Topic: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

I'm finally playing around with newer Broadcom hardware. I have a couple Cisco E3000 and even managed a workable serial port tap off the WAN pads without soldering!

UPDATE: Reports are now also that the Belkin PlayMax F7D4301 is the same Broadcom chipsets too. So we have four routers all with similar firmware compatibility.

UPDATE: January 3, 2012 there is recent activity on the patches!! I See: http://www.znau.edu.ua/temp/asus-rt-n16/openwrt-bcm4716-README.txt

Anyone running newer trunk? Are these patches making it into the OpenWrt development tree?

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

the problem is the GMAC driver not covered by GPL.
I believe it's too much work for someone to write the whole ethernet driver.
I don't think it will be supported officially by openwrt.

Thank you for this pointer. I now find this: https://lkml.org/lkml/2011/4/12/499
"UNPUBLISHED PROPRIETARY for GMAC core driver sources (etcgmac.c)"

And copyright discussion, and how the source is out there, but the header implies proprietary:
http://www.spinics.net/lists/linux-wireless/msg69217.html

Open ticket, which mentions the license issue, on OpenWrt
https://dev.openwrt.org/ticket/6580#comment

Can we flash a OpenWrt driver combination that is missing the LAN support?  Just the wireless, flash, USB... one could drop in a USB ethernet driver as a short-term solution to use it as an Access Point....

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

In the USA, right now reputable Newegg has the Asus RT-N16 for $47! http://www.newegg.com/Product/Product.aspx?Item=N82E16833320081  - see if you can snag a free "ShopRunner' subscription for 2-day free delivery.

The Asus has double the RAM of the Cisco and 4x the flash! However, it has only one radio, the Cisco has a second chip for 5Ghz.

Unit RAM = 128 MB (2x 64MB - Samsung K4N511163QZ-HC25 or 2x 64MB - Samsung K4T51163QG-HCE6)
Unit Flash = 32 MB (MACRONIX MX29GL256EHTI2I-90Q)

Sure. email me your address information to stephen @ hilltx.co.m - I'll reply back. I'll power it up and make sure it works before I ship to you.

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

Ok, I've been compiling trunk against the latest patches I could locate on http://www.znau.edu.ua/temp/asus-rt-n16/ and build starts to break in USB patches on r29264 "linux: update 3.0 to 3.0.9"

It looks like Broadcom SSB EHCI support was added to OpenWrt trunk on r29264 http://dev.openwrt.org/browser/trunk/ta … ?rev=29264 - and that the patches conflict.

This is all 5 weeks ago that r29264 conflicts were introduced.  I see recent activity, from 1 week ago, here: http://patchwork.openwrt.org/patch/1676/  these seem to be focused on some Netgear routers ( WNR3500Lv2 & WNDR4500 ?)

Anyone want to help me out on getting a current trunk patch set? I'm slow at learning all this wink Still playing around with this code...

Ok, I got past those two problems.  Now I'm finding:

./build_dir/linux-brcm4716/linux-3.0.4/patches/platform/0001-bcma-move-parsing-of-EEPROM-into-own-function.patch

Fails on current trunk. Trying to figure out why.

Hey, I have your Asus router here wink  Send me your address and I'll try to get it out Tuesday.

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

i'm sorry for misunderstanding, i thought the're out of stock and i bought a seagate dockstar instead - to "play" with.
and already have a rt-n16 since 2 years ago - but it's productive (tomatousb).
i wanted another one to try out openwrt and debwrt - but it'll have to wait - my Christmas presents fund is gone.
Thnaks and Merry Christmas  !

Round sparrow have you made any progress getting the newest openwrt trunk to build? I've been following this thread.

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

@RoundSparrow If you still have the router, I'm interested in it! Thanx!

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

George Kashperko has posted new patches as of 01/01/2012. They work against the current trunk version.

Cool, I'll try them out shortly.  I do now have both the Asus and Cisco E3000...

Both the Asus and Linksys stock firmware are vulnerable to the WPS PIN attack... more reason to shift to OpenWrt smile

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

There is work going on now to reverse engineer the gmac core: http://bcm-v4.sipsolutions.net/mac-gbit
It allows for a clean-room implementation of a new ethernet driver.

Cool wink

here are my notes so far on the latest patches (files dated 2012-01-03).  I checkout into a directory called openwrt - so i do some sed changes to normalize the paths in the patch files.

It is working pretty good so far. I was able to make the router an Access Point using WPA2 encryption using LuCI.  If anyone else wants a copy, here is the Cisco Linksys E3000 binary for R29644 (the bootlog shown in this post), LuCI included: https://sites.google.com/site/stephengu … uashfs.bin

We tested the router as an Access Point at our Austin Linux meeting tonight. Seems to max out wireless throughput around 1.5Mbps... pretty crappy. This was from various client 802.11n systems, 4 active ones. CPU was not maxed out, so not sure what is going on with the wireless driver.

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

I get an error with the patches. Can anyone help ?
I noticed sed 's/+++ openwrt.r29637/+++ openwrt/g' 001-openwrt4716-TARGET_brcm4716-F7D4301-fix.patch. In George's patches there is no reference to r29637.

Perhaps you used the wrong -p or --strip option?

Re: Linksys Cisco E3000 v1 / WRT-610N v2 / Asus RT-N16 hardware on trunk

development for brcm47xx is advancing faster than george can patch things up - last change 4 days ago.
but i believe that he'll come back with a new set of patches soon.
if you want to compile it - try pulling older sources  - latest update on george's repo was on 9.01.2012 - so sources < 29700 should be able to compile without errors.
that's only my guess - if you want it - try it - i t might do it in the weekend and report back
