Overview

This file contains a example for using EmacLite hardware and driver.

This file contains an interrupt example outlining the use of interrupts and callbacks in the transmission/reception of Ethernet frames using MAC loop back in the PHY device with an incrementing payload from 1 byte to 1500 bytes (excluding Ethernet Header and FCS).

This example assumes that there is an interrupt controller in the hardware system and the EmacLite device is connected to the interrupt controller.

Note

None

MODIFICATION HISTORY:

Ver   Who  Date     Changes



2.00a ktn  02/25/09 First release
2.01a ktn  07/20/09 Updated the example to wait for either Transmit complete
                    or Rx packet reception.
3.00a ktn  10/22/09 Updated the example to use the HAL APIs/macros.
              Updated example to use the macros that have been changed
              in the driver to remove _m from the name of the macro.
3.01a ktn  07/08/10 Updated example to support Little Endian MicroBlaze.
4.3   ms   01/23/17 Added xil_printf statement in main function to
                    ensure that "Successfully ran" and "Failed" strings
                    are available in all examples. This is a fix for
                    CR-965028.

int EmacLitePhyLoopbackExample ( u16 DeviceId )

The main entry point for the EmacLite driver PHY loop back example in interrupt mode.

This function will transmit/receive the frame using MAC interface loop back (in the PHY device) and verify the data in the received frame.

Parameters

DeviceId is device ID of the XEmacLite Device , typically XPAR_<EMACLITE_instance>_DEVICE_ID value from xparameters.h.

Returns: XST_SUCCESS to indicate success, otherwise XST_FAILURE.

Note: None.
