Luke,

When you work with a WLAN package which uses tiwlan_drv.ko the ref clock as well as the irq are all taken for the ini file (tiwlan_drv.ini) in the file system and not from the platfrom data structure in the board file.

The platfrom data structure in the board file is used only when you work with nlcp.

Dear Luke,

Please let me know if you are using a custom built platform based on OMAP4 or Blaze/Panda (OMAP4 Refernce Platforms)?

For WiFi to work on L27.G.3 release on OMAP4 platform, the CONFIG_TIWLAN_SDIO flag is needed in kernel .config. Please check if this flag is enabled.

From the log - hPlatform_Wlan_Hardware_Init: timeout waiting for wifi device init – it seems that WiFi probe is failing and it may be due to WLAN_EN and WLAN_IRQ not set correctly. Please update the correct GPIO numbers based on your platform in kernel/arch/arm/mach-omap2/board-4430sdp-wifi.h and not in wl12xx_platform_data omap4_panda_wlan_data structure.

Please also verify that kernel/ arch/arm/mach-omap2/board-4430sdp-wifi.c is being used for compilation.

Please refer to http://www.omappedia.org/wiki/L27.G.3_OMAP4_GingerBread_Release_Notes for L27.G.3 WiFi build (Use make TNETW=1273 to build WiFi driver for WL1273 device).

Hello,

We have only tiwlan.ini file, not tiwlan_drv.ini

And there (tiwlan.ini) is no entries about irq nor enable pins, could you please tell us what we should add to this file to configure pin numbers ?

In platform data and in kernel/arch/arm/mach-omap2/board-4430sdp-wifi.h all pin numbers are set correctly

File kernel/arch/arm/mach-omap2/board-4430sdp-wifi is included in compilation

We still have problem with  drv->irq=0

Best regards,

Luke

Luke,

The tiwlan.ini doesn't have the information about the irq or WLAN_EN pins. That needs to be configured in kernel/arch/arm/mach-omap2/board-4430sdp-wifi.h which you mentioned as already done.

Can you please confirm if the CONFIG_TIWLAN_SDIO flag is defined in kernel .config. Please check if this flag is enabled.

Regards,

Naveen

Hi Naveen, 

I am working on http://omappedia.org/wiki/L27.G.5_OMAP4_GingerBread_Release_Notes on Panda ES, I am having issue with the wifi module. I am using the firmware provided in the http://omappedia.org/wiki/PandaBoard_L27.12.1-P2_Release_Notes#X-loader_Source 

The wifi module on the board is TiWi-BLE and building the source following way.

cd $MYDROID/hardware/ti/wlan/wl1283/platforms/os/linux
export KERNEL_DIR=${YOUR_PATH}/kernel/android-2.6.35
make ARCH=arm TNETW=1283 <HERE I USED 1273>

cd $MYDROID/hardware/ti/wlan/wl1283_softAP/platforms/os/linux
export KERNEL_DIR=${YOUR_PATH}/kernel/android-2.6.35
make ARCH=arm TNETW=1283 <HERE I USED 1273>

Issue:

When I go to settings and then turn wifi, it is showingin "turning On" and then after a couple of seconds showing "turning off" and it is never turning off.

What can be the reason for this issue.

Thanks.

Vamsi,

I would suggest you to refer to http://www.omappedia.org/wiki/PandaBoard_L27.12.1-P2_Release_Notes. There is a prebuilt binary package - http://www.omappedia.org/wiki/PandaBoard_L27.12.1-P2_Release_Notes#Prebuilt_binaries. Please try that first. This package (Gingerbread Pre-Built "DRAFT" Release Package) also contains kernel patches to enable BT and WiFi in Kernel for Panda board. I suspect that those changes might be missing in L27.G.5 release that you are using, so you need to apply/port those patches to L27.G.5.

Thanks,

Naveen

Hi Naveen, 

Wifi is working with  http://www.omappedia.org/wiki/PandaBoard_L27.12.1-P2_Release_Notes but it is giving the issue with this source http://omappedia.org/wiki/L27.G.5_OMAP4_GingerBread_Release_Notes. Presently i want make wifi work with the G.5 source.

Thanks.

Vamsi,

The default configuration for L27.G.5 release is Blaze board and for Panada board we need to make changes in GPIO (WLAN_ENABLE), MMC clocks etc. Those changes needs to be done in kernel of L27.G.5. For this please refer to this package - http://www.omappedia.org/wiki/PandaBoard_L27.12.1-P2_Release_Notes#Prebuilt_binaries. Specifically you need the changes from following patches.

0007-OMAP4-WLAN-Add-WLAN-PowerEnable-GPIO-for-Panda.pacth
0008-CONFIG_WIFI_CONTROL_FUNC-for-MACH_OMAP4_PANDA.patch
0011-arch-arm-mach-omap2-board-omap4panda.c-Disable-power.patch
0010-arch-arm-mach-omap2-hsmmc.c-Change-the-clock-speed-f.patch

Regards,

Naveen

Thanks Naveen, I will try and update you.

Hi Naveen, 

I have cross checked the patch, we have all these patches applied, like gpio settings and mmc pad muxing.

Thanks
