Thanks to Eko
As there where always the same questions, i decided to start a page who tells in general how you can get your Broadcom based device running DD-WRT.
Compatibility
There are a few things to be figured out before we start. We/you need to know if its possible to run DD-WRT on it!
- check the Supported_Devices page if your device isnt supported already!
Please do the following check list and if one point fails your device will be not able to run DD-WRT!
- check the Known_incompatible_devices page and read it carefully. if you device is listed or fits into the incompatibilty information...you´re out of here
- open the device and check if it´s Broadcom based (cpu) or is there the FCC-ID printed on a label? check on FCC.gov with the FCC-ID if your device is Broadcom based (internal pics)
- open the device find the flash chip. check out the chip @ Datasheet Catalog and if its <2MB, you´re out.
How to start?
Now that we know that the device is able to run DD-WRT you should do this:
check with a forum search if the device isnt already requested!
if not, start a new topic @ the forum with the subject: "your device with revision" give us all info we need for starting
- FCC-ID
- internal high res pics of CPU, RAM, FLASH, PCB
- maybe RAM/FLASH size and type and CPU type if already known
and if possible
- cfe.bin & nvram.bin via JTAG-Adapter (CFE_backup#by_JTAG)
- serial output
if you have already running a 3rd party firmware (dd-wrt, svesoft, openwrt,...) you can try this to get the cfe: CFE_backup#by_telnet.2FSSH
only if you are instructed to flash a special dd-wrt version for inital flash and it will not brick your router plz give us cfe which is quiet easy as you see here: CFE_backup
In both cases from above you can get a copy of the nvram if you da a "save settings" and name it nvram.bin
We finally installed DD-WRT but no reset button/led working
This page describes how to detect the correct GPIO´s for LED and rest button when you have a device which is WIP for running DD-WRT.
Detecting reset Button
1. telnet in and then...
try to find gpio for the reset button.
gpio poll number from 0 to 8. e.g. Code:
gpio poll 1
Then press the reset button in and out and look for changing numbers.
Detecting LED´s
1. telnet in and then...
try to find for the LED´s
gpio enable number , gpio disable number
e.g. Code:
gpio enable 1
or
Code:
gpio disable 1
go from 0 to 8
If router stop responding, just power cycle it.
List your findings at the post/to the person who asked for it!
