Q19: I am using a C3x00, and I want to use kernel 2.6.23.1 yonggun with uboot. How can I install Debian EABI on SD?

A19: The installation comes in five parts:

• Prepare the SD;
• Install the EABI rootfs;
• Install uboot;
• Flash the kernel
• System configurations

PREPARATION

1. Prepare the SD card

[Note: If you are already using the new pdaXrom versions using uboot, you can simply repartition and reformat the internal drive, without using the method below. Go directly to II)]

2. Boot into Linux Emergency Mode

a. Remove power sources,

b. Press B and D while putting back the battery & lock the cover switch & power on.

c. In the command prompt, login as root.

3. Repartition the internal drive using fdisk /dev/mmcblk0 ( http://www.oesf.org/index.php?title=Multiple_partitions_on_a_CF_/_SD_card ). Create two partitions. /dev/mmcblk0p1 is the root partition (ext3); /dev/mmcblk0p2 is the swap partition (default ~180.9MB in Debian CD installation, but you can make a bigger swap partition if you want to run very resource-hungry programs, or do onboard compilation).

4. Reformat the two partitions:

   mke2fs -j /dev/mmcblk0p1
   mkswap /dev/mmcblk0p2

SYSTEM INSTALLATION

5. Install the system, kernel modules and after installation files

5.1 Extract the system rootfs tarball, kernel modules and after installation files to the SD card

   mount /dev/mmcblk0p1 /mnt/card 

Plug in the CF card with armel-root-fs.tar (first uncompress the .bz2 format), modules-2.6.23.1-yonggun.tar.gz, and zaurus-debian-eabi-afterinstall_1.1.tar.gz

   cd /mnt/cf 
   cp armel-root-fs.tar modules-2.6.23.1-yonggun.tar.gz zaurus-debian-eabi-afterinstall_1.1.tar.gz /mnt/card
   cd /mnt/card
   tar -xvpf armel-root-fs.tar 
   cd armel-root-fs
   mv ./* ../
   cd .. 
   tar -xvpzf modules-2.6.23.1-yonggun.tar.gz
   tar -xvzf zaurus-debian-eabi-afterinstall_1.1.tar.gz
   rm -r armel-root-fs armel-root-fs.tar modules-2.6.23.1-yonggun.tar.gz zaurus-debian-eabi-afterinstall_1.1.tar.gz

5.2 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)

   cd /media/card/etc 
   nano fstab 

Make sure /dev/mmcblk0p1 mount to / and make it bootable. (Also disable the /dev/hdaX entries because you don't have a microdrive)

UBOOT INSTALLATION

6. Install uboot (adapted from http://www.pdaxrom.org/?q=node/106 )

If your Zaurus is already using uboot, go directly to 7.

Fresh installation on Zaurus with Sharp bootloader (applicable to Sharp rom, Cacko rom, pdaXrom 1.1.0 Beta 1/Beta3, pdaXii, Angstrom)

a. Download and unzip the u-boot archive to CF, you will see FOUR files: emergenc.img, u-boot.bin, updater.pro and updater.sh

b. Remove baterry, wait 5 secs, place battery and attach AC power.

c. Press "OK" key and keep it pressed, then press "On/Off" button.

d. In the maintenance menu, choose "4" (Update) in the first screen, "1" (CF) in the second and "Y" in the third

e. The kernel will be flashed

f. Press and hold [OK] during reboot - emergency system will boot up

KERNEL INSTALLATION

7. Flash the kernel in the uboot emergency system

7.1 Eject the CF card and remove all the uboot installation files on the CF card.

7.2 Download and copy kernel.img-2.6.23.1-yonggun-eabi-cpufreq-hda1 (rename to kernel.img) and autoboot.sh (simply remove the tar.gz extension; it is just a plain text file) and put them on the CF card.

7.3 Reboot the Zaurus while pressing the [Ok] button.

7.4 In the uboot emergency system, you will be asked "Proceed with debian installation or boot to emergency system? [y/n]". Press [y] and [Enter]. The new kernel flashing process will start and complete very quickly.

After reboot, your Z will be running Debian EABI!

[NOTE: Press [1] when (re)booting]

FIRST BOOT & SYSTEM CONFIGURATIONS

Note: The first booting may fail and complain about being "unable to open an initial console". If that is the case, boot into the Linux Emergency mode and do this:

   mount /dev/hda1 /mnt/cf
   cd /mnt/cf/dev
   MAKEDEV console

After that, reboot again. (Press [1] when boot starts)

8. First login

   Login: root
   Root password : (no password)

9. Set up date and time

   date MMDDHHMMYYYY   ##Example: 102906572007

10. The first part of after installation configurations The after installation process is divided into two parts. Now let's do the first part.

[Note: The after installation scripts (1st-cfg.sh and 2nd-cfg.sh) are intended to be applied only once to a clean, fresh install before any tweaking. Mixing any other different tweak with the application of these scripts may produce unexpected results.] Do this and follow the instructions:

   cd ../afterinstall    ## Use the [Tab] key to help you get  "/"
   ../afterinstall/1st-cfg.sh

When the process completes, you will be reminded to set up a proper network connection before proceeding to the second part.

11. Set up network connection

11.1 Edit the network connection profile

   nano /etc/network/interfaces. 

For example, for my Symbol Spectrum 24 wifi CF with a static IP in a home network:

   auto lo
   iface lo inet loopback
   auto eth2
   # iface eth2 inet dhcp
   allow-hotplug eth2
   iface eth2 inet static
   address 192.168.0.199
   network 192.168.0.0
   netmask 255.255.255.0
   broadcast 192.168.0.255
   gateway 192.168.0.1
   wireless-essid DON'T_BE_STUPID
   wireless-key I_KNOW_YOU_KNOW_THAT
   wireless-mode managed
   dns-nameservers 192.168.0.1

11.2 Edit gateway

   nano /etc/resolv.conf

Simply put down your router's IP, e.g.

   192.168.0.1

11.3 Reload the network profile

   /etc/init.d/networking restart

11.4 Plug in your wifi CF card if it isn't in the slot yet.

11.5 You can do a very simple test to see if your network connection is working: For example, if your Zaurus is connecting to a wireless router, then do

   ping 192.168.0.1    ##Or the correct IP address of the router
   ping www.google.com    ##This will make sure that your Zaurus can connect to the internet

If ping doesn't report any package loss, then you are ready to proceed to 12.

12. Now we begin the second part of the after installation process. Go to the afterinstallation directory again. Then

   ./2nd-cfg.sh

When asked to confirm whether you want to install anything, just type [y] and [Enter]. After this, a fully working EABI system is set up. Time to play!

That's it. Have fun!

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 Uboot Emergency Mode again.

Back to the main list.
