Topic: Netgear WNR2000 OpenWRT (Atheros AP81, AR9103 chip, u-boot)

The content of this topic has been archived between 3 Apr 2018 and 3 May 2018. Unfortunately there are posts – most likely complete pages – missing.

thought this device needed own thread here, it has experimental support in current OpenWRT.

Some facts:
* The factory firmware is based on a fork of OpenWRT WhiteRussian with kernel 2.6.15.  There is a way to get root telnet on the device with the factory firmware if you wish.
* u-boot is wide open on this router, you can connect a rs232 serial port and u-boot has a 5 second countdown to take control.
* Atheros AP81 hardware platform.  I have removed the RF shield and visually confirmed the radio is an AR9103 chip, which is 3x3 MIMO.
* Router has a tftp recovery mode if you corrupt the firmware.  details below.

Right now there is no firmware that you can flash, I have been using u-boot tftpboot and ramdisk image of OpenWRT.  Testing the newer AR91xx support in ATH9K driver.

Photos of the router hardware: http://www.smallnetbuilder.com/content/view/30615/96/


PROBLEMS and Status OpenWRT
======================
1) NO WAY TO FLASH OpenWRT.  The bootloader does a checksum of the flash contents so we have to overcome that to flash OpenWRT onto the router.  If flash filesystem modifies contents, will be different each boot.  Solution may be to modify the u-boot on this router.
2) Current build of OpenWRT doesn't enable the Ethernet ports, so you only get WiFi.
3) ath9k driver slow.  See the Trendnet TEW-652BRP thread for other details about current issues with the AP81 platform and performance with ath9k driver.


Firmware Recovery
================
Experimenting with flashing, I've managed to mess up the firware a few times.  Good news is you can recover it.  If you hold down reset (for like 30 seconds) while you turn on power to unit... it goes into tftp recover mode.

In recent builds of OpenWRT, the cabled ethernet ports stop working for me.  OpenWRT SVN 13658 I had working ethernet ports.  Output:

Good news is the ATH9K driver is working!  I was able to connect a client and ping the router.

(Last edited by RoundSparrow on 5 Jan 2009, 01:46)

The ATH9K driver is confirmed WORKING on this router with AR9103 chip!  I had to reverse out the recent crypto change (SVN 13850) to resolve error I was having, but after that - SVN 13865 works!

1) LAN ports are not working as noted above, they were working in SVN 13658 but not in 13865.  Any ideas?
2) Currently no way I know to flash this router with OpenWRT, only able to boot via u-boot tftpboot

Thanks again Gabor for the ath9k driver work!

Fixed in trunk already.

Without the 'board=WNR2000' bootarg you have used the 'Generic AR71xx' code previously, and the WNR2000 specific setup code don't register ethernet devices yet. I will copy it from the generic code tomorrow. I have no ideas about the WAN port yet.

2) Currently no way I know to flash this router with OpenWRT, only able to boot via u-boot tftpboot

This requires some work yet.

Thanks again Gabor for the ath9k driver work!

You are welcome, however you will owe me with the bounty ;-)

what do you want, let me know which:  1) hardware (routers you don't have i can perhaps find in USA), 2) pizza/beer, 3) cash (PayPal)?  Anyone else pitching in?

Do you know of any AP81 board that has a JTAG header? Because of the way Netgear tweaked u-boot on this device we are going to need to reflash the bootloader when storing a writable filesystem in flash. I'd like to have a similar device with JTAG to test the tweaked u-boot on before I reflash the bootloader on my WNR2000, since I will likely only have one shot if it didn't build properly.

Well, some AR913x based boards would be nice.

Does anybody know of any reasonably priced (i.e. high volume consumer grade) concurrent dual radio (2.4 / 5 Ghz) AR913x based boards? I would donate one of those in a second if there was a chance to see OpenWrt on such a beast. smile

The Atheros AP83 reference board uses the AR9132 SoC and the AR9106 RF chip (Dual Band, 3x3MIMO), and OpenWrt runs on it already:

Although i don't know about any consumer devices with AR9104/AR9106 RF chips yet, but if anyone find one, we will support it sooner or later. :-p

The AP83 sure looks nice, but I was hoping for something AP94-like with two radios that can run concurrently. smile

And it seems TRENDNET have answered my prayers: http://trendnet.com/langen/press/view.asp?id=799 smile

The TRENDnet TEW-673GR employs Atheros’ XSPAN® AR9002AP platform, which consists of the AR9220 and AR9223 XSPAN dual-band radio chipset... The platform also features Atheros’ 680MHz AR7161 wireless network processor and Atheros’ AR8316 Gigabit Ethernet switch to support unsurpassed bandwidth to both wired and wireless clients.

