Overview
========
CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide
range of supported microcontroller devices. The API connects microcontroller peripherals with middleware
that implements for example communication stacks, file systems, or graphic user interfaces.
More information and usage method please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.
The cmsis_enet_transfer example shows how to use CMSIS ENET driver:
In this example, the ENET transmits 20 number broadcast frames and will print the received frame.
Toolchain supported
===================
- IAR embedded Workbench 9.30.1
- Keil MDK 5.37
- GCC ARM Embedded 10.3.1
- MCUXpresso 11.6.0
Hardware requirements
=====================
- Mini/micro USB cable
- Loopback network cable RJ45 standard
- EVK-MIMXRT1020 board
- Personal Computer
Board settings
==============
No special settings are required.
Prepare the Demo
================
1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
2. Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
3. Insert loopback network cable to Ethernet RJ45 port.
4. Download the program to the target board.
5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Make loopback network 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 example start.
