作業中のファイルやらはこのへんNetBSD/netwalkerに。

しょーもないバグがあって途中で止まっていたのだが、見つけて修正したら mountroot まで来た。
まだ割込みとかぜんぜんなのでtzicとかepitとかはダミーですが、そんなことよりシリアル入力ができませんよ？(ポーリングでも)

もしかしてそもそも基板のシリアル線のRXDの位置を間違えているのだろうか。
それとも抵抗か何か必要なのか。謎だ。一度Linuxで確認したほうがいいかも。

CortexA8 の cpu cache size が変だったのも修正したので、cpu0: 〜 の所が綺麗になった。 ※currentでも同じように既に修正された。L2キャッシュのサイズが間違ってるけど :P

今日のdmesg
