Ich entleihe mir hier von Alexander Holler mal die Pin-Belegung des Pin-Headers im Seagate FreeAgent DockStar:
9 7 5 3 1 10 8 6 4 2 RX TX GND 3.3V!
Hintergrund: Ich versuche nun dann doch, mal über dokumentierte Wege den DockStar zu einem Multi-Purpose-Gerät zu machen:
[...] bash-3.2# ./pogo_u-boot_install.sh Ready? Press ENTER to start, CTRL-C to quit! Downloading new bootloader and verifying it... Writing new bootloader... Setting new boot configuration... What device are you installing on? Type only the number of your device and pres. 1. Pogoplug v1 - Brick 2. Pogoplug v2 - Pink 3. DockStar 3 Writing DockStar Bootloader... Installation is complete. Continue by installing Plugbox Linux to a USB drive. Reboot with '/sbin/reboot/' when you are ready. Your LED will be red, organge, or off completely when booting Plugbox. Just in case you chose the wrong device, just re-run the installer.
… allerdings noch mit meinem eigenen uImage:

WTF? Ah, super; mein sda1 ist /boot und sieht so aus:

Hachja. mit »cd /tmp/.cemnt/mnt_sda1; ln -s . boot« also nochmal probieren ;)

Naja, noch nicht ganz das, was es werden sollte, aber immerhin, es bootet schon mal wieder durch in ein Linux ;)
