spi master hao no output signal

[wen]

I use the spi_master_example,but the mosi have no output signal(from the oscilloscope).Why?

[Sigurd]

I just tested the example, and I see a signal on the MOSI. The MISO signal on the other hand is always low, as expected.

Thanks,I found the error,it's my fault.
