The NanoPC-T4 is a single board computer built around the Rockchip RK3399 SoC.
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.
