Sending data using "Raw Ethernet"

Hello,

How do you send raw Ethernet data using the K60 MAC?

I don't necessarily need to do this using an OS. But if there is a procedure in MQX to do this, that would be OK.

Part of the problem I'm having is that I can't seem to find out how to do direct writes to the Enet transmit FIFO. Where is it located? The RM has no FIFO register specified.

I see now that you don't have direct access, but need to set up the transmit uDMA buffer descriptor TxBD.

The KINETIS_SC includes two examples for ENET application, though they are both based on FreeRTOS, but if you dont like the OS , you may also use the ENET driver for your application.
