kernel 2.6.24 USB wi fi device firmware loading issue(s): rt73.bin...
I received great help last week in getting a USB wi fi device working. Thanks again, but can someone read below and advise me on kernel 2.6.24? The best out-of-the box solution for me was 2.6.27.8, for which I needed a Denx eldx toolchain in place of the toolchain I was using to compile 2.6.24. The significance of all this is that I did get USB wi fi working, but... I'm not in a position to upgrade from 2.6.24 at this time. I need to get the USB wi wi (Linksys WUSB54GC) working under 2.6.24. After success with linking firmware with the 2.6.27.8 kernel, 2.6.24 I keep hitting this error when loading from user space (I don't appear to have the, link with kernel option with 2.6.24)... sh-2.05b# ifconfig wlan0 up [ 764.744354] phy0 - rt2x00lib_request_firmware: Info - Loading firmware file 'rt73.bin'. After a considerable delay I get an error that indicates the file can't be found. I have spent many, many hours following leads (and links) this group has directed me to. Thanks again. I'm either missing a very simple step or indeed support under 6.2.24 is not good. Please advise. I've done the following... 1)placed rt73.bin in various locations (/lib/firmware, lib/firmware/'uname -a', and the location specified by my /etc/hotplug/firmware.agent), according to tips on some threads I've read. None of this appears to make a difference. 2) I'm a bit confused by the hotplug dependancy, although I do have hotplug enabled. hotplug makes me think I should be configuring some script to load the firmware upon device insertion, but, ifconfig wlan0 up appears to want to load the firmware anyway so I'm guessing if I just get rt73.bin installed correctly it should work. Comparing my working 2.6.27.8 to 2.6.24 in the areas of, firmware and the ralink rt2x00 drivers reveals MANY changes, no doubt for the better. QUESTIONS: 1) Am I missing something VERY simple on this firmware loading topic that should make this work under 2.6.24, or am I bumping into the reason so much of this code has changed between 2.6.24 and 2.6.27.8? -linking firmware with the lernel at compile time is a nice, obvious method offered by the later kernel. I'm confused by the userspace method and I think this is where my problem lay. 2) am I correctly, installing the firmware just by placing rt73.bin in the correct location in my filesystem, or is there some other magic required before, request_firmware() will work? Just when I thought I understood some of the kernel I hit a new topic: firmware loading!

kernel 2.6.24 USB wlan firmware loading issue(s): rt73.bin...
I received great help last week in getting a USB wi fi device working.
Thanks again, but can someone read below and advise me on kernel 2.6.24?
The best out-of-the box solution for me was 2.6.27.8, for which I needed
a Denx eldx toolchain in place of the toolchain I was using to compile
2.6.24. The significance of all this is that I did get USB wi fi
working, but...
I'm not in a position to upgrade from 2.6.24 at this time. I need to get
the USB wi wi (Linksys WUSB54GC) working under 2.6.24.
After success with linking firmware with the 2.6.27.8 kernel, 2.6.24 I
keep hitting this error when loading from user space (I don't appear to
have the, link with kernel option with 2.6.24)...
sh-2.05b# ifconfig wlan0 up
[ 764.744354] phy0 - rt2x00lib_request_firmware: Info - Loading
firmware file 'rt73.bin'.
I have spent many, many hours following leads (and links) this group has
directed me to. I've done the following...
1)placed rt73.bin in various locations (/lib/firmware,
lib/firmware/'uname -a', and the location specified by my
/etc/hotplug/firmware.agent)
None of this appears to make a difference.
2) I'm a bit confused by the hotplug dependancy, although I do have
hotplug enabled. hotplug makes me think I should be configuring some
script to load the firmware upon device insertion, but, ifconfig wlan0
up appears to want to load the firmware anyway so I'm guessing if I
just get rt73.bin in the right spot it should work.
Comparing my working 2.6.27.8 to 2.6.24 in the areas of firmware: and
the ralink rt2x00 drivers reveals MANY changes, no doubt for the better.
QUESTIONS:
1) Am I missing something VERY simple on this firmware loading topic
that should make this work under 2.6.24, or am I bumping into the reason
so much of this code has changed between 2.6.24 and 2.6.27.8?
2) am I correctly, installing the firmware just by placing rt73.bin in
the correct location in my filesystem, or is there some other magic
required before, request_firmware() will work?
Just when I thought I understood some of the kernel I hit a new topic:
firmware loading! Any help much appreciated...

