ar9170 : firmware not loaded

Hi,

I am trying to use the ar9170 driver with the netgear wn111v2, on an arm9 platform. I compiled the modules, and the driver loads fine:

Module                  Size  Used by

g_file_storage         21212  0
at91_udc               12696  1 g_file_storage

My issue is about the firmware, ar9170.fw. It is not found. I tried w/o luck 2 options:
1) loaded from user space under /lib/firmware
2) build the kernel 2.6.29 with ar9170.fw.

With option (1), the only thing I see under /sys/class/firmware is the pseudo file timeout, no filename for 60" (like I think it should).

Note that I have tried also an 802.11G adapter (iogear gwus23) with the very same issue. But in this case, the 'old' kernel I am using for arm9 (2.6.29) has support for this 802.11g adapter, and when I build it with 2.6.29 (therefore not using compat-wireless), I have no issue regarding loading the firmware (from user-space).

If anybody had any idea what I am doing wrong or missing, I would really appreciate it!

Regards,
Olivier

Hi,

compat-wireless does not use /sys/class/firmware but /sys/class/compat_firmware for firmware loading, because we had to backport the firmware loading part. In the udev directory is a udev rule and a script for firmware loading.
