- ログを大量かつ長期間とっておきたいので念のためディスク容量を増やしておきたい
- 開発者向けガイドを読むとMMCスロットがあり、まさにうってつけである
MMCはシステム運用に十分な信頼性を確保できない為、ファイル交換やログ保存用等にご利用ください。
- たまたま余っていたSDカードをもらったので挿してみる
- ここに挿す
- mmcblk1というデバイス名で認識された

- 今回はNTFSでフォーマットしてみる
root@obsiot:/dev# mkfs -t ntfs /dev/mmcblk1p1 Cluster size has been automatically set to 4096 bytes. Initializing device with zeroes: 0% 100% - Done. : 2時間余りかかった Creating NTFS volume structures. mkntfs completed successfully. Have a nice day.
他で /var/tmp/storage を使っているのを見たので、そこにマウントしようとしたらハマる
mountしてファイルの読み書きができることを確認/etc/fstabを修正して再起動
root@obsiot:# vi /etc/fstab /dev/mmcblk1p1 /var/tmp/storage ntfs defaults 0 0 :末尾に追記
- しかし、STATUSのLEDが緑点滅になっている
SIM が無い状態での正常稼働または電波受信待機状態への移行待ち状態。

- 関係あるのかわからんが、
/var/配下でエラーになっているようなので、マウントポイントを/media/storageに変えてみる
root@obsiot:# vi /etc/fstab /dev/mmcblk1p1 /media/storage ntfs defaults 0 0 :マウントポイントを変更
- STATUSのLEDは白点滅（モバイル回線電波：強）、SSIDも検出された
- マウントもちゃんとされた

- 後で
/var/配下で他のパスもいくつか試したがやっぱり同じエラーになった
