MSP430F5528: Problems with the SPI conif from the SLAA281B App Report (SPI communication with a SD Card)

Hi all,

I am trying to migrate the Code from the SLAA281B Application Report in my current project with the MSP430f5528.

But he config of the SPI connection doesn`t work. I connectet an oszi but there are no edges....

Thank you for your help!
