[edit] Procedure
- You need a JTAG cable supported by the Xilinx tools.
- Download and install ISE Webpack from the Xilinx website (free of charge, but registration required).
- Download the binary kit, unpack it and cd to the directory where the MCS files are.
- Run impact -batch and enter the commands below. Flashing takes several minutes.
- Power cycle the board. It should boot!
- There is a development project going on in order to do it without the expensive Xilinx cables and the bloated (multi-GB) and proprietary Xilinx tools. Check the mailing list archives for more info.
