    AX301 User Manual 3.1 JTAG First of all ,we talk about FPGA configuration and debugging interface: JTAG interface. The function of the JTAG interface is to download the compiled program (.sof) to the FPGA or download the FLASH configuration program (.jic) to the SPI FLASH. After the sof file is downloaded to the FPGA, it will be lost after power-off ,so we need to download it again after the power-on.
