Why can't I enable all 4 SAI ports on STM32H750/STM32H743?

caleb · ‎2019-06-11

Hello,

I am attempting to use all 4 sai ports as one large synchronous audio device.

The I want SAI1A to be the master, and SAI1B, SAI2A, SAI2B, SAI3A, SAI3B, SAI4A, SAI4B to all be synchronous slaves to the SAI1A.

I am able to configure them all, except for SAI4B, which says it's in conflict with SAI1B synchronous slave. I'm using the internal synchronous signals, all synchronous slaves are marked as, "Synchronous with other SAI, SAI1". But just 4B says it's in conflict.

I assume if I configure it manually, it'll probably work fine...

Thanks
