TMS320F28379D: SPI-B not working

Part Number: TMS320F28379D


Hi, 

I have started working on tms320f28379D controller, using the development kit of texas instrument . I configured SPI-A, its working fine. I am getting data on the SPI pins  and also in the registers of spi-a in debug mode. In my project i need SPI-B also, so i configured it same as SPI-A(set all the spi-b registers same as spi-a). Now I am getting data in the spi-b registers in debug mode but not on the pins. I am not getting clock also. But while running it in loob back mode, I can see the data in the registers but not on the pins of SPI(checking it on oscilloscope). I am using GPIO pin 58, 59, 60 and 61, configuring it as SPI -b. Is there any other setting required for SPI-B, please guide me.
