I would like to connect SPI IP core of microblaze on custom board but I have some problem. I need 100-400 KHZ clock but the system clk is 100MHz and SPI Clock is 6.25 MHz. Is it necessary to reduce clk frequency for initialization?
I just send CMD0 to reset,I would like to check the write and read buffer to see tranfering of command is correct,but I couldn't get a correct result.
IS anybody can help me ?
