Hi,

I am trying to get Murata 1DX EVK to work on my QWKS-SCMIMX6 board rev 2.

The connection done via SDcard slot and Murata version2 adapter, with jumper at 3v3 position.

Kernel version: 3.14.52

I've compiled BCMDHD driver as a module and installed Broadcom firmware package for i.MX Linux L3.14.52 BSP.

In Uboot I've selected the imx6dqscm-1gb-qwks-rev2-wifi-fix-ldo.dtb as and fdt_file.

When I try to load the bcmdhd module i get the following output:

dhd_module_init in

Power up adapter 'DHD generic adapter'

wifi_platform_bus_enumerate device present 1

failed to power up DHD generic adapter... 3 retries left

wifi_platform_bus_enumerate device present 0

wifi_platform_bus_enumerate device present 1

failed to power up DHD generic adapter... 2 retries left

.

.

.

When I try the same without the murata EVK being connected, I get the same result.

The same SD card slot works great when a standard 8GB SDcard is inserted.

A brief look at the DTB shows that there is no CD(card detect) pin referenced. Maybe here is the problem?

Did someone succeeded at getting murata 1DX to work on QWKS-SCMIMX6rev2 board?

What can I do to solve the problem?

Thanks
