Version Number does not get displayed succesfully

Hi all,

I have a small problem with my W5500 chip. I had successfully written code for it before, and have reused the same logic parts for this. However, nothing works. And i am a bit stuck as to why.

Below is my code, one thing that i noticed is that my RST pin seems to be high all the time. Even after the reset. This might mess with things? Please let me know your thoughts.

You’d better reset chip using reset pin properly as advised in the datasheet.

This does not help, you must give details what and how exactly it does not work, and how you believe it must work. If you reused the code and it was working within previous hardware, then logically, as you guess, something has changed in the hardware - try comparing the circuit diagrams.
