## What it is
openFPGALoader is a universal open-source command-line utility for programming FPGAs. It supports loading bitstreams into SRAM or writing them to flash across many boards, cables, and FPGA families from major manufacturers such as Xilinx, Intel/Altera, Lattice, Gowin, Efinix, Anlogic, and Cologne Chip.

## Use cases
- load a bitstream onto an FPGA board from the command line
- write a bitstream to FPGA configuration flash memory
- program Xilinx, Lattice, Gowin, or Intel FPGAs without vendor tools
- flash an Arty board or other supported dev board
- configure FPGAs on Linux, macOS, Windows, or OpenBSD
- automate FPGA programming in CI or build scripts

## When to choose
- you want a single open-source tool instead of multiple vendor programming utilities
- your board, cable, or FPGA is on its compatibility lists
- you need cross-platform FPGA programming from the terminal or in automation

## When to avoid
- your specific FPGA, board, or debug cable is not supported
- you require vendor-specific features only available in proprietary tools like Vivado Hardware Manager

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, developer-tools, embedded
- domain: embedded-systems, hardware, developer-tools
- platform: windows, bsd, cli, cross-platform
- tags: fpga, bitstream, jtag, xilinx, lattice, gowin, intel-altera, efinix, anlogic, cologne-chip, flash-programming, command-line, linux, macos
