AM1808 + Micro SDcard

Hi,

I have interfaced AM1808 MMCSD0 to micro sdcard, below are the pin configuration.

SD_CLK --> MMCSD0_CLK

SD_CMD --> MMCSD0_CMD

SD_DATA0 --> MMCSD0_DAT[0]

SD_DATA1 --> MMCSD0_DAT[1]

SD_DATA2 --> MMCSD0_DAT[2]

SD_DATA3 --> MMCSD0_DAT[3]

There is no card detect and write protect pin... When i boot the kernel no mmc blocks are detected. What changes in the kernel i need to do for card detection.

Kernel version : 

root@am180x-evm:~# uname -a
Linux am180x-evm 2.6.33-rc4 #9 PREEMPT Tue Sep 27 11:02:26 IST 2016 armv5tejl GNU/Linux

Thanks and Regards,

Dileep
