Das Programm WRTJTAG

WRTJTAG ist ein Befehlszeilen-Programm. Das bedeutet, es verfügt nicht über eine grafische Oberfläche, welche mit der Maus bedient werden kann. Vielmehr werden die Anweisungen in Textform eingegeben.

So öffnen Sie eine DOS-Box: Unter Windows 95, 98 oder ME klicken Sie im Startmenü auf "Ausführen" und geben Sie "command" ein. Unter Windows NT4, 2000, XP, Server 2003 oder Vista klicken Sie im Startmenü auf "Ausführen" und geben Sie "cmd" ein.

Diese Anleitung geht davon aus, daß sich das Programm WRTJTAG im Verzeichnis C:\SKYNET\WRTJTAG befindet. Nach dem Öffnen der DOS-Box unter Windows befindet man sich meist nicht im gewünschten Verzeichnis sodaß man erst dorthin wechseln muß:

D:\Skynet>c: (Enter)
C:\Dokumente und Einstellungen\Skynet>cd\SKYNET\WRTJTAG (Enter)
C:\SKYNET\WRTJTAG>

Wir befinden uns nun im Programmverzeichnis von WRTJTAG. Starten Sie zum Test einmal das Programm:

C:\SKYNET\WRTJTAG>wrt54g (Enter)

NOTES:  1) If 'flashing' - the source filename must exist as follows:
           CFE.BIN or NVRAM.BIN or KERNEL.BIN or WHOLEFLASH.BIN

        2) If you have difficulty auto-detecting a particular flash part
           you can manually specify your exact part using the /fc:XX option.

        3) If you have difficulty with the older bcm47xx chips or when no CFE
           is currently active/operational you may want to try both the
           /noreset and /nobreak command line options together. Some bcm47xx
           chips *may* always require both these switches to function properly.

        4) When using this utility, usually it is best to type the command line
           out, then plug in the router, and then hit <ENTER> quickly to avoid
           the bcm47xx's watchdog interfering with the EJTAG operations.

***************************************************************************
* Flashing the KERNEL or WHOLEFLASH will take a very long time using JTAG *
* via this utility. You are better off flashing the CFE & NVRAM files     *
* & then using the normal TFTP method to flash the KERNEL via ethernet.   *