Kconfig presents options slightly different from what you describe
below. I've tried a few different settings and I placed the rt73.bin
you sent me under /lib/firmware.
I'm still getting the failure to load rt73.bin error on ifconfig
wlan0 up.
my generic Kconfig options read as follows. I'm not sure if/what
option maps to, include in-kernel firmware blobs in kernel binary
Could this be a udev issue?

? ? [*] Select only drivers that don't need compile-time external
firmware
? ? [ ] Prevent firmware from being built
? ? {*} Userspace firmware loading support
? ? [ ] Driver Core verbose debug messages
? ? [ ] Managed device resources verbose debug messages
I'll keep trying different things, but if you can provide additional
guidance I will appreciate it very much. Thanks again.

Re: toolchain for building linux-2.6.27.8 or 2.6.28.1 AND USB wi fi SUCCESS...
Thank You! I obtained ELDK 4.1 from Denx and built 2.6.27.8 with it. A couple host tool links were required but the build was pretty painless. Ultimate goal I startedon early in the week was USB wi fi using the Linksys WUSB54GC, which requires the ralink rt73 driver. The 2.6.27.8 menuconfig offered the firmware loading options I was looking for. I now have a working USB wi fi device.

Mike: Denx's ELDK 4.1 or 4.2 make a great It Just Works solution. I've used 4.1 running from 2.6.23 up to 2.6.27.11 and 4.2 from 2.6.26 to 2.6.27.11 with zero problems or issues.

toolchain for building linux-2.6.27.8 or 2.6.28.1 ...
I wrote a couple days ago needing advice on USB wi fi. I made some progress but then I hit a snag loading the USB wi fi adapter firmware. Jon schooled me on the firmware topic (thanks Jon), and advised me to select the following Kconfig options Kconfig Device drivers generic driver options user space firmware support check - include in-kernel firmware blobs in kernel binary My 2.6.24 kernel didn't offer these options, and I also suspected that since 2.6.24 some progress on the ralink drivers I need has been made I figured I'd just try a new kernel build and try to get my ralink-equipped Linksys WUSB54GC to work. Trouble: -I was using Ltib Toolchain (gcc-3.4.3-glibc-2.3.6 (for 603e)) to build my 2.6.24 kernel. -It looks like somewhere after 2.6.24 this toolchain stopped successfully compiling the kernel. So, -I used crosstool and built 4.1.0 and 4.1.1 toolchains. Both produce the following error: OBJCOPY arch/powerpc/kernel/vdso32/vdso32.so objcopy: Unable to recognise the format of the input file `arch/powerpc/kernel/vdso32/vdso32.so.dbg' make[3]: *** [arch/powerpc/kernel/vdso32/vdso32.so] Error 1 make[2]: *** [arch/powerpc/kernel/vdso32] Error 2 Questions: 1) if I want to cross-compile a kernel later than 2.6.24 to hopefully get better WAN device support (and clearer options for fw loading), which kernel should I try, and which toolchain? the ltib repository does not appear to have a toolchain newer than gcc-3.4.3-glibc-2.3.6 (for 603e) Admissions, disclaimers, etc 1) I'm using the same ltib script I have used for the 2.6.24 build with toolchain gcc-3.4.3-glibc-2.3.6 (for 603e).

If you are looking for a suitable wifi adapter, then that device
should work, but if you can go with a PCI or a miniPCI WiFi adapter
instead then you should get better performance. The 5200 only has USB
1.1.
I'm having good success with an Atheros miniPCI adapter at the moment
using a 2.6.28 kernel.
