Forum Post: Wi-Fi: BlueGiga WF111 SDIO Driver for AM335x Problem

$

Hello!

In my custom board I have a BlueGiga WF111 chip connected to the MMC2 bus but I'm having a LOT of trouble trying to make its driver recognize the wireless card. So far nothing worked and I can't even get the driver to report that it found the card...

If anyone have ever worked with this driver, could you please help?

I would really like some guidelines on how to configure the struct omap2_hsmmc_info variable inside my board configuration file or anything related to the boot process and how to set the pins ready.

The first configuration I did was based on how the file board-am335xevm.c sets the WiFi for the wl12xx driver. The pins in my design match the ones the EVM uses, so I kept the pin mux configuration on my board file. It also configures a struct omap2_hsmmc_info variable (the on I previously mentioned) and I did the same thing, changing only what was necessary. Right now I don't know if I got this right.

With an oscilloscope, I see no response of any sort in the hardware when I load the driver, so maybe it is not finding the bus due to some configuration I got wrong...

What I'm trying to check is if I have everything right on the Kernel side of things. Their support is trying to help as well, but I need to be sure I'm not missing some simple configuration.

Any help will be greatly appreciated, even if it doesn't involve the WF111 driver directly. 

Thanks! 

DAVI
