Kernel Build, native on DockStar
In order to adjust the selection of drivers to include in the Linux kernel, you have to build the kernel by yourself. See here: Howto: Build a new Debian kernel with LED support http://forum.doozan.com/read.php?2,524,page=1
Kernel 22.214.171.124-kirkwood date: 2010-01-22 was the initial kernel
Kernel 126.96.36.199-dockstar date: 2010-08-26 uses the DockStar LED
- Kernel 188.8.131.52.3-dockstar date: 2010-10-26
- fixed contrac sisusbvga(+consoleswitch), ntfs(readonly), hfs hfs+ support
- usbgadgets added, automount fixed, add i2c code
new kernel package ready to use, from gorgone http://forum.doozan.com/read.php?2,582,page=1
at least from kernel 2.6.34 on, in /boot an uInitrd (initial Ram Disk) is no longer needed. The config file for download on page 6.
Andreas posted infos to the long term kernel 3.0 http://geekparadise.de/dockstar-kernel/
Ubuntu 12.04 uses for the Long Term Edition kernel 3.2.0.
At the moment it is not clear which newer kernel is good supported (2012-08-29).
In the forum, 2012-07-14 a new install script is posted from Jeff.
See Debian wiki. It is a development version with long term kernel 3.2.
- You need to read the whole thread to avoid pitfalls!
- $ uname -a
- Linux dockstar 3.3.2-kirkwood-dg #1 Mon Apr 23 17:09:27 CDT 2012 armv5tel GNU/Linux
But you need a new uboot
But you need a new Rescue system V2/3
It looks like to better not use it now for the Dockstar (2012-08-29).
In order to have no need to patch a standard kernel for a little deviation, like the LED support for the DockStar, you can register an arc number at http://www.arm.linux.org.uk/developer/machines/.
The arc number for the DockStar is 2998.
A more detailed description of the arc number is at http://www.plugcomputer.org/plugwiki/index.php/ArcNumber. This arc number must be set in the boot loader.
10/23 - New uBoot - GoFlex Net support + new 'arcNumber' variable from Jeff
http://forum.doozan.com/read.php?3,1893,1893,quote=1 This variable is the first step in moving toward using proper machine IDs. However, the machine ID specified in uBoot also needs to be supported by the kernel that you're using. Since there are still a lot of kernels out there that have Sheevaplug support but not Dockstar or GoFlex support, the installer will continue to use the Sheevaplug ID.
If you're running a kernel that supports your device, you should set the proper machine ID by running 'fw_setenv arcNumber 2998' (on a Dockstar/Pogoplug) or 'fw_setenv arcNumber 3089' (on a GoFlex) and rebooting.

In order to change the arcNumber to DockStar do the following:
$ sudo fw_setenv arcNumber 2998
Getting the Source Code
The source code can be found: http://www.kernel.org/pub/linux/kernel/v2.6/linux-184.108.40.206.tar.bz2 (66 MB)
Version 220.127.116.11 is from 2010-11-22. Because Version 2.6.36 is out by 2010-10-20, it can be assumed that version 18.104.22.168 should be stable.
Setup for compiling
Native compiling on the DockStar does also work now, about 2.5 hours total.
apt-get install git-core debhelper build-essential fakeroot kernel-wedge uboot-mkimage additional apt-get install libncurses5-dev # for make menuconfig
