WRT54GS v1.1

Post by devDelay » Fri Feb 22, 2008 5:33 pm

Hello. I have a WRT54GS v1.1 that is bricked. USBJtag identifies this as:

IDCODE 1471217F
Broadcom BCM4712
IMPCODE 800904
DMA supoorted
Found Address= 9fc00000 Intel 28F640J3

When writing CFE I must erase and then use sprogram for it to appear to write. However when finished it doesn't appear to do anything. CMPRAM is useful to let me know for sure this is true.

-sprogram cfe
Program Starts...
Program time 00:01:02 .081
-cmpram cfe
Compair data Failed address 9FC00000,target 00,PC memory 17

I was told by a friend that this has been acknowledged as not actually able to write data. Is there any kind of fix for this?

Which version of software you are using? There are certain version of software that will cause some problem. If you use 0.21 you should have less trouble.

I am using .19. I have downloaded version .21 but I don't see how that version will help the situation. The problem is the usbjtag.def for the WRT54GS. This WRT54GS has a 8MB flash for the Intel 28F640J3 controlled by a BCM4712 so it is a bit different than the definition written in by default. Any assistance editing this would be much appreciated. Thanks.
