May I ask how did you find these? I am doing the same on ADSL2MUE and surprisingly JP1 looks exactly like the EJTAG interface you describe (GND and Vcc lines do match). But I am not brave enough to connect anything that might break it down. Any advice?

BTW, on your bootloader login request, did you manage to get into it? From what I've read bootloader environment is stored with nvram config instead of being coded into the software itself so having access to read the flash partition should lead you to fin the boot login and password, don't you think? ADSL2MUE has version 1.2 too and ESC key works like a charm.

YDEF -

The pinouts are fine.  Does this TI AR7 chip support DMA transactions?  Also - to get JTAG working - it should be quite easy, assuming the chip's EJTAG support is at 2.0 and not at the 2.5 or 2.6 standard - as those don't support DMA EJTAG transactions.  If so - then the Debrick Utility can be moddified quite easily to support this chip as well.

That layout is a standard layout for certain 14 pin JTAG connections.  Not all maunfacturers will follow the standards - but in this case - it does look like a standard layout.

Building a JTAG cable for this should be very easy.  Check out the Xilinx Type III cables (or look at my guide) - either of which can be adapted quite easliy.

FYI, using the existing JTAG pinout and code for a WRT54G[s].  I'm rechecking a couple things, most specifically the 3am solder job that probably netted a couple cold joints.  Wasn't expecting a 100% match, but did expect to pull something aside from NULL for a chip ID. 

Thoughts? Recommendations?

now would it be posable for me to modofy the unpacked vonage virmware image and then upload that to my router if so how would i repack the image with the few simple modofications that i have made

First off you all rock, and your mostly over my head, but I'm enjoying hell outa reading here.

and I can get to the update page using firmware version 1.00.52.

With only 4/16MB RAM/Flash memory, it really is a hard press to squeeze in a complete Asterisk package. Some people have done so with a minimal/stripped version of Asterisk on WRT54G routers.

[OT]: These days, a Sony Playstation II (PS2), runs @300MHz requires no CPU FAN (very quite), is not very expensive. It can run Linux with a 32MB RAM and lots of HD spaces. IIRC, it's got a 10/100MB NIC and 1.1 USB ports. One can definitely attach a USB->10Mbps NIC adapter and convert this PS2 into a router + Asterisk + SER, etc.

I believe the OpenWRT SDK package can be used to repackage your WRTP54G modified firmware.

Is anyone working to unlock this WRTP54G? The one I have is a virgin WRTP54G and user/tivonpw does not work. Can anyone please tell me if I need to get mine provisioned by Vonage first in order to use the user/tivonpw so I can flash it with the latest firmware?

A wiki page has been started detailing the WRTP54G and RTP300 at:
http://wiki.openwrt.org/OpenWrtDocs/Har … ys/WRTP54G

I'll probably try the auctiontec hacking thing tomorrow or the next day to see if I can extract the mtd memory blocks...

Although it would be a cinch to run nfs to expand fs size and run asterisk from there.

My guess is too that later iterations of this router will not have a seperate mini-pci card as this one has but have it integrated into the board.

This board is kind of like the wrt54g 1.0 in that respect. The first prototype of its kind, with a seperate mini-pci card slot that the ax100 resides in.  If you go to TI's homepage to look up the different models ar7 based voip router reference designs, you'll find that there's also a model with the chip integrated into the board much like more recent versions of wrt54g.  At which point, hardware mods become easier ... such as memory addon via gpio as is available for wrt54g/gs.

You must be talking about a WRT54GP2 and not a WRTP54G unit.

After re-reading this post, I am a bit lost here. What is an upgrade_code.bin firmware file? Is it a hacked firmware that can unlock a WRTP54G unit locked to Vonage?

nope, i'm talking about a wrtp54g.

You should educate yourself on this router a bit by reading up on it in the ar7 section of this site.  Pay particular attention to PSP Boot, which is the bootloader that runs on the wrtp54g.

Also, make sure to read this entire thread from the beginning.

So, now these RTP300/WRTP54G are hacked/unlocked, what is the status on porting OpenWRT + asterisk to run on these routers?

I have just brought a linksys WRTP54G-AU it has the unlocked AU/NZ Firmware.  I would like to back it up. So I can post it here and other places for people who currently have a locked down version of the firmware. And also so when I start playing around with my firmware I can get back to my current firmware. I know I have seen a way posted somewhere that did it from the cmd line but I cannot find it now. I am very familiar with routers and networking and windows but am relatively new to Linux so any guides would be great. I am also keen to know the status of porting openWRT to this router and if there is anything I can do to help with this. Thanks :-)

has anyone tried this option. How do I load the firmware using tftp. My router is locked to earthlink. wrtp54g-er user/tivonpw does not work. f/w is 1.00.48
