This Code-Example can be used with the TC375 LiteKit and the Aurix Development Studio and shows how to use the HW-Timestamping feature of the Ethernet-MAC. It is based on iLLD drivers.
The lwIP pbuf-structure was modified to have an additional field for seconds and nanoseconds. Therfore the RX/TX timestamps can be readback easily by the application software. See the UDP echo example how it is used. Please use the project as it is, as there have been made deep modifications on the iLLD Ethernet-MAC driver.
