玄箱 PRO #2
multi-user modeで起動するまでを、備忘録としてまとめる。全面的に書き直し。
host(192.168.0.19)での作業
- hostマシンに、FreeBSD 8.0-CURRENTを用意する。
- hostマシンがNFSで公開したディレクトリを、armマシン（玄箱 PRO）がrootディレクトリとしてマウントしたいのだが、現状の8.0-CURRENTのNFSで公開したディレクトリはうまくマウントできないようなので、コンパイルする8.0-CURRENTとNFSサーバーは別にした。めんどくさいのでhostマシンとする。
- hostマシンでFreeBSD/armのコンパイル
% su - # cd /usr/src # setenv DESTDIR /nfsroot/arm-8-le # mkdir -p $DESTDIR # make -j 4 buildworld TARGET_ARCH=arm # make installworld TARGET_ARCH=arm # make distrib-dirs TARGET_ARCH=arm # make distribution TARGET_ARCH=arm
- kernelを作る
# make buildkernel TARGET_ARCH=arm KERNCONF=DB-88F5XXX
- kernel.binを、hostの/tftproot/mv5281/にコピー
# cp /usr/obj/arm/usr/src/sys/DB-88F5XXX/kernel.bin /tftproot/mv5281/
- hostマシンのtftp、dhcpを設定する
玄箱PROを起動してsingle-user modeで起動するか確認
玄箱PROを起動して、U-Bootのプロンプトに落とす。

とすると、FreeBSDが起動する。問題がなければsingle-user modeに落ちるはず。
玄箱 PROのmulti-user modeでの起動
最低限の/etc/rc.conf (/nfsroot/arm-8-le/etc/rc.conf)と/etc/fstab (/nfsroot/arm-8-le/etc/fstab)の設定を書く。あと、/etc/ttysも適切に直す必要がある。
/etc/rc.conf
sshd_enable="YES" rpcbind_enable="YES" nfs_client_enable="YES" rpc_lockd_enable="YES" rpc_statd_enable="YES"
/etc/fstab
192.168.0.19:/nfsroot/arm-8-le / nfs rw 0 0
上記の手順で起動して、single-user modeからexitで抜ければmulti-user modeでの処理が始まる。
（現在の8.0-CURRENTは、lock order reversal:と、いろいろうるさいログを出すので省略）

時刻が合ってないので、あわせる必要がある。ハードディスクが見えてないのが、少し悲しい。
