i.MX RT 1064 EVK audio example

radhikakrishnan — Tue, 25 Jun 2019 05:45:35 GMT

Hello,

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?

thanks,

Radhika

Hi Radhika Krishnan ,

Please tell me which SDK version you are using?

Do you use the following project?

If you are not using the SDK2.6.0, please download the newest SDK from this link:

Welcome | MCUXpresso SDK Builder

and try it again.

If you still have questions about it, please kindly let me know, I will help you to check it.

Have a great day,
Kerry

Hello Kerry,

I am using SDK version 2.6.0 and the project is same as you showed.

Is the project expecting a USB microphone input? I could not understand which audio source is being used to play in the speaker.

regards,

Radhika.

Hi Radhika Krishnan,

Thank you for your updated information.

Do you check the readme.pdf in the project? That readme tell you the detail project information.

Take the MIMXRT1064-EVK board as an example. J9 usb port is the audio port after you download the code to the RT chip.

This is my test result:

When you plug the J9 to your PC, you will find that USB is the audio port.

More details, please check the readme.pdf.

Wish it helps you!
Have a great day,
Kerry

Thank you, kerryzhou

It worked.

Is there any examples to use the ethernet port of the IMX RT1064 EVK?

regards,

Radhika.
