== Board Specific Installation Notes ==

=== Installation onto eMMC ===

The NanoPC-T4 reserves space for u-boot at the beginning of its eMMC and/or microSD. As a result, successful image installation relies upon a custom partitioning scheme.

==== boot and rootfs ====

The latest linux kernel is working with this board. Instead of building the image yourself you can fetch the latest sd-image from hydra and dd the created images onto the separate partitions.

You can find all the successful builds in [https://hydra.nixos.org/job/nixos/release-18.09-aarch64/nixos.sd_image.aarch64-linux hydra @ nixos:release-18.09-aarch64:nixos.sd_image.aarch64-linux]
