Pyon's Diary

KURO-BOX/PRO (No.22) 外附 USB に書込みが出來た。

以前 2.5 吋の HDD を USB 經由で外付けした際、書込みが出來無かつた事が有つた。

• (No.08) HDD (外附、USB)を繋いでみた。
• (No.10) 外附 USB の HDD に書込め無かつた。

原因が良く判ら無つたので、其乃手の事に詳しい職場の同僚(し○めさん)に相談してみると「外附の筐體が惡いのでは？」と助言して呉れたので、彼の持つてゐる外附 USB の筐體(型番不明)を借りて來た。

結果として「出來た」。

• パーティション作成。
• EXT3 / XFS でパーティションを初期化。
• 母艦に繋ぎ變へて hddrootfs.tar.gz を複寫。
• KURO-BOX/PRO に繋ぎ變へて hddrootfs.tar.gz を解凍・展開。

全てすんなりと出來た。

と云ふ事は自分の所有している CENTURY CAC25U2 は理由は良く判ら無いけど KURO-BOX/PRO とは合性が惡いのか。

Flash 起動環境で外附 UDB HDD での開發環境を構築する。

一度 fdisk で舊いパーティションを全て削除する。

# fdisk /dev/sdb

The number of cylinders for this disk is set to 19077.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

/dev/sdb1 を EXT3 で、/dev/sdb[24] を XFS で初期化する。

/dev/sdb3 にスワップ領域を作成する。

# mkswap /dev/sdb3                                                            
Setting up swapspace version 1, size = 128970752 bytes

此處で一旦 KURO-BOX/PRO から外して母艦に繋ぎ變へ、

• ChangeMeDevHDD
• ChangeMyUbootEnv
• hddrootfs.tar.gz
• uImage.buffalo

を /dev/sdb4 に複寫して再度 KURO-BOX/PRO に接續する。

hddrootfs.tar.gz を解凍して /dev/sdb2 に展開する。

# mount /dev/sdb2 /mnt/usbdisk1/
XFS mounting filesystem sdb2
# mount /dev/sdb4 /mnt/usbdisk2/
XFS mounting filesystem sdb4
# cd /mnt/usbdisk1
# tar zxvf /mnt/usbdisk2/hddrootfs.tar.gz
./bin
./bin/bash
./bin/bash2
./bin/sh
(中略)
./var/lock/subsys
./var/proftpd
./var/www

最後に chroot をして gcc のバージョンが表示出來れば完了。

# chroot /mnt/usbdisk1


BusyBox v1.1.1 (2006.11.29-02:37+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.

gcc version 3.4.4 (release) (CodeSourcery ARM 2005q3-2)

此で外附 USB HDD で開發環境が動く事が確認出來た。

BRUSSELS (神樂坂)

ち○し○が宝塚へ觀劇に行つたので、夜一緒に神樂坂の BRUSSELS に行つた。行つたらカウンターが常連に占領されてゐた。

「蝦の夏野菜のフリット」を食べて歸つて來た。
