ML50x Demonstrations in SPI Flash
SPI Flash memory can be used for FPGA configuration or to hold user data. The SPI Flash
on the ML50x board contains the following bitstreams:
• “SPI Flash Hello Demonstration”
• “My Own SPI Flash Image Demonstration”
To select configuration using SPI Flash, set the configuration address and mode DIP switch
(8-position DIP switch) to 00000101.
SPI Flash Hello Demonstration
Location
SPI Flash configuration address 0.
Description
This program displays to the character LCD the “Design Loaded Using SPI Mem”
message.
Setup
Press the Prog button to see the “Design Loaded Using SPI Mem” message displayed on
the character LCD.
My Own SPI Flash Image Demonstration
SPI is a flash device that can store your configuration file and program it to the FPGA. This
demonstration shows you how to store your own design into the SPI Flash and how to
program it onto the FPGA. This exercise overwrites the contents of the SPI Flash.
1. Disconnect the cable attached to header J1 (the header on the left side of the board)
from the Xilinx download cable.
2. Connect JTAG flying wires from the Xilinx download cable to the J2 header using the
pin labels as a guide on how to make the connections. The 7-pin J2 header is located to
the right of the FPGA and just above the LCD panel.
3. Set the configuration address DIP switches to 00010101.
4. Remove the inserted ML50x CF card if present, and press the Prog button to erase the
FPGA.
5. Open a DOS command shell. Click Start Menu → Run, then enter cmd as the program
to run, and click OK.
6. Change directory to your lab directory. Type cd <LAB_DIR>.
7. Copy your BIT file into this folder.
Copy <file_name>.bit .
8. Format the BIT file to an MCS file.
promgen -spi -p mcs -o <file>.mcs -s 16384 -u 0 <file>.bit
9. Launch iMPACT and double- click Direct SPI Configuration in the iMPACT Modes
window to program the SPI Flash device.
10. Right-click the Direct SPI Configuration tab and select Add SPI Device...
