So I dont seem to be getting anything useful out of what I believe to be the JTAG on this board, however there are 4 pins near the chipset that appear to be serial.

When connected to the serial on my TUMPA I get a series of garbage that does respond to my input though I cant read it.

EDIT:

So it seems this is a TTL serial port, when connected to the TTL on the TUMPA I get intermittent text that is legible... things like 'Decompressing' and 'Done' and a few others that I can read here and there, but the rest is all garbage.

Alright, well with my inexperience in doing this and while there is definitely a plethora of information both here and elsewhere, I cant seem to find exactly what is needed to connect to my router in a method beyond the norm, so I'm going to give up on it for now. I've managed to fry 2 different USB to Serial/TTL adapters, not even connecting them the same way. If someone comes back with more useful information I'd be game to try again.

The lack of response to this, and other, threads about this device leads me to believe there isnt much interest outside of my own.

Not the only one, I almost went and bought an adapter too, but I haven't had the time to dedicate to it. It sounds like you're already on the right path, but I've never messed with the JTAG stuff before. Hoping brainslayer could chime in quickly?

...where to start. Can you point me in the right direction on the latter and I'll see if I can look into it, too?

Guys, any update on this one? I just got the device I'm senior cpp developer, may i help you with anything on this?

[Yeitso]

If I get things correct Brainslayer needs the nvram/cfe from the device to begin with. I have no idea on how to aquire this but I have a EA9500 and am willing to help out. I also have a USB -> TTL if that helps.

As far as I know, you need to attach to the JTAG pins on the mainboard, then you can dump the firmware somehow.

I think this is the right starting point:

So something I'm finding out about this router is that the switch chipset is terrible.

I routinely stream uncompressed 720P HD video through my network because I have a Windows Media Center PC and XBox 360 media extenders. Replacing my old router with this one has introduced a continual "network issue" message on the displaying 360. I even tried moving them to the other 4 ports since it is serviced by a separate chip which did not clear the problem. I instead moved them to a standalone switch and it completely cleared up the issue.

In addition I swapped out this device with the WRT3200ACM which also cleared up the issue.

So I'm not sure what the issue is here, but this device clearly has a problem with its switch chipset. The only thing I can think of is that the router has a buffering problem since the Xbox 360s only support 100mbps connections while the PC is gigabit.

I'm just hoping for a build. Is this possible?

[ATHF]

I believe that is what brainslayer was waiting for, hopefully he will see this post. You could post it in the Broadcom forum also.

Does anyone know if this was enough information for BrainSlayer to work on supporting the ea9500? I couldn't find any topics about it in the Broadcom forums. Hoping for ddwrt so I can get rid of Linksys's smart wifi DNS issues.

If you want you can install Lede (OpenWrt offshoot) from here https://forum.lede-project.org/t/build-for-linksys-ea9500/1817

I have this router on order. When I get it, I am willing to help as well...although a newbie to dd-wrt, I am also a techie so not totally clueless

If this router is a total no-go, would be good to know that as well. I can return and get a supported device.

Thanks.

I have this router. Let me know, if I can help out.
