How to read or write data by I3C btween IKS02A1 and NUCLEO-H503RB

I'm trying to check I3C protocol between IKS02A1 with NUCLEO-H503RB.

and I just followed the guide which is below link.

And I also tried I3C_Controller_Private_Command_IT code from the github.

But it seems there is NACK from the SLAVE. I've attached the scope shot.

Maybe I missed something of board setting? please give me some advice.

Thanks.

Hello @LukeJang522 ,

Could you please use X-NUCLEO-IKS01A3 because IKS02A1 doesn't support I3C protocol .

Let me know!
