Marvell SD8787 with linux-imx

Hello,

 

i'm trying to interface a Marvell SD8787 wlan module with an i.MX6Q SoM from Karo Electronics. Therefore i am using the Freescale Community Bsp (Krogoth Branch). I've build an Image based on the linux-karo_4.1.15.bb recipe and followed the steps to configure the driver, described here: Marvell 8787 based wifi module using SDIO

 

But the kernel does not recognize the module after the driver was loaded (modprobe mwifiex_sdio). 

There is no entry like: 

mmc1: new high speed SDIO card at address 0001

It seems like the module doesn't even start.

It works perfect with an older kernel (3.0.35) on the same board, but i need to change to the newer kernel.

 

What could possibly gone wrong or missing?
