SDSPI_open failed

Hello, I'm using TI-RTOS in F28M35H52C1

I create a task and fill with this code

SDSPI_Handle sdspiHandle;
	SDSPI_Params sdspiParams;

	/* Mount and register the SD Card */
	SDSPI_Params_init(&sdspiParams);
	sdspiHandle = SDSPI_open(0, 0, &sdspiParams);

But after SDSPI_open the Handle is NULL

 

can someone help me?
