The support varies depending on the architecture and the specific boards. The way the ARM integration is built into NixOS is by making generic builds the first-class citizens; as soon as there is upstream support for the board in the kernel and the bootloader, NixOS should work once updated to these versions. It is still possible, when needed, to build and use a customised bootloader and kernel for specific boards<sup>[[Talk:NixOS_on_ARM#NixOS_.22support.22_for_board-specific_kernels_or_bootloaders|[reference needed]]]</sup>. At this moment in time (early 2018) only AArch64 is planned for full support upstream. Though, neither armv6l or armv7l are being ignored, fixes are worked on and approved as needed; what's missing is support and upstream builds being maintained in binary form. | The support varies depending on the architecture and the specific boards.

=== Getting the installer === | |||
The most current installation images and miscellaneous boot files for ARM devices are currently built maintained and hosted by '''@dezgeg''' at http://nixos-arm.dezgeg.me/installer. Generic usage is described in this page, and board-specific instructions when needed are described on their page. | |||
=== Installation steps === | |||
The installation images come in two flavors: <code>sd-image-armv6l-linux.img</code> is built for the ARMv6 architecture and it comes with the Raspberry Pi kernel. sd-image-armv7l-linux.img is built for the ARMv7 architecture and comes with the mainline multiplatform ARMv7 kernel (multi_v7_defconfig). Make sure you download the correct image for your board! | The installation images come in two flavors: <code>sd-image-armv6l-linux.img</code> is built for the ARMv6 architecture and it comes with the Raspberry Pi kernel. sd-image-armv7l-linux.img is built for the ARMv7 architecture and comes with the mainline multiplatform ARMv7 kernel (multi_v7_defconfig).

The base images are configured to boot up with a serial TTY ( RX/TX UART ) @ 115200 Baud. 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.
