Status
The board boots NixOS from eMMC and will also load NixOS via its integrated microSD reader.
The official documentation, which is comprehensive, can be found on the FriendlyElec wiki.
U-Boot for this board is not entirely open, incorporating a binary blob for the tertiary program loader (TPL). Compilation instructions are featured in section 15.7 of the FriendlyElec wiki, and a build target is also provided in upstream u-boot (nanopc-t4-rk3399_defconfig).
Pre-built u-boot images are available here.
== Board Specific Installation Notes
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.
