Constant SCL Ticking with I3C Controller on STM32H563ZI

[RonenW]

Hi,

I'm using the I3C_Controller_HotJoin_IT example on the STM32H563ZI.

After initialization, when a Target device is connected to the I3C bus, the controller continuously activates the SCL line.

This behavior does not occur when the Target device is another STM32H563ZI running the I3C_Target_HotJoin_IT example.

Has anyone experienced this issue or can suggest a possible workaround?

Thanks, Ronen

What do you mean by when the Target device is another STM32H563ZI?

If replacing the board solves the problem, it means the original board is damaged.
