Trouble getting SAI Master output signals (MCLK, FS, SCK) on Nucleo H723

[MHoop.1]

I am trying to add SAIA support to my CubeIDE project on a Nucleo-H723. I have configured SAIA as Master with Master Clock Out and expect to see MCLK, FS, SCK at pins 14, 16, and 18 on CN9, but there is no output. Shouldn't these signals appear after initializing SAIA?

Make sure you supply kernel clock to given SAI module.

Read out and check related RCC , SAI and GPIO registers' content.

The clocks usually start only when you start some kind of transfer.

You are correct!
