Howto setup ipv6 on the Sharp Zaurus.
From: http://www.kame.net/newsletter/20020425/howto.txt
It's my pleasure to help you. You would need the Linux kernel source for
the Sharp Zaurus and the cross-compiling environment bothavailable at Sharp's
web site (http://more.sbc.co.jp/slj/index.asp). There also is a good documentation
to build the kernel (http://more.sbc.co.jp/slj/source/build_image112.asp).
The cross-compiling environment can be built on RedHat Linux. You will
need a CompactFlash memory card (>32MB) to update the kernel.
The procedure is as follows:
1. Update your FlashROM image (binary) to 1.12 or 1.13
2. Prepare the cross-compiling environment.
3. Get the kernel source.
4. Configure and build the kernel.
5. Transfer the kernel image to FlashROM.
6. Enable the IPv6 code
Please note that the newly built kernel does NOT support SD cards as described
in the Sharp's document.
The following is the detailed procedures:
1. Update your FlashROM image (binary) to 1.12 or 1.13
The latest FlashROM image and the kernel source code is different from the
shipped FlashROM image. I recommend that you first update the binary FlashROM
image to the latest version which matches the version of the kernel you are
going to build. The FlashROM image can be downloaded from http://more.sbc.co.jp/slj/download.asp
The update procedure is documented in http://more.sbc.co.jp/slj/download/readme/readme_romimage112.asp
Please read it carefully. If you use the Windows driver (Intellisync or Qtopia
Desktop), you will also need to update these drivers.
2. Prepare the cross-compiling environment.
See Cross-compiling howto
3. Get the kernel source.
You can either download the entire source
http://more.sbc.co.jp/slj/source/linux-sl5000d-20020318.tar.bz2
or the patch to ARM-Linux kernel
http://more.sbc.co.jp/slj/source/linux-2.4.6-rmk1-np2-embedix-20011228-sl5000d-20020318.gz
As describe in the Sharp's document, you will also need
linux-2.4.6.tar.bz2
patch-2.4.6-rmk1.gz
diff-2.4.6-rmk1-np2.gz
if you are going to use the patch.
4. Configure and build the kernel.
As the document says, please configure the kernel as follows:
$ cd linux
$ make menuconfig
--> Load an Alternate Configuration File
input "arch/arm/def-configs/collie"
select "ok"
select "Exit"
Do you wish to save your kernel configuration? ->
Yes
The default configuration does not enable IPv6, so you will also need
to enable it.
$ make menuconfig
--> Networking options
--> The IPv6 protocol (EXPERIMENTAL)
You can either embed the IPv6 protocol stack to the kernel (displayed
as '<*>') or make it separated as a loadable module (displayed as
'<M>'). I tried the latter.
Now, you can build the kernel.
$ make dep; make clean; make zImage
I you are going to build the IPv6 code as a module, please do
$ make modules
also.
5. Transfer the kernel image to FlashROM.
Copy the built kernel (linux/arm/boot/zImage) to an empty CompactFlash card.
The update procedure is same as the binary update procedure except that you
use the 'zImage' file instead of 'ROMIMAGE' file. Please refer http://more.sbc.co.jp/slj/download/readme/readme_romimage112.asp
6. Enable the IPv6 code
If you have embedded the IPv6 protocol stack to the kernel, you are ready.
You can see 'inet6 addr' lines with ifconfig command.
If you have built as a module, you should copy the module and load it. Copy
the linux/net/ipv6/ipv6.o to CompactFlash card, and copy it to
the Zaurus's built-in ROM.
# mkdir -p /lib/modules/2.4.6-rmk1-np2-embedix/kernel/net/ipv6/
# cp /mnt/cf/ipv6.o /lib/modules/2.4.6-rmk1-np2-embedix/kernel/net/ipv6/
# depmod -a
# modprobe ipv6
Please ask me if you encounter any problems.
