Hi All,

 

We are porting the driver in Android 6 using SDIO interface Wi-Fi Card in MCIMX6Q-SDB Board.

By default kernel will be configured in BCMDHD_SDIO. if I use other SDIO Wi-Fi Card for porting, Card is not registering.  Always card getting removed.

 

If I use other SDIO Wi-Fi Card with BCMDHD_SDIO enable, I am getting below error :-

1) Any board configuration is there for SDIO Wi-Fi card interface?[We are using SD2 J500 port in MCIMX6Q-SDB Board]

2) How to disable BCMDHD_SDIO configuration in kernel ?.

3) After disabling the BCM Config, how to use other SDIO Wi-Fi Card?.

4) Else how to use Mutiple SDIO Wi-Fi Card?.

 

Last one week we are trying, the same error is continuously occurred. Please anyone help to fix above problem..

As we need to deliver this to our customer within a week.

 

Thanks,

Thanaraj.
