RTOS/TMDSEVM572X: McASP DSP example issue

AFUA KOFF

Prodigy 130 points

Part Number: TMDSEVM572X

Tool/software: TI-RTOS

I imported the MCASP_DeviceLoopback_evmAM572x_c66ExampleProject.

I rebuilt the project and loaded into the dsp1.

Plug in an audio feed into the Audio In Port.

Connected a headset to the Audio Out.

Run the program, but I cannot hear the audio feed.

Am I missing something. Am new to the way MCASP3 and AIC_3104. Any help

AFUA,

MCASP Device Loopback is internal device loop back Of the TX/RX data this doesn`t take data input from AIC but passes reference input data and confirms that through internal loopback the data was received correctly. Notice in the project you don`t have any AIC configuration or data.

In order for AUdio loopback using AIC3106, you need to build and run the MCASP_Audio_evmK2G_c66ExampleProject or the MCASP_Audio_evmK2G_armExampleProject.

Please build and run this example and let us know if you are still running into issues with the audio feed.

Regards,
Rahul
