Dear Charlie and TI support team
I'm using CCS V5.1.1 to run ECU testing (I wrote these codes based on references on TI forum site).
Some additional information:
- I'm testing on TI EVM6472 platform.
- ECU version: 10.92.1.0
Here is my code:

#include "mua.h"
// Parameters
#define ECHO_CANCEL_FRAME_SIZE 80 // Frame Length
#define ECU_SEARCH_FILTER_LENGTH 1024 // Filter Length
#define ECU_FILTER_SEGMENT_COUNT 3 // Filter Segment Count

#define Y2X_DELAY 80 // Delay
// ECU Parameters

However, the results of "echo.ecu_ec_buffer" is as same as "sinBuffer". I tried many times, but can not solve this problem. I don't know how to run it to get correct results? Please help me.
Thank you and regards,
