HOW-TO

This HOW-TO explains how to install linux on a Zire 72. Before go on you must backup your data. Running linux make your data to be lost.

The kernel used is 2.6.17

I use Debian Sarge 3.1, so this HOW-TO is specific for it.

Requirements

To compile Linux and cocoboot you need to install prc-tools and palmos sdk platform . In a Debian box you have to install the following packages with apt-get

prc-tools prc-tools-arm prc-tools-m68k prc-tools-utils pilrc pilot-link

The sdk platform can be obtained from: http://www.palmos.com/dev/tools/sdk/

To install it follow the instructions come with it.

Setup environment

To compile linux, cocoboot, etc. we must firs set the environmet to crosscompiling This can be made: 

   $ export CFLAGS="-mcpu=xscale -Wa,-mfpu=fpa11"
   $ export ARCH=arm
   $ export CROSS_COMPILE='arm-linux-'

Compiling cocoboot

Download cocoboot from svn repository 

   $ svn co https://svn.sourceforge.net/svnroot/hackndev/cocoboot/trunk cocoboot

Goto cocoboot dir 

   $ cd cocoboot

Build cocoboot 

   $ make

Now you should have a cocoboot.prc file 

   $ cd ..

Compiling kernel

Download linux kernel from svn repository 

$ svn co https://svn.sourceforge.net/svnroot/hackndev/linux4palm/linux/trunk linux

Goto linux directory 

$ cd linux

Execute the following commands 

$ make mrproper
$ make palmz72_defconfig
$ make zImage

Now kernel image is trunk/arch/arm/boot/zImage

Note: If an error ocurrs like asmloader.c:25:24: Standalone.h: No such file or directory, we can make a workaround. As root : 

$ cp /usr/share/prc-tools/include/Standalone.h /usr/local/share/palmdev/sdk-5r3/include/

Create initrd.gz

Installing

First backup your data. With pilot-link

Push sync button in your palm an then execute 

pilot-xfer -b backupdir  -p /dev/ttyUSB1

To install you must follow these steps.

1.- Edit linux.boot.cfg and leave it as: 

SWAP_DEV=$FILES_MNT/swap
ROOT_DEV=$FILES_MNT/gpe.ext

2.- Make swap file 

$ dd if=/dev/zero of=swap.fs bs=1k count=32k 
$ mkswap swap

3.- Mount your sd card in a directory. Example: /mnt/sdcard

4.- Copy swap, zImage, initrd.gz, gpe.ext, linux.boot.cfg to /mnt/sdcard

5.- Copy cocoboot.prc to /mnt/sdcard/palm/launcher

6.- Umount /mnt/sdcard

7.- Execute cocoboot in your palm
