WG600HP & OpenWrt + mainline U-Boot (original) (raw)

なんとかここまで来た

WR8750N, WR9500Nも同様にサポート

動作OK

SPI (+SPI-NOR)
GPIO
LED
- 5カ所全10個全てath9kチップ (AR938x) に接続されている為、利用可能になるのは無線のprobeが走ってから
Ethernet
WLAN (SoC/PCIe)
- 認識のみ確認
USB
- ただし内部ハブのRESETがath9kチップ (AR938x) に接続されている関係上、ハブの認識されるタイミングが無線チップのprobe後になる

動作NG

~~WLAN (SoC)~~
- ~~現状何故か機能せずブートが止まる~~
  * RESETのdeassertが足りていなかったのが原因。QCA955xではath9kドライバによりハンドルされるが、AR934xでは実装が欠落

備考

U-BootはNetBSD系Atermの 0x20000 (128KiB) しか無いブートローダ領域に収める為、ネットワークからSPIサポートまでや、コマンド類を最低限のもの以外全て切って徹底的にサイズを落とした。
- 削る作業が滅茶苦茶キツかった
- ブートは実質 bootm のみ、復旧の為にイメージを投入する手段は loadb, loadx, loady のみ
- SPI-NOR内がメモリマップされるので、ファームウェア領域の始点に直接bootmする
- LZMAやGZIPのdecompressionサポートも切った為、LZMA圧縮済kernelの展開はlzma-loaderで実施してU-Bootには未圧縮として渡す
  * lzma-loaderのボードサポート部分では、U-Bootでサイズの関係上入れられていないネットワーク周りなどの構成を行う

bootlog

LuCIを日本語訳無し最低限、USBストレージドライバとvfatドライバを組み込んだビルド
