Introduction

This example demonstrates the error handling functionality of EDMA. A Count, B Count and C count are set to 0 to emulate a NULL transfer. After starting the transfer, EDMA detects a NULL transfer and signals TPCC error. Application error callback gets invoked which signals an error.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
	r5fss0-0 freertos
Toolchain	ti-arm-clang
Boards	am263px-cc, am263px-lp
Example folder	examples/drivers/edma/edma_error_interrupt/

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

Sample Output

Shown below is a sample output when the application is run,

[EDMA] TPCC Error detected due to NULL transfer on below EDMA channels -
[EDMA] Channel: 0
[EDMA] Error Transfer Test Completed. Null tranfer error detected !!
