電源の USB-C の上にある BOOT ボタンを押しながら、USB-C を PC の USB-C に接続すれば T-HEAD USB download gadget として認識されるはずです。
自分は PC に Ubuntu/ThinkPad を使っているので dmesglsusb は次のようになります。
$ sudo dmesg | tail -5

Windows の方は先程のダウンロード先にドライバーと fastboot バイナリーがあります。
認識できたらアーカイブ内の burn_gnome_gpu.sh を実行すれば OK です。イメージ同梱の fastboot コマンドは Linux バイナリで、burn_gnome_gpu.sh もシェルスクリプトなので、Windows の方も WSL2 の Ubuntu でやったほうが簡単かもしれません。ドライバーも入れる必要がありません（認識のさせ方を記事の最後の「関連」に記載しておきます）

起動
イメージが焼けたら HDMI をしっかり接続して USB-C 電源に接続すれば、ファンが始動し始め GUI が表示されると思います。ちなみにうちの 2560 x 1440 HDMI モニターだとログイン GDM から 2560 x 480 みたいな解像度で起動しました。ｗ

あとこれは趣味ですが、デフォルトエディタを vim にしています。
$ sudo update-alternatives --config editor
There are 3 choices for the alternative editor (providing /usr/bin/editor).
Selection Path Priority Status

1 /bin/nano 40 manual mode
* 2 /usr/bin/vim.basic 30 manual mode
3 /usr/bin/vim.tiny 15 manual mode
Press <enter> to keep the current choice[*], or type selection number:

起動ですが（予想はしていましたが）恐らく GPU ドライバーが未完成のため（GPU のせいでなくてフォントが描けてなさそう）真っ黒画面でした。コマンドを打つとカーソルは動いているのが見えるので動作はしていそうです。（スクリーンショット右下で CPU が MAX になっているのは偶然です）
