| # Description | ||
|
|
||
| This document on how I configure [NixOS](https://nixos.org/) on [NanoPC-T4](https://wiki.friendlyarm.com/wiki/index.php/NanoPC-T4). | ||
|
|
||
| # Installation | ||
|
|
||
| To install NixOS on you can follow the [official instructions](https://nixos.wiki/wiki/NixOS_on_ARM/NanoPC-T4) and use the [pre-built images](https://github.com/tmountain/arch-nanopct4/tree/main/images/) from @tmountain. You can also build the U-Boot image yourself from `nixpkgs` based on changes added in [#111034](https://github.com/NixOS/nixpkgs/pull/111034). | ||
|
|
||
| ## NixOS on NVMe with ZFS | ||
|
|
||
| It is possible to migrate the OS from the eMMC storage to the NVMe. | ||
|
|
||
| In my case I migrated `/`, `/nix`, and `/home`, leaving `/boot` on the eMMC. | ||
|
|
||
| Create the ZFS pool and three filesystems on the SSD: | ||
| ```sh | ||
| zpool create -O xattr=sa -O acltype=posixacl -O mountpoint=none rpool /dev/nvme0n1 | ||
| for VOL in nix root home; do | ||
| zfs create -o mountpoint=legacy rpool/$VOL | ||
| mkdir /mnt/$VOL | ||
| mount.zfs rpool/$VOL /mnt/$VOL | ||
| done | ||
| ``` | ||
| Then sync the original filesystem on eMMC to the new volumes: | ||
| ```sh | ||
| rsync -rax /. /mnt/root | ||
| rsync -rax /nix/. /mnt/nix | ||
| rsync -rax /home/. /mnt/home | ||
| rsync -rax /boot/. / | ||
| ``` | ||
| Afterwards create a configuration that looks like this: | ||
| ```nix | ||
| { | ||
| # TODO: Make sure to update the eMMC device UUID! | ||
| fileSystems."/boot" = { device = "/dev/disk/by-uuid/1234-5678"; fsType = "ext4"; }; | ||
| fileSystems."/" = { device = "rpool/root"; fsType = "zfs"; }; | ||
| fileSystems."/nix" = { device = "rpool/nix"; fsType = "zfs"; }; | ||
| fileSystems."/home" = { device = "rpool/home"; fsType = "zfs"; }; | ||
| } | ||
| ``` | ||
| And rebuild he system: | ||
| ```sh | ||
| sudo nixos-rebuild boot | ||
| ``` | ||
| :warning: __IMPORTANT:__ After that it's necessary to run all the four `rsync` commands again to sync filesystems. | ||
|
|
||
| Once everything is synced you can finally reboot. | ||
|
|
||
| You should also clean up `/boot` afterwards. | ||
|
|
||
| # UART Debug Console | ||
|
|
||
| Device provides a Debug UART 4 Pin 2.54mm header connection, 3V level, 1500000bps. | ||
|
|
||
| To connect to you will need a USB to UART converter/receiver that supports the speed of 1500000bps. | ||
|
|
||
| The serial port parameters are [8-N-1](https://en.wikipedia.org/wiki/8-N-1). | ||
|
|
||
| A reader using `CP2102` chip did not work but `FT232RL` works fine: | ||
|
|
||
|  | ||
|
|
||
| You can use `minicom` or `picocom` to connect: | ||
| ``` | ||
| sudo minicom -b 1500000 -D /dev/ttyUSB0 | ||
| sudo picocom -b 1500000 /dev/ttyUSB0 | ||
| ``` | ||
| But you'll need to disable flow control with `Ctrl-A x`. | ||
|
|
||
| Here is a good overview of UART USB-to-Serial adapters: | ||

| Pin layout where #4 is next to USB-C port: | ||
|
|
||
| | Pin num.| #1 | #2 | #3 | #4 | | ||
| |---------|-----|----|----|----| | ||
| | Purpose | GND | V5 | TX | RX | | ||
|
|
||
| Remember that the `TX` and `RX` ports should be swapped between UART adapter and the board. | ||
|
|
||
| The V5 pin does not need to be connected if you're powering the board from another source. | ||
|
|
||
| See the full board diagram for more details: | ||
|
|
||
|  | ||
|
|
||
| You can access the recovery console by holding the __Recovery__ button and then pressing the __Power__ button. | ||
| For this to work the device will have to be off, which requires holding the __Power__ button long enough. | ||
