Topic: wrt400n, all atheros design, is this interesting?

I know new router designs by linksys aren't normally very interesting around here, but perhaps this one is interesting?  I have to admit, I'm not very familiar with atheros support...

Internal Details

I already did a detailed review of the 400N's insides (along with the new WRT320N and WET610N). The 400N is a complete redesign of the 600N, using an all-Atheros design including an AR7161 600 MHz Wireless Network Processing Unit (WNPU), dual-band AR9220 and single-band AR9223 single-chip draft 11n radios, AR8216 10/100 switch, 32 MB of RAM and 8 MB of flash

We have support for several AR71xx based devices already, so this one would be interesting.

Re: wrt400n, all atheros design, is this interesting?

I ordered one via my work.  Will crack it open and hunt for serial when it arrives.

Re: wrt400n, all atheros design, is this interesting?

Great! I'm waiting for a bootlog then. wink

Re: wrt400n, all atheros design, is this interesting?

It also looks like it is Linux based since the firmaware is availible on Linksys GPL site.

According to SmallNetBuilder who have reviewed the device the performance should be really good. It's a shame though that it don't have an USB port.

Re: wrt400n, all atheros design, is this interesting?

The linksys board appears to be a very slightly modified reference design by U-Media. They basically swapped out the gig switch for a 10/100 and removed the USB port.

It should be running U-Boot and Linux.

It's a fast sucker, that's for sure.

Re: wrt400n, all atheros design, is this interesting?

This is all good news so far.  What about the wireless chips?  Is there any chance of them working?  ath9k driver I'm guessing.

Re: wrt400n, all atheros design, is this interesting?

Ok, I have finally found a few minutes to rip open this router.  I managed to break everyone of the plastic clips.  I think the serial port is fairly well marked.  I'll try to get some high res photos later as well as some dumps...

Re: wrt400n, all atheros design, is this interesting?

Looking forward for it smile

Re: wrt400n, all atheros design, is this interesting?

This looks like the best thing since sliced bread! smile I wish I could get my hands on one of those...

Anybody know where I can buy one in Europe?

Re: wrt400n, all atheros design, is this interesting?

Alright, here is the boot log.  I will post the pictures later tonight, dinnertime now...

So am I missing something?  Is this thing junk?

I've been trying to figure out how to try a tftpboot, any pointers?

Hi,

This  thing is not junk, although it is just not yet supported.

I've been trying to figure out how to try a tftpboot, any pointers?

Well, if the tftpboot is working in u-boot then you can try an image without flashing anything.
You should build a ramdisk image, then try:

setenv serverip 192.168.1.254; setenv ipaddr 192.168.1.1
tftp 0xa0800000 openwrt-ar71xx-uImage-lzma.bin; bootm 0xa0800000

Regards,
Gabor

Re: wrt400n, all atheros design, is this interesting?

Thanks for that.  The tftpboot does seem to work:

Re: wrt400n, all atheros design, is this interesting?

How do I include the ag71xx driver in the firmware?  I am not seeing it in dmesg.  I also cant seem to find it in menuconfig.  I am using the ar71xx/ar913x target, and the default profile (no wifi) profile.  Perhaps its included but not correctly detecting the switch?  Is there a way to tell if its in the kernel?

Re: wrt400n, all atheros design, is this interesting?

Been looking at the build log, it looks like the ag71xx driver was included in my build.  I noticed the 'cat iomem' doesn't list any mii_ctrl devices like yapoo listed here: http://forum.openwrt.org/viewtopic.php?id=17975

root@OpenWrt:/proc# cat iomem
00000000-01ffffff : System RAM
  00060000-00226c4b : Kernel code
  00226c4c-00279b9f : Kernel data
18020000-1802ffff : serial8250.0
  18020000-1802001f : serial
18040000-1804ffff : AR71xx GPIO controller
root@OpenWrt:/proc# cat ioports
root@OpenWrt:/proc#

I'm going to pull the GPL sources and see if that helps...

Re: wrt400n, all atheros design, is this interesting?

I now have ethernet working, and I also copied in the settings for LEDs, Buttons, and MTD partitions and tried to create the correct support files.  I have tested ethernet, LEDs, and buttons, they are working fine. 

I suppose the next step is to flash the firmware onto the chip?  Whats the trick for doing that in u-boot?

       Say 'y' here if you want to enable special support for the
       Atheros AR8216 switch found on some boards.

Hi,

I now have ethernet working, and I also copied in the settings for LEDs, Buttons, and MTD partitions and tried to create the correct support files.  I have tested ethernet, LEDs, and buttons, they are working fine.

Congratulations.

I suppose the next step is to flash the firmware onto the chip?  Whats the trick for doing that in u-boot?

Here are some info, although it is for a different board.

Can you send this patch for me via e-mail?

Re: wrt400n, all atheros design, is this interesting?

Any updates on this or other attempts on getting OpenWRT running on the WRT400N?

Re: wrt400n, all atheros design, is this interesting?

Partial support was added to trunk.  (flash partitions, LEDs, and buttons)  I'm still working on the image Makefile so that a usable image is created.  Looks like linksys didn't include the source for the image creation utility, so it may not be possible to flash via the stock web interface.

Re: wrt400n, all atheros design, is this interesting?

Is that a JTAG connector next to serial?  Certainly looks like it.

Interesting the serial is 4-pins, guess they have finally dropped the NC pin that has been hanging around forever.

Think it's worth ordering?  I have a WRT610n that is sitting on the shelf collecting dust at the moment.
I'd like a new project to fiddle with if there is SOME hope of getting at least basic 802.11abg working on it.
I'd gladly settle for at least basic working dual-band since I have 802.11abg clients in my house
no 802.11n as yet nor as yet any particular drive to upgrade.  I prefer 802.11a for lower interference
from neighbors so my clients connect preferentially to the 802.11a SSID.

Re: wrt400n, all atheros design, is this interesting?

I haven't even gotten to try ath9k yet, will try after my next image build.
