AM2431: How to set the IN endpoint to NYET or the OUT endpoint to NYET during data transfer?

Part Number: AM2431

hello:

I am working with USB in device mode, and I would like to set the IN endpoint to NYET or the OUT endpoint to NYET during data transfer. How can I modify the Cadence USB IP core code to accomplish this?

Hello,

Apologies for the delayed response.

Can you please tell what is the exact use case for setting endpoint to NYET?

thanks！

During the device enumeration process, I want some endpoints to reply with nyet and others with ack. For example, my endpoint 1 is the cmd endpoint, while endpoint 2 is the data endpoint. I want the state of endpoint 1 to be nyet and the state of endpoint 2 to be ack. How can this be achieved?

Hello HE,

Thanks for your patience.

I have checked the driver code. Unfortunately, Sending NYET packet is currently not supported.
