$ sudo dd if=$buildInputs/u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8 The easy way
Porting NixOS to new boards The easiest wayĪssuming upstream U-Boot supports the board through a defconfig, it is possible possible to build U-Boot using the cross-compiling architecture from an x86_64 host. Details for what the boards support in relationship to the boot process are detailed in their respective pages. However, support for input or display devices varies greatly, depending on the board. U-Boot also provides an interactive shell and the generation selection menu (just like GRUB). The partition needs to have its "bootable" flag set. For a quick TL DR about the generic distro configuration support: U-Boot is scripted to scan all attached storage devices & partitions and look for a file named /extlinux/nf or /boot/extlinux/nf (which will be generated by NixOS, just like /boot/grub/grub.cfg is generated on PCs). NixOS uses U-Boot's Generic Distro Configuration Concept as the mechanism to communicate boot information (such as path to kernel zImage, initrd, DTB, command line arguments). On NixOS, all ARM boards are expected to use U-Boot as the firmware and bootloader. Note: Instructions removed since they referred to a long abandoned user-provided cache. It is only for building the installation image! Note: the default configuration.nix will contain something like imports = do not include that in your final installation or you will experience interesting problems. To help with the SD card installation method, the boot scripts on the image automatically resize the rootfs partition to fit the SD card on the first boot. Using this installation method is strongly recommended, though if you know exactly what you're doing and how U-Boot on your board works, you can use nixos-install as usual. The image is designed such that it's possible to directly reuse the SD image's partition layout and "install" NixOS on the very same SD card by simply replacing the default configuration.nix and running nixos-rebuild.

The installation image is actually a MBR partition table plus two partitions a FAT16 /boot and a ext4 root filesystem. (Discuss in Talk:NixOS on ARM#) Once the page has been updated this notice can be removed. Only the board specific page should make recommendations about the kernel. This section should be rewritten to be generic and refer people to the board-specific page. Reason: The kernel version recommendations of this section are severely outdated. That way you not necessarily have to have a HDMI Display and keyboard.

The base images are configured to boot up with a serial TTY ( RX/TX UART ) 115200 Baud. img files can be directly written to a microSD/SD card (minimal recommended size: 4 GB) using dd, once uncompressed from the ZSTD container. zst, it will need to be decompressed before writing to installation device.
