TSC1641 I3C Interface Problem

[roro]

Hello everyone, I'm having some trouble implementing I3C communication and would like to ask for some help.

 

I am using the NUCLEO-H503RB board as my main controller. For the target devices, I have the NUCLEO-IKS01A3 expansion board and the TSC1641 (Click Board) connected. I'm currently facing some issues with the I3C communication setup between these components.

 

I have successfully managed to read the WHO_AM_I ID from the LSM6DSO (on the NUCLEO-IKS01A3). However, when I attempt to read the ID from the TSC1641, the SCL line continues to output a clock signal (or stays toggling) without a proper response. I am seeking assistance in analyzing the root cause of this issue.

How did you connect NUCLEO-IKS01A3 expansion board and the TSC1641 to NUCLEO-H503RB board? did you manage to check some hardware conflicts by referring to the different schematics?
