a simple example of ethernet

Kam — Mon, 21 Mar 2011 23:15:02 GMT

I need a simple example of ethernet. My project just need the ethernet module send or receive a MAC frame and no need the tcp/ip protocol stack. I study "freertos_lwip","freertos_uip" and "MQX". Think that too complex to i can't understand. Could i get some document or UM about it ? And it's well if i can get a simple example. Thank you.

The K60's Ethernet controller has a compatibility mode for backward compatibility the Coldfire Ethernet module. Therefore you can also use any old Coldfire Ethernet driver code as an example.

If you are using the Tower kit you will however need to ensure that the PHY's 50MHz clock is selected (it needs RMII mode) and that this is routed over the backplane to the processor (for use as clock) since both clocks need to be synchronised for operation - see also section 7 of http://www.utasker.com/docs/KINETIS/uTaskerV1.4_Kinetis_demo.pdf
