Unbricking with no TFTP

Hi,

Well I have managed to sucessfully brick my WGR614L (European Version).  When I say bricked, I mean really bricked!  At power on I get a constant Power and Self-Test lights! (So no TFTP recovery for me).

I am assuming I am in for some bit banging over the JTAG at this point. Does anyone have any pointers to the pin out, and preferably the correct image to upload?

I would also like to work out where I went wrong!  I downloaded the source code for the Independent Firmware Build (4.139.6.2) and the tool chan (for the v8) from netgears main site.  After a little fiddling (paths broken etc) I managed to get it to build.  I then followed the instructions in Nachi's blog about Firmware Image Creation (given that I have seen that the european version required the lzw images).

I am in the process of adding sorting out the console - not that I expect to see anything!

Any help would be greatly appreciated!!

D.

Nachi has published a Tomato

Nachi has published a Tomato image for the europian version. You can download the firmware from http://www.myopenrouter.com/download/10413/tomato_wgr614l-lzma/ and try that out... Good Luck.

Well its not as bad as I

Well its not as bad as I thought! After a little soldering I can confirm that the bootloader is still intact!

So if anyone else gets Power and self test just on, then its worth getting a console going...

Still not sure what is wrong with what I have compiled, thats the next task. However this is what I am seeing, which would suggest that what I uploaded is just broken!

I will give that a try.  Unfortunatly pre-rolled images are not going to cut the musterd for me - although it is at least a starting point.

It my intention to get the reference design working, and from there make the chages I need.  I could diverge from another tree, Tomato/DD-WRT/Netgear, but I would much prefer to start from the reference design.  So if you have any hits about where I am going wrong I would love to hear them!
