https://devzone.nordicsemi.com/f/nordic-q-a/114430/nrf5340-and-w5500-interrupt-handler-not-calledWe have a custom board with an nRF5340 connected to a W5500 ethernet interface. The interrupt handler for the W5500 is never executed, despite the interrupt signal being asserted. The setup NCS 2.6.0, custom board definition based on app_ns.

Result, any testable point on the PCB made it look like the signal was fine, but it wasn&#39;t actually getting to the 5340.</p> <p>So... design issue at all, just unlucky prototyping.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/501045?ContentTypeID=1Tue, 03 Sep 2024 22:35:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a5e4895-1832-4303-a127-a5e7ad3dd825Sigurd<p>Hi!</p> <p>1) Is this with your custom board, or the nRF5340-DK ?</p> <p>2)</p> [quote user=""] (P1.02 being read high when we are measuring it low),[/quote] <p>Maybe some pullups on here, and it&#39;s not pulled low enough?</p> <p>High on nRF53 is when the voltage is higher than VDD*0.7 , low it&#39;s when it&#39;s lower than VDD*0.3</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1725402842464v1.png" alt=" " /></p> <p>3)</p> [quote user=""]even when the pin is measured low:[/quote] <p>Did you measure the voltage?</p><div style="clear:both;"></div>
