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: * [FPGA compatibility list](https://trabucayre.github.io/openFPGALoader/compatibility/fpga.html) * [Board compatibility list](https://trabucayre.github.io/openFPGALoader/compatibility/board.html) * [Cable compatibility list](https://trabucayre.github.io/openFPGALoader/compatibility/cable.html) Also checkout the vendor-specific documentation: [Anlogic](https://trabucayre.github.io/openFPGALoader/vendors/anlogic.html), [Cologne Chip](https://trabucayre.github.io/openFPGALoader/vendors/colognechip.html), [Efinix](https://trabucayre.github.io/openFPGALoader/vendors/efinix.html), [Gowin](https://trabucayre.github.io/openFPGALoader/vendors/gowin.html), [Intel/Altera](https://trabucayre.github.io/openFPGALoader/vendors/intel.html), [Lattice](https://trabucayre.github.io/openFPGALoader/vendors/lattice.html), [Xilinx](https://trabucayre.github.io/openFPGALoader/vendors/xilinx.html). ## Quick Usage `arty` in the example below is one of the many FPGA board configurations listed [here](https://trabucayre.github.io/openFPGALoader/compatibility/board.html). ```bash 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](https://trabucayre.github.io/openFPGALoader/compatibility/cable.html)) instead of the board model: ```bash openFPGALoader -c cmsisdap fpga_bitstream.bit ``` ## Usage ``` Usage: ./openFPGALoader [OPTION...] BIT_FILE openFPGALoader -- a program to flash FPGA --altsetting arg DFU interface altsetting (only for DFU mode) --bitstream arg bitstream -b, --board arg board name, may be used instead of cable -c, --cable arg jtag interface --vid arg probe Vendor ID --pid arg probe Product ID --ftdi-serial arg FTDI chip serial number --ftdi-channel arg FTDI chip channel number (channels 0-3 map to A-D) -d, --device arg device to use (/dev/ttyUSBx) --detect detect FPGA --dfu DFU mode --dump-flash Dump flash mode --external-flash select ext flash for device with internal and external storage --file-size arg provides size in Byte to dump, must be used with dump-flash --file-type arg provides file type instead of let's deduced by using extension --flash-sector arg flash sector (Lattice parts only) --fpga-part arg fpga model flavor + package --freq arg jtag frequency (Hz) -f, --write-flash write bitstream in flash (default: false) --index-chain arg device index in JTAG-chain --list-boards list all supported boards --list-cables list all supported cables --list-fpga list all supported FPGA -m, --write-sram write bitstream in SRAM (default: true) -o, --offset arg start offset in EEPROM --pins arg pin config (only for ft232R) TDI:TDO:TCK:TMS --probe-firmware arg firmware for JTAG probe (usbBlasterII) --protect-flash arg protect SPI flash area --quiet Produce quiet output (no progress bar) -r, --reset reset FPGA after operations --spi SPI mode (only for FTDI in serial mode) --unprotect-flash Unprotect flash blocks -v, --verbose Produce verbose output --verbose-level arg verbose level -1: quiet, 0: normal, 1:verbose, 2:debug -h, --help Give this help list --verify Verify write operation (SPI Flash only) -V, --Version Print program version Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
