Normally you should be able to manage the dockstar over the ethernet, but what if you can't establish no connection because you did something wrong? There is a serial connector inside the device we can use for debugging and other things.
1. Required: USB to TTL bridge
Some weeks ago I ordered an USB to TTL UART bridge on eBay, just to have it if I will need it. You also can buy it on amazon: USB2.0 an TTL UART 6pin Konverter seriell CP2102 ID9372 PAUB022
Here are some technical specifications of the one I bought:
All handshaking and modem interface signals Data formats supported: 8-bit; 1 Stop bit Parity: Odd, Even, No Parity Baud rates: 300 bps to 921.6 kbps 512 byte receive buffer; 512 byte transmit buffer Hardware X-On/X-Off handshaking Event character support 6 Pins: 3.3V, RST, TxD, RxD, GND, 5V
When I was trying to find proper kernel configs for the dockstar, I had to try several builds. Everytime my kernel didn't boot I had to revert the arcNumber and install a working kernel again.
There are two ways to test a kernel:
- Grab another USB stick, make a backup and try the kernel on this backup. If you always do a new backup before testing another build, it will take a long time.
- Test the kernel on the running system (or a backup-stick) and reinstall another kernel in case yours wont boot. In difference to 1. you do this in a chrooted jail.
I want to explain how you do the chroot thing with some lines.
During the last days I was playing around with several kernel-configs and different release versions. Today a new version came out and I built it with the last config I used. In my build I additionally enabled XFS filesystem support and USB sound. If you install my kernel, you don't have to change anything except the device ID concerning the LED if you come from gorgone's heavykernel.
If anybody knows how to build a kernel with gspca drivers for webcam support I would appreciate a short mail!
Some days ago I wanted to test the performance of a partition with XFS as its filesystem. But I wasn't able to mount it. After a look into the kernelconfig of gorgone's heavykernel I noticed that he obviously didn't build it with XFS-support.
I do want to make the test and take a look at kernelbuilding things anyway. Well, I don't want to keep it back, so I decided to verbalize the steps I took.
In this guide you will learn how to set up the crosscompile toolchain to let a more powerful CPU do the job. If you prefer doing the whole thing on the dockstar it will take you several hours.
Further more we will go through the build process until we have a deb-file with the built kernel.
Auch mir ist aufgefallen, dass mein Defy oft die Verbindung verliert wenn eine Fritz!Box 7270 mit eingeschaltetem 802.11n benutzt wird.
Bei meiner wöchentlichen Beschau einiger Blogs bin ich auf einen Beitrag von dev-eth0 gestoßen, der WLAN-N im Handy abschaltet und so das Problem umgeht.

It's been some days now when I got my dockstar and I've been reading along the web to get more and more information about how to get debian to work with the dockstar. There are a couple of HowTo's out there, but I had to check at least a few of them to get to know what I wanted to know. So I decided to make my own HowTo as kind as a merged one with everything important in it.
Of course the first step was to unbox the little homeserver, but the second one, the most important step if you are going to put it online is to disable the Pogoplug software before you connect it to the internet by simply disabling the autoupdate on the NAND. You have done this already? Skip to part two!
Well then, you have to go offline, yes your wan-interface must go down.
