Dear All,

My current job is to develop a TCP/IP program for LPC1769 on Mbed lpc1769 development board.
For last one month I am working hard to run any demo of TCP/IP or LWIP on this hardware using lpcxpresso IDE.
this LPC1769 has DP83848L PHY chip and all demo programs are failing.

Please suggest me any working demo for this h/w,  it is very urgent.

Thanking You.

Currently tried all demo programs from lpcxpresso suite and lwip-skel demo found on Net.

After not finding any working demo I had to look deep into code and I found difference in PHY chip used. With a lot of effort I could compile demos for this pPHY but none works. need especially LWIP demo which could be run.

The demo's are written for the LAN8720 PHY chip. So the demo's won't work out of the box.
Personaly i don't have any experience with the DP83848L from TI.
