openFPGALoader

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, macOS and OpenBSD.

Not sure if your hardware is supported? Check the hardware compatibility lists:

• FPGA compatibility list
• Board compatibility list
• Cable compatibility list

Also checkout the vendor-specific documentation: Anlogic, Cologne Chip, Efinix, Gowin, Intel/Altera, Lattice, Xilinx.

OpenFPGALoader has a dedicated channel: #openFPGALoader at libera.chat.

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

Usage

…

By default spiOverJtag are search into ${CMAKE_INSTALL_FULL_DATAROOTDIR} (/usr/local/share/ by default). It's possible to change this behaviour by using an environment variable:

export OPENFPGALOADER_SOJ_DIR=/somewhere
openFPGALoader xxxx

or

OPENFPGALOADER_SOJ_DIR=/somewhere openFPGALoader xxxx

OPENFPGALOADER_SOJ_DIR must point to directory containing spiOverJtag bitstreams.
