Plot code LPCOpen TCP echo example from MCUXPresso to Keil for LPC1778

Dear expert,

Im struggling troubleshoot the issue that my LAN doesnt respond to the ping. I have build & run using the TCP echo & webserver example using MCUXPresso for my LPC1778 and its working. However, after plot into keil, the LAN doesnt respond to the ping. Its only managed to initialize & detect if the link is up or down. Please help me. Below it the debug print from both IDE, it is identical. Attached the code for keil.

Hello @aus_swsol

You can directly download LPCopen for Keil, which includes a TCP demo within it.
