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
IMX95VERDIN-EVK Board
J-Link Debug Probe
12V~20V power supply
Personal Computer
Board settings
No special is needed.
Prepare the Demo
Connect 12V~20V power supply and J-Link Debug Probe to the board.
Connect a USB cable between the host PC and the Debug port on the board (Refer “Getting Started with MCUXpresso SDK for IMX95VERDIN-EVK.pdf” for debug port information).
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board (Please refer “Getting Started with MCUXpresso SDK for IMX95VERDIN-EVK.pdf” for how to run different targets).
Launch the debugger in your IDE to begin running the example.
