$ sudo add-apt-repository ppa:linaro-maintainers/tools $ sudo apt-get update $ sudo apt-get install linaro-image-tools # t-flash를 넣고 sudo fdisk -l 을 통해 '/dev/sdX' node를 확인한다.
저의 환경은 /dev/sde입니다.
Building a Custom Image 방법대로 f-flash에 복구합니다.

ODROID-PC는 LCD가 없고 HDMI만 있습니다.
따라서 HDMI 출력이 되도록 kernel에 작업해야 합니다.
Linaro에서 Origen 보드에 HDMI 출력이 가능하도록 작업을 하였습니다.
Origen의 kernel을 ODROID-PC의 H/W에 맞게 수정해 줘야 합니다.
tobetter님이 이 작업을 해주셨고 github에 올려 해 주셨습니다.

make -j6 후 만들어진 zImage를 fastboot를 이용하여 write합니다.
복구가 끝나면 /dev/sde2를 mount하여 rootfs를 pc로 복사 시킵니다.

Linaro Ubuntu의 rootfs가 매우 크기 때문에 ODROID-PC의 partition table을 다시 만들어야 합니다.

두 partition을 format합니다.
[~/projects/linaro_ubuntu]$ sudo mount /dev/sde2 /media/microSD/

복사해 놓은 rootfs를 t-flash에 복사합니다.
uboot에서 bootargs와 bootcmd를 아래와 같이 수정 합니다.

그리고 rootfs에 /etc/X11/xorg.conf를 아래와 같이 추가하여 주시면 됩니다.

추가로 SATA로 HDD에 rootfs를 넣어서 부팅해 보았습니다.
HDD의 첫번째 파티션을 ext4로 format하고 rootfs를 넣습니다.
github에 올라가 있는 커널에 SATA가 동작하도록 올렸습니다.
uboot에서 bootargs를 아래와 같이 /dev/sda1로 수정 합니다.
그리고 SATA Driver가 동작하기 위한 시간을 주기 위해 rootdelay=10 로 수정합니다.
setenv bootargs 'root=/dev/sda1 rw rootfstype=ext4 init=/sbin/init console=ttySAC1,115200 rootdelay=10'
