Translations:NixOS on ARM/UEFI/51/en

Where supported, Nix can be used to build U-boot from its main-line repositories. See U-Boot#Building a packaged U-Boot for further information. The resulting firmware image can then be flashed to SPI with tools such as flashcp or flashrom, or installed to EMMC/SD card by writing to specific offsets. This is platform specific, refer to upstream U-boot documentation for your platform or board.
