CCS/TDA3LA: SD card exchange problem

Part Number: TDA3LA

Tool/software: Code Composer Studio

Hello, everybody!

I have problem with SD card on my EVM development kit. 

I try to control the SD card, but card doesn't respond to any command.
Then I checked Card Detect pin (#9) and there weren't any changes. There is low signal on this pin when SD card is in slot. But there is the same state on this pin when card is out of slot.

I set I2C expander and checked all the SD lines on this slot with oscilloscope. But I can't find mistakes.

Is this a hardware mistake?
