前回でKernel 3.8.13ベースのソースコードと対応の取れた起動環境の構築ができた。
最近ではBBB用のもっと新しいKernelバージョンがリリースされているが、いたずらに最新版を追い求めてもハマるもとであるので とりあえずこのバージョンを開発ベースとし、必要に応じてKernelのバージョンアップを行う。
今回は各種環境情報を取得し、記録として残す事を目的とする。

rootfs”/”は/dev/mmcblk0p2となっている。
/dev/mmcblk0p2 on / type ext4 (rw,noatime,errors=remount-ro,data=ordered)
/dev/mmcblk0はmicro SDカードのraw deviceであり、/dev/mmcblk0p2はmicro SDカードの二番目のパーティション。
起動の途中までrootfs”/”はinitrdであり、その後/dev/mmcblk0p2に切り替えられる。
micro SDカードの一番目のパーティションは/dev/mmcblk0p1にmountされる。
/dev/mmcblk0p1 on /boot/uboot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
eMMC(/dev/mmcblk1)の二つのディレクトリは/media/bootおよび/media/rootfsにmountされる。
/dev/mmcblk1p2 on /media/rootfs type ext4 (rw,nosuid,nodev,relatime,data=ordered,uhelper=udisks) /dev/mmcblk1p1 on /media/boot type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1002,fmask=0022,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks)
eMMC内の情報を参照したいときにmicro SDカードを抜いて再起動させる必要がないので便利といえば便利であるが、間違って内容を壊す可能性も あるので慎重さが求められる。
各ファイルシステムの容量情報も見てみよう。

rootfsの空き容量が約1.8GBあるのでサーバーとしての実運用やログの内部保存を行わない限りは当分問題ない。
cpuinfoを見る。

Featuresに応じて最適なコンパイルオプションが変わるが課題とする。
Serialがオールゼロになっているが別に加工はしていない。
CPU Serialがオールゼロである分けが無いので取得していないのか取得できなかったのだろう。
引き続きプロセス情報を見てゆく。
