Question

SAI1-A and SAI4-A don't have synchronous slave option in LQFP100 package

Hello,

Using STM32H753VITx with STM32CubeMX 5.1.0, I would like to use SAI1-A as 'Master with MCO' and external synchro out, and SAI4-A as synchronous slave.

SAI4-A doesn't show the synchronous slave option.

Alternatively I could do it the other way round, with SAI1-A slaving synchronously to SAI4, but that doesn't appear as an option either.

With the LQFP144 and LQFP176 packages I can select these options.

I don't believe there is a pinmux issue, as the SAI1/4 data pin is not used by any other SAI.

Is this just a problem with CubeMX or is there an underlying limitation of the LQFP100 package that is causing this?

Thanks and best regards,

Kieran.

Thanks Khouloud,

Great to hear it's not a limitation of the smaller package/pinmux. We'll code around the issue for now and look forward to the next CubeMX release.

Best regards, Kieran.
