LTSI Kernel Porting Information: Debian Wheezy

=LTSI Kernel Porting Information: Debian GNU/Linux 7.0 (Wheezy), Jessie(Debian next version's codename) and Sid =

The following shows the information of the result of porting LTSI Kernel to Debian GNU/Linux 7.0 (Wheezy), Jessie (Debian next version's codename) and sid. Anyone is more than well come to add information here in the following format

=What had been done:= (Please describe your changes for LTSI to work for the target distribution)

Updated linux kernel
I supported CuBox to LTSI 3.4.46. This kernel does not support CuBox, I needed to backports patches from latest kernel. I supported SATA, USB, Ether, serial and SPI. SDHI does not support. If we boot using this kenrel, we need to use Ether or USB.

Checked arm architecture in Debian
Debian is preparing armel and armhf as the 32bit arm architecture. I checked operation in both.

=Changes:= (Please describe summary of your changes and suggestions for others)

Change etc/inittab
I added a line to etc/inittab following: T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100

Usually, serial console is not enabled Debian. First, because we need to login CuBox from serial console, you need to add this line.

Add etc/fstab
When Debian does not use an installer, etc/fstab is usually empty. Therefore, a user needs to change. I added the device used as rootfs after boot to etc/fstab following: proc           /proc   proc    defaults                        0       0 /dev/sda1      /       ext2    defaults,errors=remount-ro      0       1

=Patches:= (link to your patches for LTSI if you have any)

Linux kernel
I am managing patches in https://github.com/iwamatsu/linux/tree/3.4.46-ltsi-cubox Most patches were cherry-picked from linux upstream kernel.

= Notes:=

How to boot from USB (This is really my note...):
CuBox>> usb start ; ext2load usb 0 2000000 uImage ; bootm 2000000
