Note: If no FPGA chip is detected at this time, check whether the adapter of the downloader is tightened, whether the cable is tightly plugged in, and whether the development board is powered on and whether the driver of the downloader is installed correctly.

Double-click the Xilinx chip and open the lcd_test.bit file in the 04_lcd_test directory in the pop-up navigation box.

Select No PDFin the pop-up dialog box for adding SPI FLASH.

Right-click on the chip and select Program to download the Bit file to the development board's FPGA.

flash_sdram_lcd.bit under the 09_VERILOG\18_flash_sdram_lcd directory so that the image stored in the SPI FLASH can be directly displayed on the LCD screen.

Although the development board is configured with the SPI FLASH chip (we use the W25Q128) before leaving the factory, the DEMO factory program is fixed. However, the user erases and programs his own program during use and operation. We can use the following methods: Restore the factory program. The format of thePDFconfiguration file downloaded to the configuration chip is an MCS file. For how to convert the Bit file into an MCS file, refer to the fourth part of the document “Black Gold Sparten6 evelopment Board Verilog Tutorial V1.3.pdf”: Water Lamp Routines. Let us explain how to download the MCS file through the JTAG port to achieve the solidification of the program.

1). The development board is connected to the JTAG downloader and thenpowered on. The Xilinx Impact software is opened. The Initialize Chain establishes the JTAG connection and double-clicks the SPI/BPI icon to add the

MCS file.

2). Select the DEMO_A.mcs file in the 08_DEMO directory and open it.

3). Select the type of SPI FLASH as M25P16. This model needs to be consistent with the SPI FLASH model on the development board.

4). Right-click the FLASH icon and select Program.

5). In the pop-up property box, you can not select Verify in order to speed
