how to implement DHCP in FRDMK64

[sudhakarp]

HI,

i am using FRDMK64 board and i am using KDS3.0 ans KSDK1.3.0 Example. i want to implement DHCP in Ethernet_to_serial example. if anyone guide me how to do..?

is any DHCP example code available..? Actually i dnt know how to get IP address from DHCP server. i need initialization code to get IP address.

regards,

sudhakar p

Hello sudhakar p,

You can find the eth_to_serial example located at the path:  C:\Freescale\KSDK_1.3.0\middleware\tcpip\rtcs\examples\eth_to_serial

This example uses a static IP, however you can modified the example according your needs. In order to do that it is necessary to modified the demo.c file. Below you can find and example that you can use as reference.

Please let me know if this helps!

Have a great day,
Sol
