Missing "Synchrounous slave" option in SAI settings

[matyasreznicek]

I want to synchronize two SAI interfaces together, but I can not select the "Synchrounous slave" option unless I enable master block in the same SAI. I Have Master enabled in the other SAI and "External Synchro out" as well. When I enable Master in the same SAI, I can even select other SAI as the Sync input. It seems like a bug, but maybe I'm missing something. Im using CubeMX 6.12.0 and STM32H563ZIT6. Thanks

Hello @matyasreznicek @and welcome to the ST Community.

First, i suggest you try using the last version of the STM32CubeMX V6.13.0. If you still have a problem, please add your .ioc file in a comment.

Best Regards.

Thank you for response. I updated the CubeMX, but the issue persists. Here is the .ioc file. I want the SAI2A to be synchronous to the SAI1A, but the "Synchrounous slave" option is grayed out.

Thanks, matyas
