未解決の問題にあげていますが、なぜかJFFS2で/dev/mtdblock2がmountできない問題があり、カーネルで大量のエラーが吐かれていることからカーネルの問題と仮定。
CONFIGの指定漏れがあるのかとも思いましたが、とりあえずwheezyで組み込まれていると思われる3.2.65のカーネルでそのままorion5x_defconfigを使って作成してみることにした。
セルフコンパイル
まずはセルフコンパイルで試す
# wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.2.65.tar.gz
# tar xvf linux-3.2.65.tar.gz
# cd linux-3.2.65
# vi Makefile
VERSION = 3
PATCHLEVEL = 2
SUBLEVEL = 65
EXTRAVERSION = -orion5x
EXTRAVERSIONに-orion5xを追記。これは後ほど実行するupdate-initramfsのために必要。
このままだとmachine IDが0x0000020eになり玄箱PROと識別されないのでパッチを当てる
# vi arch/arm/boot/Makefile
$(obj)/zImage: $(obj)/compressed/vmlinux FORCE
$(call if_changed,objcopy)
+ devio > foo 'wl 0xe3a01c05,4' 'wl 0xe38110e5,4'
+ cat foo $(obj)/zImage > zImage.new
+ mv zImage.new $(obj)/zImage
+ rm foo
@echo ' Kernel: $@ is ready'
コンパイル。作成するのはuImageではなくzImageとしておく。
# export ARCH=arm
# make orion5x_defconfig
# make menuconfig
変更箇所
- カーネルは圧縮率の高いLZMAに変更
- gzip圧縮のinitrdを使うので追加
- 起動時にdevtmpfsがあった方がよさそうなメッセージがあったので追加
- mtdblockのマウントができないので代替ツールとしてmtdram、mtdblockを追加(未解決の問題)
- sda2がext4なのでMから*に変更
- 他のサーバーの共有フォルダをマウントしたいのでCIFSを追加
- 言語はiso8859-1を基本に日本語とUTF-8を使えるように設定

ダメ。マウントできない。大量のエラーが出る症状も同じ。
なにがいけないのか分からない。
クロスコンパイル
何度も作り直すと玄箱PROでは時間がかかるのでクロスコンパイル環境を準備する。
VMware Player 7.1.0にdebian-7.8.0-i386-netinst.isoをセットしてDebian 7.xを導入。
Intel PC上のVMware Player環境でarmel向けのクロスコンパイル環境を作成する。
