ZedBoard向けYoctoのビルド (3)

ZedBoardにダウンロードするために、SDカードのイメージを作成する。 まずはSDカードを用意するところからだ。僕の場合はUbuntu LinuxVirtualBox上で動かしているので、VirtualBox上でSDカードを認識させるところから初める。 dmesgをすると/dev/sdbに認識されているようだった。

で、fdiskを使ってパーティションを作成して、成功のメッセージは出るのだが、何故だかうまくパーティションが作成できていないようだった (lsblkで確認してもsdb1とsdb2が作成されていない)。 変だなと思って、一度SDカードをWindowsでフォーマットしようとしたが、Windows上でフォーマットに失敗する。これはSDカードが壊れたかな? と思って、別のBUFFALOのツールを使ってフォーマットするとうまくいった。何だったんだ。。。

$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0   100G  0 disk
├─sda1   8:1    0    96G  0 part /
├─sda2   8:2    0     1K  0 part
└─sda5   8:5    0     4G  0 part [SWAP]
sdb      8:16   1    15G  0 disk
├─sdb1   8:17   1   500M  0 part /media/masayuki/ZED_BOOT
└─sdb2   8:18   1  14.5G  0 part /media/masayuki/ROOT_FS
sr0     11:0    1  1024M  0 rom

再度fdiskにかけてFATパーティション(ブート用)とEXT3パーティション(ファイルシステム用)を作成する。 これで書き込み用のパーティションが作成された。

それぞれに書き込み用のファイルシステムとマウントポイントを作成する。 (下記のコマンドについて、FPGAマガジンの記事は誤植があった。ROOT_FSをsdb1に作成するようになっていた)。

sudo mkfs.msdos -n ZED_BOOT /dev/sdb1
sudo mkfs.ext4 -L ROOT_FS /dev/sdb2
sudo mount /dev/sdb1 /mnt/ZED_BOOT
sudo mount /dev/sdb2 /mnt/ROOT_FS

そして必要なファイルをどんどんコピーしていき、最後にumountしてSDディスクの作成完了。

sudo umount /mnt/ZED_BOOT /mnt/ROOT_FS
$ sudo -i
# sudo mount /dev/sdb2 /mnt/ROOT_FS/; sudo mount /dev/sdb1 /mnt/ZED_BOOT/
# cd /mnt/ZED_BOOT/
# ls -1

$ sudo umount /mnt/ZED_BOOT /mnt/ROOT_FS

これをZedBoadに差して、TeraTermからシリアルコンソールを使ってブートの様子を見た。

今回は自分でブートさせなければいけないらしい。

これ、どうやって解決すればいいんだろう。。。とりあえず今日はここまで。
