We have a camera that can record, and the SOC records through the I2S interface. Is there a driver patch recording only? What reference documents are there? The IO of our three I2S are mcasp1_ AXR2， MCASP1_ ACLKR， MCASP1_ Is FSR correctly designed?

Hi,

Are trying to record in vision SDK?

If you are using the vision SDK then mention the SDK version.

Thanks

Hi,

I'm not sure about utility or driver patches for camera recording through the I2S interface.

So why don't you use a link-chain framework to record camera images?

You just need to create the following use-case chain

Capture -> Null

The Capture link will capture the frames from the camera

The Null link used to save the data in a file.

Thanks

Hi，

In this way, only images can be saved, not recorded. The sound is transmitted through the I2S interface.

Hello,

Can you take a look to see if you have arecord in your filesys, if so, you can use:

arecord -Dplughw:0,0 -t wav <path to wav file>

Some documentation at:

software-dl.ti.com/.../Audio.html

This is a different SDK. I dont have visionSDK installed.

regards

Jian
