Topic: WPN824N opensource

The content of this topic has been archived between 6 Feb 2018 and 27 Apr 2018. Unfortunately there are posts – most likely complete pages – missing.

Okay so netgear has so far been completely useless.
if downloaded the netgear source code for the WPN824N if tried version 1.0.0.28 which failed when building the iptables package. tried verison 1.0.0.22 which compiles but when put on the device i get power green flashing and yellow check flashing.

oh btw yes this source is based of openwrt before anyone says it's not.
RELEASE:=Kamikaze
VERSION:=7.09

after being unable to find the issue with the source or what ever is going on i tried this
http://wiki.openwrt.org/oldwiki/OpenWrt … netConsole

put in the mac address labeled on the bottom as noted in the instructions got no errors or anything but telnet hangs.

from what iv been reading openwrt tells people to go to netgear(that makes since to me) then netgear turns around and tells people to go to openwrt(which doesn't make a whole lot of since) even though they modded openwrt to work on there device.

any advice would be great

I don't know if it makes sense to build a 4 years old openwrt. It runs on kernel 2.6.15 which is pretty outdated. You could add your specific device to openwrt. Your SoC (AR7240) should be covered by the AR71xx, so in best case you only have to copy some config files. See http://wiki.openwrt.org/doc/devel/add.n … rnel.patch for further information.

Ill give it a try. its running 2.6.15 and im gonna start diffing the source supplied by netgear with the the kernel from kernel.org as the how to says.

cool thing is there are madwifi packages for the wireless-n im hoping to turn it in to a jasager router see hak5.org for the wifi pineapple.

Thanks alot MBS

Sorry to disappoint you, but it seems to me that netgear did that already. Just have a look at /target/linux/wpn824n-2.6/src/arch/mips/ar7240. It just happens that in current trunk the ar7240 is part of ar71xx. But as I mentioned already above: it seems to me that all the pieces are already available in current openwrt versions, you just need to patch them together. So I would recommend to copy one of the mach-***.c files found in arch/mips/ar71xx/ to something like mach-wpn824n.c and change it to your needs. Then add it to the Kconfig an Makefile (as mentioned in the wiki) and give it a try.

this is starting to look like something that is beyond my knowledge level.

MBS you seem like you know more about building device specific firmware then i. would you be willing to build firmware for me to test? i can pop my device open and hook up a serial  cable to it for debugging. i just dont have the smarts to convert and move code around.

I'll see what I can do. Though I am no expert and never added any new device before. It is mainly knowledge I gathered by examining existing files. So no warranty.
For the time being, you should hook up a serial cable and get comfortable with the boot loader - it might be necessary sometimes.

i have used uboot. we were doing a project with the literati ereader which used uboot. but ill hook up a serial connector and take a look at it

sounds good. if you've got it working, please post a log from power-on until the system is up and running, and a log when entering u-boot.

here is the bootlog

Can you check (i.e. in uboot) in which memory area the flash is mapped to? I'd like to confirm that the location of the MAC is at 0x9f3f0000 (maybe md will do that job). Most likely 2 groups of 6 bytes.

yea when i get back to my house tommaro ill post the output for md

just got over https://forum.openwrt.org/viewtopic.php?id=22311 (Netgear WNDR3700) and noticed that bootlog should start a bit earlier than you posted it here. Please check on that again, it seems to contain interesting infos on memorylayout. Also issuing printenv in uboot gives some neat infos.

ok, got some patches ready to hopefully get your wpn824n supported in trunk. i also ran a successful build, so now its up to you to test if it works. at best by just loading it into ram in u-boot and see how it goes. no warranty.
so, here is the patch:

good luck and have fun!

Grrr i think i pay have just blown the board -.- i dont get it.

You must be kidding me. After spending almost my whole weekend on that topic you just blow it?!?
So, anyway, how will you go on? Is this thread closed now?

[EDIT: initial version posted was missing the new file, mach-wpn824n.c - current version is correct]

I've taken these patches as a starting point and made a new set which is verified to work and builds a working trunk.  I've used the built in recovery mode to TFTP flash the factory-NA file and the router boots and runs apparently fully featured.  I may have missed some LEDs, and none of the buttons work yet, but for the most part it works great.

These apply to trunk r32760 as I just refreshed them now.  Actual patchfile available at http://www.freefilehosting.net/wpn824n-r32760_1 in case the codebox mangles tabs or something.

(Last edited by Spudz76 on 17 Jul 2012, 04:58)

OK I've tracked down the button GPIOs in the Netgear GPL 1.0.0.28 code, the issue is that all of them are connected to the AR9285.  I am having trouble figuring out if the ath9k driver even has an input/event layer in it (obviously it has output control, for LEDs, which works as seen above).  The original GPL code seems to build its own event polling loop (of course!) rather than maybe using the actual input events layer already in the kernel (why would anyone want that?).

