BeagleBoneBlackをUbuntuで動かす

<http://tomowatanabe.hatenablog.com/entry/2013/12/15/202806>
ここを参考にして、
ubuntu-saucy-13.10-armhf-3.8.13-bone30.img.xz 
をSDに焼く。

i$ sudo dd bs=1m if=/Users/toshifumi/BeagleBoneBlack/ubuntu-saucy-13.10-armhf-3.8.13-bone30.img of=/dev/rdisk3

5分で焼けた。

BBBにいれてBootボタンを押しながら起動。

シリアルコンソールでログインOK。

etherもつながっています。

uEnv.txtを編集して再起動。Bootボタンを押さずにUbuntuが立ち上がりました。

mmcpart=2
bootfile=zImage  <---- 追加
optargs=fixrtc
uenvcmd=i2c mw 0x24 1 0x3e; kd=0; if test $mmcdev -eq 1; then mmc dev 0; if mmc
rescan; then kd=1; fi; mmc dev 1; fi; setenv mmcroot /dev/mmcblk${kd}p${mmcpart} ro
loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}
loadimage=load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${bootdir}/${bootfile}
mmcboot=echo Booting from mmc ...; run mmcargs; bootz ${kloadaddr} - ${fdtaddr}  <---- 追加

そして、2GBから4GBに拡張。
作業は参考ページと同じ。

$ df -h

今はまだサイズが1.8GBになってますので、fdiskで拡張します

ここまで来たら、先のBootボタンを押しながらリブートします

ubuntu@ubuntu-armhf:~$ sudo reboot

起動したら再びsshで接続してログイン後、resizeコマンドを叩きます

ubuntu@ubuntu-armhf:~$ sudo fdisk /dev/mmcblk0
