Hardware requirements#
USB Type-C cable
Loopback network cable RJ45 standard
MCIMX93-QSB board
Personal Computer
Board settings#
No special settings are required.
Note#
Please run the application in Low Power boot mode (without Linux BSP). The IP module resource of the application is also used by Linux BSP. Or, run with Single Boot mode by changing Linux BSP to avoid resource conflict.
Prepare the Demo#
Connect a USB cable between the host PC and the OpenSDA 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(J501).
Download the program to the target board.
Either re-power up your board or launch the debugger in your IDE to begin running the demo.
Make loopback cable: 568B standard Unknowed standard 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 568B standard or the other standard. 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 terminal like:
ENET multi-ring txrx example start.
30 frames will be sent in 3 queues, and frames will be received in queues. The frame transmitted from the ring 0, 1, 2 is 10, 10, 10! 30 frames transmitted succeed! The frames successfully received from the ring 0, 1, 2 is 10, 10, 10!
