[ath9k-devel] insmod ath9k error

[bing_chou <bing_chou@bandrich.com>]

Hi all

 

I got a error when insmod ath9k.ko and the ?art block? is null that it
will show ?data bus error? below 

root at OpenWrt:/# insmod ath9k

[  143.200000] Data bus error, epc == 83b83ed8, ra == 83b83ed8

[  143.200000] Oops[#1]:

I think it is caused by opt address , and then I modify the file of
build_dir/linux-ar71xx_generic/compat-wireless-2012-09-07/drivers/net/wirele
ss/ath/ath9k/ar9003_eeprom.h

From 

Line 71 : #define AR9300_OTP_BASE 0x14000

Line 72 : #define AR9300_OTP_STATUS 0x15f18

Line 77 : #define AR9300_OTP_READ_DATA 0x15f1c

To 

#define AR9300_OTP_BASE                   (AR_SREV_9340(ah) ? 0x30000 :
0x14000) 

#define AR9300_OTP_STATUS                (AR_SREV_9340(ah) ? 0x30018 :
0x15f18) 

#define AR9300_OTP_READ_DATA                (AR_SREV_9340(ah) ? 0x3001c :
0x15f1c) 

 

But it still shows the error message below

[   12.320000] ath: phy0: Unable to initialize hardware; initialization
status: -5

[   12.320000] ath9k ar934x_wmac: failed to initialize device

[   12.330000] ath9k: probe of ar934x_wmac failed with error -5

 

Could someone please tell me how to fixed?

 

Thanks
