Linux/AM3358: SD card Detection GPIO Pin problem

Part Number:AM3358

Tool/software: Linux

Hi,

I am recently working AM3358 base custom board and custom Linux SDK.

I have followed all the process to create Linux SDK image from the prebuilt image as mention this web:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview_Getting_Started_Guide.html#linux-sd-card-creation-guide

But I m facing problem in booting process as it's not detecting SD card. I got to know after reading many threads that there is detect GPIO pin for SD detection (in my case :SPI0_CS1(GPIO_6)).

When I make that pin low manually in my custom board, its detect SD card and start booting and everything will work fine.

So How do I Configure that pin so it detects SD card directly?

I know there is some configuration need to do that ignore detection process and start directly.

please help me out.

Thanks in advance
