延々やってるが割り込みが入らない。うーん。
@h_kenken氏によると kernel を 0x90000000 + 512Mb - 1Mb? (一部のファイルしか貰ってないので詳細不明…) にコピーしなおして pmap すると動くそうだが、何故そうなるか謎。 手元では確認できず。ARMv7のsecure/unsecure関係かなと思ってpdfを読むが、よくわからん…。かなり飽きてきた :P

ふと思って boot.conf から quiet を外して debug 付けて SD recovery disk の linux を boot させてみた。メモ代わりに貼っておく。 メモリが512MBじゃなくて480MBとか、いろいろ謎な所があるなぁ。Linuxはそういうものなのかもしれん。 このままハマり続けるようであればLinuxのbuild環境作ってlinux kernelでいろいろテストしたほうがいいかも。
