# w5500 not working

## Question

Asked by Mohamad Bazeih on 2019-06-11 in Ethernet Chips.

Dear friends
I have w5500 implemented in a PCB as per the attached schematic. I tested it on 5 different PCB’s (the same design) and it is not working. Knowing that i have tested the software on w5500 shield and it is working normally hence no issue with the software. Could you please have a look at design and let me know whats wrong.

> it is not working

What is wrong? What exactly does not work? Do yo uhave link LED on when put cable in? Can processor read registers through SPI and does it read correct infomration?
