Hi All,
We have a 3.12 Linux Kernel running on a DM368 board with a WL1273L wifi module connected through the SDIO. We've been successfull at using the wifi when the SDIO is setup as PIO. However, when we enable DMA support in the kernel, the wifi stops working.
All the wifi modules are loaded correctly, however the wlcore.ko module halts when we perform an "ifconfig wlan0 up" on wlcore_boot_static_data function from wlcore module.
Any ideas?
Thanks in advance
Booting without DMA support, Wifi modules are loaded after boot with a user script.

Thanks
Joan,
A number of us on this board have been unsuccessful getting wl12xx working with linux 3.12 - would you mind sharing how you were able to get it up and running? Specifically which drivers you used and what your device tree config looks like? Any pointers would be much appreciated!
Thanks,
Chris
Hi Chris,
I'm not using a device tree. I just cloned the latest kernel following the website steps, generate a filesystem and cross compile the tools following the instructions here:
http://wireless.kernel.org/en/users/Drivers/wl12xx
http://wiki.beyondlogic.org/index.php?title=Cross_Compiling_iw_wpa_supplicant_hostapd_rfkill_for_ARM
You can see the modules I load in the error below.
However, I still have some problems.
The Access Point (hostapd) shows in client devices when scanning, however when I try to connect from any client. the access point disappears.
Also, when I do a "ifconfig wlan0 down" I get the following error:

I have used several firmwares without success.
My current feeling is that not all the interrupts are being received properly. Because I get also a watchdog timeout when working in client mode.
Thanks
