Herr Doktor, schnell!!!

Heute hatte ich eine kranke Dockstar zur Wiederherstellung von einem Freund bekommen. Erst dachte ich, dass er bei der Debian-Installation den gleichen Fehler wie ich gemacht hatte. Ich hab ja bei einem Befehl nur einen Teil kopiert (selbst für Copy&Paste zu doof?). Er hatte aber ein anderes Problem. Seine Dockstar hat brav den Kernel gebootet, aber dann kein RootFS im NAND gefunden.

Das stellt sich natürlich erst raus, wenn man an die serielle Konsole der Dockstar kommt. Die befindet sich im inneren des Gerätes und benötigt ein spezielles Kabel zur Umsetzung der TTL Level auf RS232. Das geht z.B. mit einem USB2Seriell Kabel für ein Nokia Handy, welches als Konverter-Cjip den PL2303 von Prolific nutzt. für diesen Chip gibt es sogar Windows 7 64Bit Treiber.

Zurück zur kranken Dockstar. Diese hatte ja wie gesagt ein Problem, das Root-FS zu finden.

Also mussten die letzten Schritte der Debianisierung nochmals gemacht werden. Um das aber machen zu können, musste erst mal das Root-FS vom Stick geladen werden. Der Kernel kam dabei sicherheitshalber vom DHCP Server. Mein Freund hatte nämlich auch was von einem Schreibfehler beim schreiben in den NAND Speicher erzählt.

Zum booten kann man, nachdem man sich über die serielle Konsole verbunden hat, den Autoboot unterbrechen und selbst die benötigten Einstellungen setzen und dann vom DHCP Server booten.

setenv bootargs $(console) root=/dev/sda1 rw rootdelay=5 $(mtdparts)
bootp 0x800000 uImage
bootm 0x800000

Jetzt bekommt die Dockstar den Kernel vom DHCP Server und nutzt /dev/sda1 (also den USB-Stick) als Root-FS. Dann kann es mit dem Schreiben des NAND weitergehen. Konkret ging es dabei um folgende Zeilen:

flash_eraseall /dev/mtd2
ubiformat /dev/mtd2 -s 512 -f /ubi.img -y
flash_erase /dev/mtdblock1
flash_eraseall /dev/mtd1
cat /boot/uImage > /dev/mtdblock1
wget http://plugapps.com/os/pogoplug/uboot/blparam
chmod 755 ./blparam
./blparam
./blparam bootargs_ubi='ubi.mtd=2 root=ubi0:rootfs rootfstype=ubifs'
./blparam bootcmd_ubi='nand read.e 0x800000 0x100000 0x300000 ; setenv bootargs $(console) $(mtdparts) $(bootargs_ubi) ; bootm 0x800000'
./blparam bootcmd='run bootcmd_ubi'

Nach einem Reboot mit abgezogenem USB-Stick bootet die Dockstar jetzt den Kernel aus dem NAND und findet auch das Root-FS. Operation gelungen, Patient lebt.

PS: Die Installationsanleitung stammte von skorfulose.de.

PS^2: Wer eine defekte Dockstar hat und diese wieder in einen lauffähigen Zustand versetzen möchte, kann mich gerne kontaktieren. Gegen Übernahme der Portokosten für den Hin- und Rückversand und eine kleine Aufmerksamkeit (Gute Schoki o.ä.) versuche ich gerne mein Glück bei der Wiederbelebung.
