Hello guys,


I am Felipe López and I am working with an TL-WN722N that comes with a
AR9271 chipset. I got it to work in my PC some time ago but now I am
trying to install it in a ARM CPU.

I selected the driver I need (./scripts/driver-select ath9k) and I
cross-compiled it against the kernel 2.6.30. I think that everything
is OK up to here. I get the following *.ko files:

./drivers/net/wireless/ath/
ath.ko
./drivers/net/wireless/ath/ath9k/ath9k.ko
./drivers/net/wireless/ath/ath9k/ath9k_common.ko
./drivers/net/wireless/ath/ath9k/ath9k_htc.ko
./drivers/net/wireless/ath/ath9k/ath9k_hw.ko
./net/mac80211/mac80211.ko
./net/rfkill/rfkill_backport.ko
./net/wireless/cfg80211.ko
./compat/sch_codel.ko
./compat/sch_fq_codel.ko
./compat/compat.ko
./compat/compat_firmware_class.ko

The first thing I do not know is in which order I should do the
insmod. I suppose that compat.ko should be the first but then comes
the second problem. This is what the board throws when I do the insmod
of compat.ko:

compat: Unknown symbol cpufreq_cpu_put


I googled for that sentence and I found that that function is used in
kernels >= 2.6.31 so maybe I should use an older version of
compat-wireless. What version of compat-wireless is the best for the
kernel 2.6.30? The only I can imagine I can solve the last problem by
myself is trial-error.


Many thanks in advance
