2025.01 現在、更新分でも同様の理由でビルドが通らなくなっています。

2022.11 現在、下記の手順ではリンク切れ等の理由でビルドが通らなくなっています。そのため https://github.com/mclewell/licheepi-nano-lcd をベースにして config や dts を調整したものを用意しました。

https://github.com/n24bass/licheepi-nano-lcd

まず、LicheePi Nano については @aselectoworksさんの記事が参考になります。

これらの記事では SD ブート用イメージの作成から USB デバイスの認識までの手順が記されていますが、残念ながら現時点では dl.sipeed.com など一部リンクが途切れています。USB/LCD/内蔵codeあります。LCD に対応したカーネルについては下記ページで公開されています。

https://github.com/MesihK/linux/tree/f1c100s-lcd

LCD は 480x272 や 800x480 のものが使用でき、私は 480x272 のものを用いています。dts や X での設定を合わせる必要があり、ビルドが面倒な方向けにはこちらにイメージファイルなどもあります。

https://steward-fu.github.io/website/mcu.htm#lichee-nano
https://steward-fu.github.io/website/mcu/f1c100s/flash_image.htm
リンク先がなくなっているので https://github.com/steward-fu/lichee-nano/releases/ を参照してください。
回路図など
ヘッドフォン出力などは dockを参照。ちょっと変則的な配線が必要です。

これに上記 MesihK さんのカーネルを組み合わせて内蔵 codec 対応を入れるのが良いと思います。

これらとは別に U-Boot、カーネル、ユーザランドをまとめて SD カードイメージを作成する buildroot を用意してみました。Mr-Bossmanさんのものに手を入れています。そちらでは U-Boot が LicheePi Nano に適合しないようなので、それだけを steward-fu さんのイメージから移せば動きます。他にちょっと余計なものが入っていたのを外したりしています。

https://github.com/n24bass/F1C100S-linux/tree/licheepi_nano_lcd480272

注意

mpg123 などで 44.1kHz サンプルの mp3 データを内蔵 code で再生するとピッチが速くなってしまうため、-r 48000 オプションを付加します。USB オーディオ IF を使う分には問題ありません。これは内蔵 codec のドライバが 44.1kHz に対応していないためです。PLL の設定にも手を入れる必要があるようです。
USB デバイスを適切に認識できない場合があります。セルフパワーか否かに依らず USB ハブを介すると更に調子が悪くなります。また、カーネルコンフィグによって使用できるデバイスは異なります。Trackpoint Keyboard とオーディオインターフェースは動きました。Ethernet や WiFi は未確認です。
UART コンソールから startx で X Window が立ち上がります。自動起動するには /etc/init.d/S99displaysetup に startx & を追加します。
X Window を使用しないなら /etc/init.d/S40xorg を外して /ete/inittab に getty /dev/tty0 のエントリを追加すれば LCD と USB キーボードのコンソールが使えます。
~~U-Boot を steward-fu さんのイメージから取り出して使うと LCD に起動ロゴとメッセージが出せます。~~
