Kernel config to enable option for wireless
« on: April 27, 2011, 10:57:59 PM »
Hi all,

I'm trying to configure my USB wireless which is supported in linux for my laptop, but it requires these options to be enable in the kernel config.

http://linuxwireless.org/en/users/Drivers/ath9k_htc

CONFIG_ATH_COMMON=m
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K_HTC=m

My question is how do I go about enabling this in TC? Is there a post that someone can refer me to, as I have used the search for this topic with no luck.

Thanks for your time.

According to
http://distro.ibiblio.org/tinycorelinux/3.x/release/src/kernel/config-2.6.33.3-tinycore
those are already set, except from the last one; perhaps that option did not yet exist in 2.6.33?

From a search here:
http://kernel.xc.net/
it looks like latter was introduced in 2.6.35.
Perhaps you could look into compat-wireless.

Thanks Arslan & tinypoodle for your reply

I have used the compat-wireless extension, mkdir a /lib/firmware and used a the new and old firmware but I'm still getting the "Firmware - ar9271.fw not found". The following dmesg output below.

I was wondering if I need to load it at boot much like for wicd-start?

I've found that wireless firmware needs to be loaded before the corresponding wireless module is loaded.

If you made an extension out of your firmware, I'd recommend to make sure it is loaded before the compat-wireless extension.

You can test the theory by copying the relevant extensions to /tmp without any *dep files and loading them one by one with "tce-load -i /tmp/extension_name"

Thanks Juanito for your reply.

The firmware is only a single file which was place into /lib/firmware, I have removed compat-wireless extension and rebooted the laptop and then once back in again, I reload the compat-wireless exention but with not luck in detection. Still saying "Firmware - ar9271.fw not found", and couldn't find info on compat-wireless usage.

what else can I do to resolve this anyone?

thanks for your time

@TroyB: Well, I can't help myself but this sounds an awful lot similar to this thread. In all the cases where my WiFi devices (both built-in as well as USB stick) require a firmware file it won't be required until one activates the device (e.g. with 'ipconfig DEV up'), but I can imagine that other devices require such a file already at the loading of the kernel module (i.e. the installation of the 'wireless-KERNEL.tcz' or 'compat-wireless-KERNEL.tcz' extension).

Instead of installing the whole 'firmware.tcz' extension I'm only using a few commands that are creating the '/usr/local/lib/firmware' directory and are copying the few files that any one of my WiFi devices might require into that directory. All this happens before the kernel modules are loaded and the device is activated. Instead of doing is this way I could have also done it via backup or a private extension. In the end it does not matter how the files are getting in the right place but as Juanito wrote in reply #5 the timing is critical.

In any case I can only repeat what I've written in the other thread: to troubleshoot such an issue do things really slowly step-by-step (e.g. only put relevant extensions into 'onboot.lst' after all problems have been sorted out and dependencies are clear). Maybe also worth following the advice from Arslan as of reply #12 of the other thread to get a potentially updated version of the file in question.

no difference in usage to in-kernel wireless modules   ;)
