i.MX RT 1064 EVK audio example

I have an i.MX RT 1064 and I have installed the MCUXpress SDK with FreeRTOS feature.

The helloworld example is working fine.

I need to verify the audio output of the EVK and ethernet functionalities - in FreeRTOS.


I tried the examples for audio - evkmimxrt1064_dev_audio_generator_freertos, evkmimxrt1064_dev_audio_speaker_lite_bm, evkmimxrt1064_dev_audio_generator_lite_bm, evkmimxrt1064_dev_audio_speaker_bm, evkmimxrt1064_dev_audio_generator_bm. But none of these gives any audio output on the head phone connected to the audio jack. I tried debugging and enabled the macro - USB_DEVICE_CONFIG_USE_TASK to 1U, but still no result and no error.


Can you please let me know if I am going in the right direction?