Anyway, figured I'd report my findings in case anyone had some insight on how to get ath9k to register buttons (or if it's going to take some ath9k upstream work).

Spudz76: I'm attempting to reproduce your successful results with my own WPN824N. I got the r32760 code and patched it with your latest patch. I added
CONFIG_ATH79_MACH_WPN824N=y
to my configuration. Then I ran make, which completed successfully. My question is what file I am supposed to send to the router. The only ones with "factory-NA" in the filename are bin/ar71xx/openwrt-ar71xx-generic-wndr3700-jffs2-factory-NA.img and bin/ar71xx/openwrt-ar71xx-generic-wndr3700-squashfs-factory-NA.img. I would expect something more like bin/ar71xx/openwrt-ar71xx-generic-wpn824n-jffs2-factory-NA.img. Are these wndr3700 ones correct?

I am unsure why the wndr3700 ones got built, my trunk/.config has "CONFIG_TARGET_ar71xx_generic_WPN824N=y" and no other targets selected, however with the CONFIG_ATH79_MACH_WPN824N set in your kernel config (which would be set automatically by the above) the resulting kernel should work.  I have not tested jffs2 recently (and back when I did, it didn't work, but the MTD partitions were all goofed up still - now they are perfect) so you also should set "CONFIG_TARGET_ROOTFS_SQUASHFS=y" in your OpenWRT .config so that openwrt-ar71xx-generic-wpn824n-squashfs-factory-NA.img is built.  Then you need to trigger the recovery mode, one way is to intentionally brick the router during a reflash of the stock firmware (use the stock upgrade page to load the firmware, and then wait something like 15 seconds and cut the power, and then you should be stuck in recovery mode).  Or, you can open it up and use a level shifting console cable (same as any other 3.3v uart port on any other router) at 115200/8n1 the pin by the white square (pin 1) is Vcc, then the two data pins (not sure which is which but hey you have a 50/50 shot and nothing will fry if its backward), and pin 4 on the other end is ground.  Anyway once you have console going boot it up and you should see u-boot doing its thing, whack Ctrl-C before it actually loads a kernel and it will drop you to the prompt.  From there I usually use "fsload" which fails and ends up in recovery mode, but my original firmware is long gone (if you still have the stock image in flash, the fsload command may actually boot correctly instead of failing - I'm not sure as I bricked mine before OpenWRT was anywhere near it).  The router comes up at 192.168.1.1 by default, so follow the normal TFTP methods and send the squashfs wpn824n factory NA bin file and you will see the upgrade progress on the console.  It should take, flash, and reboot into fresh hot OpenWRT r32760.

I will come up with a much cleaner method but that should get you going.  I didn't spend much time figuring out the other commands in the u-boot that is on it.  You can use 'help' and there are plenty of commands to try, including nfs booting and a bunch of other stuff most stock router bootloaders don't have.  There is probably a direct tftp recovery mode command but the broken 'fsload' was the first thing I found that crashed it every time.

Just for fun, I uploaded my full trunk/.config file from which I build my test images - in case I forgot something else.  You should be able to diff it against yours to see where things may have gone wrong.  http://www.freefilehosting.net/openwrt- … n824n-luci

Oh, and my config above also has ipv6 and luci and a couple other things from feeds installed, so make sure your feeds are updated and installed if you want the useful bits to be there.

And after patching, and your tree is not fully clean, you need to at least remove trunk/tmp/.targetinfo so that it all gets reparsed when you run menuconfig, or the WPN824N won't show up.  To be safe you can whack the entire trunk/tmp directory and it will run through the prereqs and stuff too, just to be sure.

Your menuconfig target settings should look like this:

Target System (Atheros AR7xxx/AR9xxx)  --->
Subtarget (Generic)  --->
Target Profile (NETGEAR WPN824N)  --->

By removing the ./tmp directory and rerunning make menuconfig, I was able to get ./bin/ar71xx/openwrt-ar71xx-generic-wpn824n-squashfs-factory-NA.img to build.

I am able to get the router into recovery mode by sticking a pin into the hole in the back, powering the router on, and waiting for about 15 seconds. The lights start flashing, and then I'm able to transfer the image over TFTP. The router then appears to flash and reboot. Thus far, though, I seem to be unable to contact the router when it tries to boot off of this fimware.

Impossible to tell you what is wrong without some serial console output, unfortunately.  I don't think there are multiple revisions of this model, but perhaps there are slight differences.  I will attempt a flash on my remaining still-stock unit and see what happens then, maybe I can duplicate your failure.

I can tell you that it will come up far enough to respond to a few pings, but the replies are weird, truncated packets. So it replies to an ARP request and then receives and responds to the ping. I guess that's probably just the bootloader, though.

Yes, the corrupt replies are from the bootloader.
