openFPGALoader
First steps • Install • Troubleshooting • Advanced usage
Universal utility for programming FPGAs. Compatible with many boards, cables and FPGA from major manufacturers (Xilinx, Altera/Intel, Lattice, Gowin, Efinix, Anlogic, Cologne Chip). openFPGALoader works on Linux, Windows and macOS.
Not sure if your hardware is supported? Check the hardware compatibility lists:
Also checkout the vendor-specific documentation: Anlogic, Cologne Chip, Efinix, Gowin, Intel/Altera, Lattice, Xilinx.
Quick Usage
arty
in the example below is one of the many FPGA board configurations listed here.
openFPGALoader -b arty arty_bitstream.bit # Loading in SRAM
openFPGALoader -b arty -f arty_bitstream.bit # Writing in flash
You can also specify a JTAG cable model (complete list here) instead of the board model:
openFPGALoader -c cmsisdap fpga_bitstream.bit
