Zynq on a custom board cannot read BOOT.bin file in SD card



I am working with a custom board with a Zynq7100. When I tried to start a helloworld project from SD card, the information returned from the uart is the following:


Xilinx First Stage Boot Loader 
Release 2017.1  Jul 12 2017-20:45:14
Devcfg driver initialized 
Silicon Version 3.1
Boot mode is SD
SD: rc= 0

I have already read the other problems on the forum, but what is different in my work is : there is no error message output like "SD init failed" or others. The boot procedure stuck in the "f_open" function and no longer proceed. I have tried the method like modifying the frequency of SD card in vivado or in SDK code, but none of them worked.
