MMC1 TI Wifi Card Problem

Hello Narasimman,

As you seem to be using custom hardware it is difficult to offer specific advice. Taking a look at the documentation for our WLink 8 Adaptor may help. The basic documents and Users Guide can be downloaded here:

http://zedboard.org/support/documentation/6491

There is a reference design here:

http://zedboard.org/support/design/6491/66

and there are several posts on our forum regarding bringing up our board combos, including these:

http://zedboard.org/content/steps-get-wlink-using-petalinux-microzed

Otherwise, since it is custom hardware, you might try posting your questions on one of the Xilinx Community Forums:

Hi Gary,

Thanks for replay,

I managed to get detecting the wlan interface, but i got new problem when i enable the interface using "ifconfig wlan0 up" command.

I don't know what is the issue, the irq are congured correctly.

I'm using MIO0 as wlan irq, and it's irq no. is 96...

Here is my device tree configuration...

wlcore {
    compatible = "wlcore";
    interrupt-parent = <&ps7_gpio_0>;
    irq = <96>;
    platform-quirks = <1>;
    board-ref-clock = <4>;
};

Can you suggest me, how to resolve this?

Regards,

Hello Narasimma,

I don't have anything to add to the comment above other than suggest the Xilinx Community forums again.
