[W5500 SPI Issue] No Response On MISO

Hi all,
I am working on MCU conmmunicate with W5500. There is a problem that It doesn’t respond to anything no matter what command I send.
Anyone can help me? thanks.

I try to set BaudRate 50M/8M or others, It’s no working. Problem is still exists

You can see that MISO responds to the command with 0x01, 0x02, and 0x03, thus SPI communication works properly. Simply the data being accessed (what SPI command is used?) is all zeros.

all of register return 0x00,

Why do you think they must return non-zero values? Read VERSIONR, it is guaranteed not to be 0 whatever configuration chip has.
