mcx_enet_txrx_rxpoll#
Overview#
The enet_rxtx_rxinterrupt example shows the simplest way to use ENET functional tx/rx API for simple frame receive and transmit.
This example shows how to initialize the ENET.
How to use ENET to receive frame in polling and to transmit frame.
The example transmits 20 number broadcast frame, print the number and the mac address of the recieved frames.
Supported Boards#
FRDM-MCXA577
Hardware requirements
Type-C USB cable
FRDM-MCXA577 board
Personal Computer
Loopback network cable RJ45 standard
Board settings
Short position 2-3 on J29.
Prepare the Demo
Connect a USB cable between the host PC and the MCU-Link USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Insert loopback network cable to Ethernet RJ45 port.
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
The example uses external PHY over RMII by default. If you want to use the internal 10BASE-T1S digital PHY, redefine BOARD_NETWORK_USE_TENBASET_PHY from board.h to 1 and rebuild. Loopback cable is not needed in that case.

Connect J1 => J3, J2 => J6, J4 => J7, J5 => J8. 10/100M transfer only requires J1, J2, J3, J6, and 1G transfer requires all 8 pins. Check your net cable color order and refer to 568B standard or the other standard. If your cable’s color order is not shown in the list, please connect J1~J8 based on your situation.
