For further information about direct (pure SPI) in-system programming of SPI Flash memories, please see Xilinx Application Note XAPP951 "Configuring Xilinx FPGAs with SPI Serial Flash".

You must follow the procedure below.

• Make sure S2 is switched to "Reset" (OFF) during programming.
• Connect the host computer to the micromodule through both the SPI flying leads cable and the USB cable.
• Start Xilinx ISE iMPACT. The following example shows the case of iMPACT 9.2. If the "iMPACT Project" window pops up, press the "Cancel" button.

• Double click the "Direct SPI Configuration" option in the "Modes" panel.

• Right click the "Direct SPI Configuration" panel to add a device and select "Add SPI Device".

• You can now select the file corresponding to your device. In the following example, we will show how to select the micromodule reference device "blinking.mcs" in the "TE0300" folder.

• Select the part name corresponding to the SPI flash present on the module (STMicroelectronics M25P32, a 32 Mbit (4M x 8) Serial Flash memory).

• iMPACT should now look like this.

• Right click the SPI PROM device and select the "Program" operation.

• In the "Programming Properties" window, just leave the default settings and press the "OK" button.
• iMPACT will first erase the memory (notice the mismatch between the two progress indicators)
• and then write it (notice the match between the two progress indicators).
• After successful programming, you should read the message "Program Succeeded" popping up for a few seconds in the "Direct SPI Configuration" panel.
• Switch S2 back to the "Run" position. In case you uploaded the test design, you should see the on-board led blinking at 0.5 Hz.
