wifi can't work on ICS

Are you sure you have the module inside /system/lib/module?

You should have something like:

ll /system/lib/modules/                                  
-rw-r--r-- root     root      2975542 2012-05-24 17:51 cfg80211.ko

-rw-r--r-- root     root       270082 2012-05-24 17:51 wl12xx_sdio.ko

check in kernel log if there is something about wl12xx module

Hi ICe,

I have all the required modules in /system/lib/modules:

$ ll /system/lib/modules

-rw-r--r-- root     root      2969838 2012-06-02 00:46 cfg80211.ko

-rw-r--r-- root     root       536010 2012-06-02 00:46 compat.ko

-rw-r--r-- root     root       300688 2012-06-01 06:02 pvrsrvkm_sgx544_112.ko

-rw-r--r-- root     root      2731020 2012-06-02 00:46 wl12xx.ko

-rw-r--r-- root     root       269883 2012-06-02 00:46 wl12xx_sdio.ko

I porting the WIFI followed TI-Android-ICS-PortingGuide.pdf step by step. The kernel log is:

2477.kernel_log.log

On our custom board, the only difference is that there are other two GPIOs should be enabled before GPIO_WIFI_PMENA. I enable them in function fixed_voltage_enable() of fixed.c, did I enable them in the right place?

Best Regards!

Hi Jow,

Are you installing the modules in your init.omap4platform.rc file?, you should see the module is loaded in your booting log.

Hi ICe,

The modules have been installed, as following:

$ lsmod

wl12xx 166793 0 - Live 0xbf0f1000

mac80211 322997 1 wl12xx, Live 0xbf08e000

cfg80211 177902 2 wl12xx,mac80211, Live 0xbf056000

omaplfb_sgx540_120 16997 0 - Live 0xbf04e000

compat 2814 0 - Live 0xbf04a000

pvrsrvkm_sgx540_120 258314 39 omaplfb_sgx540_120, Live 0xbf000000

But I think the wl12xx.ko has not been installed successful, because the wl12xx_probe is not been called.

And when I click wifi enable button from the UI, wl12xx_sdio.ko could be inserted into the kernel, but the wl1271_probe was not been called too.

1、I supposed that the wifi module does not be powered on. As I said earlier that there are other two GPIOs should be enabled before the GPIO_FIFI_PMENA.

2、In file wl12xx/mian.c, there is a platform_driver named wl12xx_driver, but I don't find a platform_device which named wl12xx_driver. Will this lead to wl12xx_probe not to be executed?

Regards!
