM from the external Flash.
