enet_txrx_multiring_transfer#
Overview#
The enet_txrx_multiring_transfer example shows the way to use ENET driver to
receive and transmit avb frame in the avb feature supported multi-ring platforms.
this example is only supported in multi-ring platform.
This example shows how to initialize the ENET MAC.
How to use ENET MAC to transmit frames in avb supported multiple-ring platforms.
The example transmits 30 number frames. For simple demo, we create frames with some special definition.
Build transmission frames with broadcast mac address.
Build different frames for each ring: 10 normal ethernet frame, 10 similar IEC 61883-6 type frames, 10 similar IEC 61883-8 type frames and the two IEC 1722 avb frames are set with different vlan priority .
Notice, To simply show how to use three different rings in rx/tx on one board. This example set PHY local loop and you will see there will be PHY init auto-negotiation fail and this is normal. because phy can not finish auto-negotiation when phy is in loop back mode. However, the auto-negotiation fail has no impact on this loop back example, so just forget about the failure auto-negotiation.
Supported Boards#
EVK-MIMX8MM
Hardware requirements
Micro USB cable
MIMX8MM6-EVK board
J-Link Debug Probe
12V power supply
Loopback network cable RJ45 standard
Network cable RJ45 standard
Network switch
Personal Computer
Board settings
J501 connected with network switch through RJ45 network cable. Two types of base boards(ENET PHY is RTL8211F or AR8031) are supported and the default is for RTL8211F. For base boards with ENET PHY AR8031(older version than RevD) need define macro “EXAMPLE_ENET_PHY_PHYAR8031” to 1 in example source code.
Please note this application can’t support running with Linux BSP! This example aims to show the basic usage of the IP’s function, some of the used Pads/Resources are also used by Cortex-A core.
Prepare the Demo
Connect 12V power supply and J-Link Debug Probe to the board, switch SW101 to power on the board
Connect a USB cable between the host PC and the J901 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 into network switch device(support loopback frames) and connect switch to the board’s Ethernet RJ45 port.
Download the program to the target board.
Launch the debugger in your IDE to begin running the demo.
Make loopback network cable: Standard 1 Standard 2 J1 orange+white green+white J2 orange green J3 green+white orange+white J4 blue brown+white J5 blue+white brown J6 green orange J7 brown+white blue J8 brown blue+white
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 the sheet above. If your cable’s color order is not showed in the list, please connect J1~J8 based on your situation.
Running the demo
When the demo runs, the log would be seen on the debug terminal like:
ENET multi-ring txrx example start. The 0 frame transmitted from the ring 0 ! The frame received from the ring 0, 1, 2 is 1, 0, 0 now! The 1 frame transmitted from the ring 1 ! The frame received from the ring 0, 1, 2 is 1, 0, 1 now!
……
