What is the maxim sustained data rate on the Ethernet interface on the K64? Is there example code available to demonstrate this on the K64 Freedom Board?

Hi,

Please have a look at FNET [bench] example for FRDM-K64F board about Ethernet throughput.

Wish it helps.


Have a great day,
Mike

Hi Mark

You will need to be more precise as to the protocol to be used to get meaningful values.
For example, if you are sending jumbo frames you will easily achieve 100Mb/s but if you are using TCP it will be very much dependent on the stack used and the buffer sizes available and allocated. UDP will give higher sustained throughput due to lower SW overhead and not buffering requirements.
Also the network activity will also be a factor in a real system which may reduce the throughput at no fault of the K64.

Regards

Mark
