Hello and thank you for your post.

Could you please be more specific as to what Soft-UART you are referring to?

Thank you.

My product needs to use 10 serial ports, so I need to use PRU to extend four soft-uart, but I found nothing about it in the new SDK.For example，no firmware，no driver code...

Thank you for the additional information. We have plans to add this feature in an upcoming SDK later this year, but it is not available today.

I'm sorry, we don't have an example of using SUART with a more recent SDK. Thus, we can't support the effort of porting this, as we haven't done it. Our plan is to release a new, fully supported example in the next few months.
