Kinetis K40x256 Tower with TWR-SER Ethernet Example?

thales_user1 — Wed, 19 Oct 2011 16:33:24 GMT

Hi there,

Note: I accidentally posted this message in the wrong forum, so if you have already seen it apologies.

We have just purchased a couple of Kinetis K40x256 Tower evaluation boards. We are using the IAR v6.21 IDE to build and load the software to the board. We are able to use the TWR-K40X256_Quick_Start_Demo, however we cannot find any help or documentation on how to interface with the TWR-SER peripheral board, specifically how to drive the Ethernet port.

What we are really looking for is an example and/or instructions on how to drive the Ethernet port on the TWR-SER via the tower bus interface from the TWR-K40x256. Failing that we would appreciate a point in the direction of some documentation.

The closest things we have found are the 4-page leaflet in the TWR-SER box which describes the jumpers we need to set for Ethernet usage and the K40 tower user manual, which is similarly quite light on information.

Any help, greatly appreciated.

Best regards

The K40 doesn't have an Ethernet controller and so it can't be used with the Ethernet port on the TWR-SER board.

To use Ethernet you need the TWR-K60N512 processor board.

I am using K60N512 , and downloaded TWR-K60N512 processor board programs, but i din't find ETHERNET application on that.

is there any application code on Ethernet?

For bare Metal Examples get the "Kinetis_SC" sample code

If you are interested in an RTOS, MQX has a bunch of ethernet application examples for the K60 board.
