Introduction

Demostrates a simple example of auto increment DMA to allow DSP to operate a function on internal memory and transfer back the result with compression.

The application runs on C7x core. UDMA is configured for UTC/DRU mode.

Supported Combinations

Parameter	Value
CPU + OS	c75ss0-0 freertos
Toolchain	ti-arm-clang
Boards	am62ax-sk
Example folder	examples/dmautils/dmautils_autoinc_compression/

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run and Running SMP FreeRTOS application on A53
