So the core is configured with Frequency Ratio set to 2 and the AXI is configured to operate at 100 MHz). the ext_spi_clk is 80MHz.But I found no  sck signal  output.

I am using VIVADO 2017.2 on Windows7.

I have solved it.

I found that when configure Microblaze without check 'Use Instruction and Data Caches',it will work normally.

But I don't konw why.
