Overview

The EDMA memory to memory example is a simple demonstration program that uses the SDK software. It executes one shot transfer from source buffer to destination buffer using the SDK EDMA drivers. The purpose of this example is to show how to use the EDMA and to provide a simple example for debugging and further development.

SDK version

  • Version: 2.14.0

Toolchain supported

  • IAR embedded Workbench 9.4

  • GCC ARM Embedded 12.2

Hardware requirements

  • Micro USB cable

  • IMX943-EVK Board

  • J-Link Debug Probe

  • 12V~20V power supply

  • Personal Computer

Board settings

No special is needed.

Prepare the Demo

  1. Connect 12V~20V power supply and J-Link Debug Probe to the board.

  2. Connect a USB cable between the host PC and the Debug port on the board (Refer “Getting Started with MCUXpresso SDK for IMX943-EVK.pdf” for debug port information).

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Download the program to the target board (Please refer “Getting Started with MCUXpresso SDK for IMX943-EVK.pdf” for how to run different targets).

  5. Launch the debugger in your IDE to begin running the example.

Running the demo

When the example runs successfully, you can see the similar information from the terminal as below.

EDMA memory to memory transfer example begin.

Destination Buffer:
0       0       0       0

EDMA memory to memory transfer example finish.

Destination Buffer:
1       2       3       4

If disable the trigger signal from XBAR, you can see the similar information from the terminal as below.
