Real audio frequency and error between selected in SAI for the STM32N6 showing 0

csaji · ‎2026-05-04

Hello,

I'm trying to configure my SAI to receive TDM packets from my external ADC. For some reason, no matter what sample rate I choose, the real audio and error between selected is always 0. I've tried changing the clocks to the SAI1 module to 50 and 100 MHz, but it didn't change anything.

Is this a visual bug with CubeMX or is it something with how I'm configuring the peripheral?

Thanks.

Hello @csaji

Thank you for posting!

Actually, this is a known issue in CubeMX tracked by Internal ticket number: CDM0059442 (This is an internal tracking number and is not accessible or usable by customers.), And our development team is actively working on a resolution. I will keep you informed as soon as I have any updates.

Opening an internal ticket is not a solution.
There are many issues marked as “resolved by opening a ticket” that have been on ASAP for years.
