A few days ago i had the (dumb) idea to test the 2.6 build from the current development branch
on my ASUS WL-500g deluxe.

The result is a now bricked wl-500gx.
But as you can see on the dump from the serial console, the bootloader seemd to be intact till the first reboot.
Since then NOTHING happens on the serial console anymore.
All i got when i do a power cycle ist a shot light up on the network leds LAN1-4 and WAN
POwer and AIR did not even light up.

Seems the flash including the bootloader is totally erased or corrupted.

The deluxe unit seems to lack a JTAG Port.

So does anybody have an idea what else can be done to unbrick the unit .
Probably some hints whether and how it ist possible to add a jtag port.

anny suggestions more than welcome

this is what i got on my console:

Flash via the CFE and the serial console.

Should be work similar as described for the WGT port under "1. Status of OpenWrt"

http://wiki.openwrt.org/OpenWrtDocs/Har … ar/WGT634U

Hey,

thanx for the answer,

BUT there is NO CFE anymore.

When i switch the power on
there is NO output on the serial console
no possibility to ping the unit

:-(

From where you got the idea that you can use 2.6 for Asus WL500dx?!
Very bad idea. The flash driver is not ready for Linksys WRT54GS/G or any other model than Netgear WGT634u.

That is the reason, we call the tree: DEVELOPMENT TREE. If you do not communicate with the developers, you should not use any
DEVELOPMENT version on your router.

Get a new unit and do not play with stuff you do not participate.

From nowhere - that's why i called it a bad idea ;-)

Well i did in no way acuse you of anything.
You all do great work and this was definitely my fault.
It  was not my intention to blame you of anything.

But i guess the question if it is possible to add a jtag connector to a wl-500gx
IS of common interest.

BTW i know i use the Development branch
        i know what a development branch is
        i know of the risks
        i already once offered to participate but obviously no one was interested
       
BTW a ASUS is a nice Brick much nicer to put it an top of you letters than a linksys :-)

It's currently _unpossible_ to get a JTAG working on the Asus WL-500g Deluxe.

It even don't have any pin outs from the processor the the JTAG adapter.

Today I started working on 2.6 for brcm boards again, and flashed my WRT54GS v.1.0 with a new image.
I can't believe that the box is dead. I still can push "strg-c" and get into CFE. Same should be possible on your router.

Why CFE can't be overwritten?

long story:

CFE on Asus WL500g deluxe is 256 kb in size. CFE on Netgear WGT634u is 364 kb in size. CFE on Netgear use the ELF binary format to
load the linux kernel. (more exactly in our case, the LZMA-Bootloader, which finally extract and load the LZMA compressed kernel)

The LZMA bootloader in front of the snapshots are in ELF format. Asus WL500g deluxe use TRX format to find the LZMA bootloader.

That is the reason it stopps at   Starting program at 0x80001000, because the CFE bootloader on Asus do not recognize ELF.

BUT, if OpenWrt never starts up, it can't use the mtd tool to accidently erase any areas like CFE. I think you should check your cables.

Serial output should still work. Otherwise send me the "dead" box.
