h96-max-v58-nixos

This repository is for my own research, development and bringup of the H96 Max V58. Eventual support may be added to nixos-hardware depending on time and interest.

Usage

1. Get the device into maskrom or loader mode
2. nix build .#h96-max-v58-image
3. rkdeveloptool wl 0 ./result/sd-image/*.img

What works?

Working:

• Ethernet
• WiFi
• HDMI
• GPU
• RTC
• USB 3.0
• USB 2.0

Not working:

• Bluetooth
• HDMI Audio
• LEDs
• Infrared Receive

Todo

• Document usage of rkdeveloptool to load SPL via maskrom, provide as flake input, etc.
• Create expect scripts for initial installation similar to visionfive-nix
• Document decompiled dts and other processes used to get to this point
• Make a pure GPT based image instead of using nixpkgs sdImage infrastructure, because rkdeveloptool ppt doesn't like this MBR hybrid stuff
  • Maybe use holey instead?
  • Figure out how to use systemd-repart as in ./repart.nix.unused
    • It seems that systemd-repart doesn't allow you to set the GPT table length, meaning partitions are limited to 2048 for the sector start size. But the rk3588 wants u-boot to be placed at sector 64.
