Hi,
When I looked at the SPI lines using the oscilloscope, I saw that the MISO line had the same signal as the MOSI line. As you can see from the image, basically SPI configuration works properly. Before message transfer CS pin goes low, and after that, the MOSI line works. I can read message that I sent using the oscilloscope.
What can be the problem with the MISO line signal reflecting the MOSI line signal? The SPI config stage CPOL = 0, CPAH = 1, I am using a 2 MHz clock signal. Thanks for your help.
