Wl12xx

[Dileep D R]

Hi,

Interfacing wifi module (wl12xx ti chipset) with beaglebone black. Unable to bring up wlan0 interface, please guide me for proper device tree configuration.

After booting excecuted
modprobe wlcore_sdio
modprobe wl12xx


Below are my configurations.

I don't see a wl12 boot message when the firmware is successfully loaded

[Dileep]

Wl12xx will not support device tree. Need to find out other procedure to enable in some board init function

why not? this package enables wl12 for TI's am335x EVMSK and uses the device tree

http://www.ti.com/tool/PROCESSOR-SDK-AM335X

[drhun...@gmail.com]

Hi,
Which wilink device are you building for?
The wl18xx family is now fully supported in 4.1 kernel. There is a device tree file for the wl1835 cape in the kernel that is best place to look.
If you are looking at wl127x or wl128x then device tree will be similar but you'll need to build the Wi-Fi drivers out of tree.
For the wl1835 cape look at the ti processor wiki for a page to describe full build and configuration on 4.1 kernel.
Iain

[Iain Hunter]

Hi,
As a follow up I agree with the previous statement that wl127x drivers have no device tree support. So you'll need to merge device tree support from wl18xx drivers. As far as I can remember there are no major changes to parameters passed by device tree to WiFi driver from wl127x to wl18xx. As long as you successfully pass the wl12xx probe function without an error you should be ok. Caveat is that I've not done this exercise.
Iain

[Dileep]

Hi,
 

When i add wl12xx module, none of the functions from wl12xx and wlcore are getting called.

Did you use device tree in the end or modify a board.c?

If so that looks like the mmc port is not being probed correctly as it is not defined. You should at least get some activity on mmc to try and read the type of "sd card" on this bus. This should identify as a wl12xx and then load the drivers when you insmod wlcore_sdio

Hi lain,

I have configured MMC3 for SDIO communiction. but still sdio communication is not up.

If clock is not enabled by default for MMC3 how can it be done in device tree,

dmesg log shows:

Hi

This is not good. You have tried to start mmc3 but it failed to get a regulator, so may not have continued its initialisation - i don't know how driver behaves in this case.

 omap_hsmmc 47810000.mmc: unable to get vmmc regulator -517

So suggestion would be to trace omap_hsmmc driver to understand why it fails to get a regulator.

Hi  Dileep,

I am also trying to bring up wl12xx based on BBB kernel. Is there any update on this ?

Do we need to use &mmc2 or & mmc3 ?  

Thanks & Regard

Raghu Ramaraj

Hi Raghu,

you should use &mmc3.

Because of other work, currently we are not working on that. still we need to debug SDIO communication on hardware line.

Regards,

Dileep
