I tried to use these pins for general SPI seems GPIO 9 didn't like to be used as a CS pin if switch that it works.

ethernet:
  type: W5500
  clk_pin: GPIO05
  mosi_pin: GPIO04
  miso_pin: GPIO13
  cs_pin: GPIO09
  interrupt_pin: GPIO10
  reset_pin: GPIO12

I then swapped them to

ethernet:
  type: W5500
  clk_pin: GPIO42
  mosi_pin: GPIO44
  miso_pin: GPIO40
  cs_pin: GPIO39
  interrupt_pin: GPIO41
  reset_pin: GPIO43

and it worked.

Any idea why? I think it was because of GPIO 9 and using some pins in the FSPI pin layout not in the order it wants
