Aramdillo-840で起動時間を短縮するためにユーザーランドをsquashfsにしてみました。 起動時にエラーが発生する等の問題が残っていますが、現時点の内容を本ブログで紹介します。
Armadillo-840の標準のユーザーランドでは起動時間が約30秒程度かかります。 そのうちNORフラッシュからRAMに展開するための時間がかなりを占めています。 そのため、ここではNORフラッシュに書き込まれたsquashfsをそのままmountするよう変更してみます。
1. ユーザーランドイメージの作成と書込み
Atmark Distで一度イメージを作成した後に、以下のコマンドを実行してromfs/etc/fstabを開いてください。
[atde ~/atmark-dist]$ editor romfs/etc/fstab
romfs/etc/fstabを以下のように修正してください。
/dev/mtdblock5 / squashfs defaults 0 1 proc /proc proc defaults 0 0 usbfs /proc/bus/usb usbfs defaults 0 0 sysfs /sys sysfs defaults 0 0 udev /dev tmpfs mode=0755 0 0 /dev/flashblk/firmware /opt/firmware squashfs defaults 0 0 /dev/flashblk/license /opt/license squashfs defaults 0 0
※: 修正は一行目のみです。
上記修正後に、以下のコマンドを実行してユーザーランドイメージを作成してください。
[atde ~/atmark-dist]$ cd romfs [atde ~/atmark-dist/romfs]$ mksquashfs ./ ../userland.img
上記で作成したuserland.imgを通常のユーザーランドイメージの書き込みと同じ手順でArmadilloのユーザーランドパーティションに書き込んでください。
2. 起動パラメータの設定
保守モードで起動し、以下のコマンドを実行し、起動パラメータの設定とLinuxの起動を行ってください。
hermit> setenv console=ttySC2,115200 noinitrd rootwait root=/dev/mtdblock5 hermit> boot
3. 起動ログ
起動するとログが以下のように表示され、ログインプロンプトが表示されます。
