Q16: I am using a Cxx0 or C1000. How can I install Debian EABI to my SD card?

A16: The installation comes in three parts.

• Install the Angstrom kernel & Angstrom system
• Install the Debian EABI system
• After installation configurations

Note:

• If your Zaurus is already running with uboot (such as the new pdaXrom versions), then you have to do a NAND Restore to revert to the factory stock rom in order to flash this kernel.
• If you want to keep using uboot, go to Q20 now.
• The 2.6.22 and 2.6.23 kernels (2.6.23 verified with angstrom 20071104) have troubles with altboot, so don't use it for now unless you know how to solve the problems.

1. INSTALL THE ANGSTROM KERNEL & ANGSTROM SYSTEM Install the Angstrom 2.6.21 kernel & system in NAND flash area.

Please follow the instructions here: http://www.angstrom-distribution.org/c1000-install-instructions resp. here: http://www.angstrom-distribution.org/zaurus-c7x0-c8x0 to install the latest angstrom.

You'll have to replace the kernel and modules with 2.6.21 ones. Angstrom itself doesn't offer them any more. You can find copies here: http://www.oesf.org/forum/index.php?showtopic=24960&st=210&start=210

2. INSTALL THE DEBIAN EABI SYSTEM

2. Install the Debian system

2.1 Repartition and reformat the SD :

Create a linux (preferably Ext3) partition on the SD (for details see: http://www.oesf.org/index.php?title=Multiple_partitions_on_a_CF_/_SD_card )

2.2 Format the partition:

   mkfs.ext3 /dev/mmcblk0p1

2.3 Install the rootfs

a. Get the rootfs tarball

b. Uncompress it to the root of the SD:

   tar -xvjpf hddrootfs.tar.gz

2.4 Put the 2.6.21 kernel modules on the SD

   cp -a /lib/modules  /media/card/lib/modules

2.5 Modify some system setting files in the Debian system

The debian boot process looks for init.sysvinit instead of init, so :

   cd /media/card/sbin 
   ln -s init init.sysvinit

You need to change the mounted root from the standard /dev/hda1 (Microdrive) for titchy to /dev/mmcblk0p1 (= SD card)

Edit /etc/fstab to make /dev/mmcblk0p1 mount to / and make it bootable. (Remember to remove the lines mounting /dev/hdaX to / because you don't have a microdrive)

2.6 Still in Angstrom : Connect to the net, run

   ipkg update && ipkg install altboot

[Notes : You'll have to edit network settings before you can reach your network (/etc/network/interfaces; /etc/resolv.conf contains some kuro-specific-things)]

FIRST BOOT & AFTER INSTALLATION CONFIGURATIONS

3. Reboot

Reboot and hit the "any" key when asked to launch altboot then choose "boot from SD" (the "any" key is the 35th key counting diagonal from the lower left corner or maybe some other key)

At this stage, booting may fail and complain about being "unable to open an initial console".

If that is the case, do this:

   cd ../dev    ## use the [Tab] key to help you find "/"
   MAKEDEV console

After that, reboot again.

4. First login

   Login: root
   Root password : (no password)

5. Set up date and time

   date MMDDHHMMYYYY   ##Example: 102906572007

6. After installation configurations

Please see this thread: http://www.oesf.org/forum/index.php?showtopic=24941

And perhaps you may also be interested to check out this after installation tarball and script, which may save you some time extracting stuff from the Angstrom and pdaXrom packages.

CHANGE KERNELS

If you want to switch to other kernels,

a. First extract and copy the corresponding kernel modules to /lib/modules

b. Prepare the correct kernel image (zImage.bin) and updater.sh and install them in the Flash Menu again.

Back to the main list.
