STM32 H563ZI as I3C target does not respond to DAA CCC

Hello,

 

I have 2 NUCLEO-H563ZI boards connected to each other as required, one running the "I3C_Target_Private_Command_IT" example and the other running the "I3C_Controller_Private_Command_IT", i also have a logic analyzer connected to monitor the I3C communications, however the setup is not working as expected, the "target"  ACKs the initial broadcast from the "controller", but NACKs the subsequent broadcast after the "ENTDAA" CCC

Any thoughts on what could be wrong here ? I tried debugging but the "target" board simply does not seem to be observing any interrupts/events during this whole "ENTDAA" CCC transmission from the "controller"