Sounds like stuff that OpenWrt would like, no?

Maybe the Netgear WNDR3700 is similar?

yep indeed. Is there a linux-driver for the switch available?

I've updated the first post in this thread with info on recovery mode.

This router has a way to recover if we do a bad flash - so somebody with experience want to help out in figuring the flash format?  It runs White Russion and root telnet is available, what would I flash on it?

The hardware is similar to the flashable Trendnet TEW-632BRP, TEW-652BRP, D-Link DIR-615 C1. However, has different method of recovery boot and u-boot is modified.

gabor,

I noticed you mentioned that the openwrt is working on the AP83 reference platform.

I'm a newbie, could you give me a couple of quick pointers on how to get this up and running.
I have an AP83 ref platform here.

I'm trying to understand the board/cpu initialization code.

TIA

WNR2000 - I had previously overlooked that we have source code for the u-boot for this router.  So the checksum feature that is preventing us from flashing OpenWRT could be replaced.  Anyone wanting to hack on u-boot wink ?

Also I've looked over the software and such for the Netgear WN802Tv2 (WN802T-200) http://www.netgear.com/Products/APsWire … ifications  - this is an access point.  The firmware clearly has references to AP81 name.  I also notice the the firmware is over 5MB in size, does this Access Point have 8MB of FLASH?

The GPL download for the WN802Tv2 are at: ftp://downloads.netgear.com/files/GPL/

(Last edited by RoundSparrow on 12 Feb 2009, 19:13)

I've downloaded the WNR2000 GPL package from netgear.  It is version V1.2.0.8.  Unpacked it, followed the instruction, but can't compile it.  Turns out, it's missing a lot of packages such as router-gui, dropbear, kmod-ar91xx, and many others.  If I took them out, it builds fine, but the new compiled firmware won't boot.  So you can't just take their GPL offering and make your own firmware.

Were you able to get telnet enabled?  Looking at the code, they use simpleinit.  In order to enable telnet, you have to comment out the part of the code that disables it, build a new simpleinit.

I see there is a wnr2000/stock-rootfs.squash.img on openwrt's download.  I suppose you can extract it from the stock firmware.  How does one do that?

Yes, Netgear telnetenable works fine on this router.

how do you enable telnet (stock firmware)?

I tried that on my wnr2000 but it doesn't work. I notice that my modpkt.pkt file is empty.  My wnr2000 has version V1.2.0.8.  Which version is yours?  Perhaps Netgear has closed this loophole in their latest firmware?

Is anybody know how to make Ethernet work on WNR2000 with SVN 14548 (This is the one I tried)?
I checked out the code in target/linux/ar71xx/files/arch/mips/ar71xx/mach-wnr2000.c, there is no code to setup Ethernet. (There is some code in mach-ap83.c, mach-pb42.c, ..., etc, to setup Ethernet).

Or what type of board should I use which can make Ethernet work on wnr2000 board?

Thanks.

Juhosg has been pretty busy, I think he may have forgotten to copy generic in as he said in the earlier message of this thread.  I understand this uses the same Atheros LAN/Switch chips as the Trendnet and the Planex AP81 routers.  the ar8216 switch chip. Although on the Planex we got WAN working but no LAN ports, as we lack technical details on how to initialize the chips.  No such problem on the Trendnet ones... as Juhosg explained it to me, there are two methods of initializing the chips...

If you aren't afraid to program a little, the file /target/linux/ar71xx/files/arch/mips/ar71xx/mach-wnr2000.c is where these get set.

I assume you are doing tftpboot?  If so, you could skip changing the file and try various setenv bootargs 'board=WNR2000' values and see what works.  possible values I see in prom.c:  TEW-632BRP, MZK-W04NU

Hope this helps.
