I couldn't find this anywhere, so thought I'd post it once I found it.

The e4200v2 is Marvell based, and there are serious reservations on dd-wrt landing on those units because of binary blobs being published instead of real and true GPL source code.

But I was able to connect to the serial port on my e4200v2 and capture its bootup (using my arduino uno...it was actually not hard once I figured it out).

The serial port is on section J5 and transmit is pin 5 of 6 (5th furthest from the super bright LED on this unit)

Oh...forgot one more thing.

Baud settings were 115200 8 none 1

Now that I have a serial console then I can start beating on this unit more thoroughly.

I was able to solder my headers on....as referred to before:

TX=pin 5 of 6 (starting from bright LED)
RX=pin 3 of 6
GND=pin 6 of 6 (or any other good ground spots on this board...there are many if you want to break out your multimeter)

Version of linux is NOT stripped down, I found all the tools I really need (wget, find) already installed. Theoretically I could compile anything new I need by using the source code & toolchains supplied by LinkSys....

I was able to interrupt the Marvell U-Boot process by hitting spacebar immediately upon powering on the unit. Make sure you are properly grounded to the board or this may not work.

By chance, could you rebuild the original firmware to update some components? (like libupnp, twonky media server, wifi drivers, etc.) Also removing the old Cisco logos in favor of the new Linksys ones and the Router Properties pages is messed up

What about taking features from the WRT1900AC and porting them to the E4200v2? (like Network Map, Wireless Bridge & Wireless Repeater)

Thank you

I'm going to focus on OpenWRT on this unit. They have already supported the Marvell Kirkwood architecture.

I haven't received any response yet on my post on the OpenWRT forum yet though....

https://forum.openwrt.org/viewtopic.php?id=51208

As far as rebuilding the stock firmware, I think that will be a little harder than first thought. The stock firmware source has none of the image packaging built in, so it build the binaries but doesn't arrange them into an image. It is basically a dump of the developers' build environment without good notes and all types of build customizations.

I need help on the OpenWRT side so I can install a kernel that boots. I'm pretty sure my boot options are wrong, but I think the u-Boot won't load newer 3.2 kernels.

This is exactly what I need, what pin did you use for GND? I am trying to debrick a e4200 v2 right now, stuck in a infinite boot loot :/

if you still have your board hooked up you should get a picture since language barriers and what not would be helpful for the world Very Happy

Try this OpenWRT image:

http://www.wolfteck.com/projects/candyhouse/openwrt/openwrt-kirkwood-ea4500-uImage-initramfs

I built it based on the work of Jogo and Luka. I've run this image on my personal Candyhouse routers.

I have a bunch of info (including pictures of the serial setup) and there's quite a bit of discussion on my project site:

Thanks
