LPC1857 TCP/IP packet loss

Hi friends! I am facing a problem with TCP/IP packet loss. My circuit uses the LPC1857 microcontroller and as an interface for the ethernet connection I use the LAN8720 IC. What could be causing the loss of many packets in the ping test for example?

Thanks a lot!

Hi,

This is my guess, maybe the core is overloaded, pls remove or disable the other interrupt, enable only the ethernet interrupt and have a try.
