Anybody get the 520gU wireless (B43) to work with 2.6 kernel

Anybody get the 520gU wireless (B43) to work with 2.6 kernel

Post by displacedtexan »

So, great project!

Not only is the project great, but it is complicated enough that I would not have been able to do it on my own...

Now my question... I was hoping to use a webcam with a 520gU, but that will require a 2.6 kernel.

According to OpenWRTs webpage, the opensource B43 drivers should be in a more use-able state now:

Code: Select all

Backfire 10.03 Beta

*** BETA RELEASE ***
The OpenWrt Team would like to announce a beta of the next major release, codenamed Backfire. Testing of this build will help refine the code in preparation of the final release.

Binaries can be downloaded at http://downloads.openwrt.org/backfire/10.03-beta/

Highlights:
* brcm-2.4 updated to 2.4.37 kernel
* other targets updated to 2.6.30 or 2.6.32
* gcc updated to 4.3.3 for arm/mips targets, 4.4.3 for powerpc
* uClibc updated to 0.9.30.1
* b43 wireless driver for Broadcom 11g chipsets on the 2.6 kernel
* ath9k wireless driver for Atheros 11n chipsets
* support for many new ar71xx devices
* magicbox target folded into ppc40x

new targets:
* brcm63xx - Broadcom ADSL modem/routers chipset
* cobalt - MIPS-based servers from Cobalt Networks
* orion - Marvell Orion devices

Known Issues:
* ipv6 resolution via uClibc can produce segfaults
* busybox httpd occaisionally segfaults or hangs, but luci uses lucid instead of httpd by default. kill -9 should be used if it refuses to die
* luci is still being worked on for this release, some configuration is missing, partiuclarly switch config and 802.11n options

[b]Note: We said we'd tell you when brcm47xx should work for those of you with Broadcom wireless, the time is now, start testing.[/b]
I can't get wireless to associate with thee new Backfire release.

Anybody else been successful?

I would have posted this on the openwrt forums, but there registration process is broken with the following errors:

Code: Select all

Again thanks for everyone's help!

I have not had a chance to play with the B43 drivers in 2.6 since my initial experiments in 2008. Let us know if you get it working!

I would like to use 2.6 kernel for better usb support and lirc ;)

displacedtexan, I have been trying to do exactly the same thing as you for months on my WL520-GU . I want to connect a webcam to it and use mjpg-streamer. I can get wireless working fine on the 2.4 kernel, but mjpg-streamer requires 2.6. I can get wifi OR mjpg-streamer, but not both together -- which is what I want.

As soon as I turn wireless on on my WL520-GU, it stops responding. Initially, this required me to re-flash every time it crashed. VERY annoying. So, I built scripts to automatically flip back to working config files every reboot. This way at least I don't have to re-flash every time it crashes -- I just reboot and it's back to a working configuration with wireless turned off. This has also allowed me to more easily tweak the configuration without starting from scratch each time.

However, I have had no success with anything up to and including Backfire 10.03-rc3 . I hope this gets fixed soon.

I got Backfire 10.03 (latest release) working on my Asus WL-600G, Asus WL-500GD, Linksys WRT54G, and WRT54GL, including wireless in both AP and STA mode with WPA2

However, on my Asus WL-520GU the b43 driver says "microcode not responding" and refers to the wireless website for getting better firmware. The WiFi chip is a Broadcom 5354, for which http://wireless.kernel.org/en/users/Dri ... chip_types says "Supported?". It looks like the 520GU still needs some tweaking

Finally got my Asus WL-520GU working with Linux 2.6 AND wireless, using Backfire 10.03 brcm47xx

Be sure to select CONFIG_B43_STABLE and *NOT* CONFIG_B43_EXPERIMENTAL, the WL-520GU needs the 4.150.10.5 firmware. I also updated to the very latest compat-wireless driver package

FYI Here's my setup and installed packages, unfortunately 'mpd' doesn't seem to fit in the 4MB flash with the 2.6 kernel (at least not without some stripping,TBD):

Re: Anybody get the 520gU wireless (B43) to work with 2.6 ke

jbemmel: Could you post your .config file and any other customizations you applied? I'm using the same HW and backfire (building from backfire branch on svn), but turning on the wireless is still locking up my box and I want to compare builds.

thanks!

Grab the latest firmware from the snapshots folder. The wireless problems were fixed after 'backfire' was released.
Been quite stable for me so far.
