Enabling wifi driver

ArifKhan — Tue, 31 Jan 2012 09:14:53 GMT

Hi, I am working on SABRE TABLET board, I am able to bring up the board and boot from the SD card, I compiled the wifi driver as Module and loaded the module as below root@freescale ~$ cd /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net/wireless/<.35.3-998-ga1cd8a7/kernel/net/wireless/cfg80211.ko root@freescale ~$ cd /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net/wireless/kernel/net/ root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net$ ls wireless root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net$ cd wireless/ root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net/wireless$ ls cfg80211.ko root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net/wireless$ modpro</2.6.35.3-998-ga1cd8a7/kernel/net/wireless$ modprobe cfg80211.ko cfg80211: Calling CRDA to update world regulatory domain root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net/wireless$ root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net/wireless$ root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/net/wireless$ cd ../</2.6.35.3-998-ga1cd8a7/kernel/net/wireless$ cd ../../drivers/net/wireless/ <35.3-998-ga1cd8a7/kernel/drivers/net/wireless/ath$ modprobe ath.ko <35.3-998-ga1cd8a7/kernel/drivers/net/wireless/ath$ <35.3-998-ga1cd8a7/kernel/drivers/net/wireless/ath$ <35.3-998-ga1cd8a7/kernel/drivers/net/wireless/ath$ cd ../../../staging/ root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/drivers/staging$ ls ath6kl root@freescale /lib/modules/2.6.35.3-998-ga1cd8a7/kernel/drivers/staging$ cd </2.6.35.3-998-ga1cd8a7/kernel/drivers/staging$ cd ath6kl/ <6.35.3-998-ga1cd8a7/kernel/drivers/staging/ath6kl$ ls ath6kl.ko <6.35.3-998-ga1cd8a7/kernel/drivers/staging/ath6kl$ modprobe ath6kl.ko ath6kl: module is from the staging directory, the quality is unknown, you have been warned. <6.35.3-998-ga1cd8a7/kernel/drivers/staging/ath6kl$ AR6000: Unsupported configuration opcode: 3 AR6000: Unsupported configuration opcode: 3 HIF Interrupt processing is SYNC ONLY AR6000: Unsupported configuration opcode: 7 AR6000: Unsupported configuration opcode: 5 In aggr_init.. going out of aggr_init..status OK Unknown firmware revision: 805307778 ar6000_avail: ar6000_sysfs_bmi_get_config failed <6.35.3-998-ga1cd8a7/kernel/drivers/staging/ath6kl$ <6.35.3-998-ga1cd8a7/kernel/drivers/staging/ath6kl$ <6.35.3-998-ga1cd8a7/kernel/drivers/staging/ath6kl$ /etc/rc.d/init.d/network restart Running sysctl Setting up networking on loopback device: Warning: no IPADDR is set, please set this from the ltib config screen, or directly in /etc/rc.d/rc.conf.

Has anyone tried building the wifi driver, I am using L2.6.35_11.05.01_ER_source bsp package.

Re: Enabling wifi driver

Kirill — Wed, 14 Mar 2012 11:10:26 GMT

I have the same message, did you solve it?

Re: Enabling wifi driver

ArifKhan — Wed, 14 Mar 2012 12:53:20 GMT

Hi Kirill, Driver availabe with L2.6.35_11.05.01_ER_source bsp package is of wifi chip with h/w rev 2.0, whereas chip in tablet is of 2.2.1 version. I used another bsp L2.6.35_11.09.01_ER_source, which has latest driver given as separate package rather than part of kernel, I suggest you to use this latest bsp as it has all patch update. you can download bsp from here http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX53QSB&fpsp=1&tab=Design_Tools_Tab Regards Arif

Kirill — Wed, 14 Mar 2012 12:58:03 GMT

Did you get it worked?

Re: Enabling wifi driver

ArifKhan — Wed, 14 Mar 2012 13:27:53 GMT

yes its working for me ... atheros-wifi-11.09.01.tar

Re: Enabling wifi driver

Kirill — Wed, 14 Mar 2012 13:36:08 GMT

Thanks Arif for replies! You worked with SABRE's build-in Atheros AR6003? And I did not recognize your last post line "atheros-wifi-11.09.01.tar"

Re: Enabling wifi driver

ArifKhan — Wed, 14 Mar 2012 13:52:53 GMT

atheros-wifi-11.09.01.tar is the package name available in L2.6.35_11.09.01_ER_source bsp wich worked for me. this is not a built in driver and u need to compile it separately and have to used ar6000.ko module generated after compile. I din used builtin driver AR6003.

Re: Enabling wifi driver

Kirill — Wed, 14 Mar 2012 14:09:12 GMT

I meant buildin chip. And one more question, you launch driver insmod ar6000.ko and you got wlan interface or you launch some Atheros's scripts?

Re: Enabling wifi driver

ArifKhan — Thu, 15 Mar 2012 06:01:26 GMT

yes Kirill, its built in chip.I din used any atheros script, just insmod ar6000.ko and got eth1 enterface.

JackyHuang — Mon, 21 May 2012 09:40:10 GMT

hi Arif

I follow your comment to build the ar6000.ko, but after I insmod the ar6000.ko , I can't get the eth1 by ifconfig

Is there any configuration about the wireless in the kernel?

Thanks advance
