NetBSD RPiはじめました

ここがめっちゃ参考になった: NetBSD/evbarm 6.1 on Raspberry Pi

SDカードの一発目を作るのにまずさいしょに Raspbian のイメージを持って来てSDカードにddで書き込み。

progress -f 2013-09-25-wheezy-raspbian.img dd of=/dev/rsd0d bs=1m

するとDOSパーティションに必要なファイルが入った状態のSDカードが 出来上がるので、あとはfdiskでパーティション1をNetBSD(169)に変えて、 SDカードの末端までサイズを拡げるだけでよいので楽ちん。

DOSパーティションの kernel.img をNetBSDカーネルに置き換えて cmdline.txt も修正してブート。
