[bb]nfsブートできた！が・・・

nfsvers=3を指定することで、BeagleBoardからnfsブートすることができた。
よかったよかった。

あれ、止まってる・・・。

/lib/modules/2.6.32がない、というのが大きいようだ。
この環境は、元はといえばTI提供のもので、kernelは2.6.29-rc3-omap1だったのだ。
しかし、あまりにも動かなかったので、Androidで使っていた2.6.32を使っている。
その差が現れたか・・・。

対策は２つしかなく、

• kernelを2.6.29-rc3-omap1にする
• 環境を2.6.32にする

のどっちかだ。
あまり考えず、TIのAndroid kernelでmake modulesさせてみよう。
make modules_install・・・だけだと/lib以下にコピーされるので、INSTALL_MOD_PATHを指定してから実行。

やっぱり、無理矢理はだめなんかね・・・。
