Regarding i.MX8M SAI pins and Boot Pins Multiplexing

We are designing an infotainment system using i.MX8M processor.@

In this design, we need 2 SAI audio ports (SAI0 & SAI1).

The SAIx pins of i.MX8M are also used as Boot GPIOs.

 

We need to clarify whether we can use the SAIx pins as both boot pins as well as SAI audio pins?

In Pinmux tool, we are getting a conflict while assigning the same.

 

Please find attached a snapshot from our design.

 

Appreciating your immediate support....@
