Hello, I'm using two H533 Nucleo Boards and I'm trying to establish an I3C communication between them. There are no specific examples for this protocol using two of these boards, instead there are only examples for a sensor which I don't have. So, I tried to copy the example presented in Introduction to I3C for STM32 MCUs Application Note. This did not work. Also, I tried to adapt the example for the H503 called I3C_Target_ENTDAA_IT, copying the main.c. Also didn't work. The Target is not ack when sending 7E.
On the controller side, I'm just trying to send this:
if (HAL_I3C_Ctrl_DynAddrAssign_IT(&hi3c1, I3C_ONLY_ENTDAA) != HAL_OK){
Error_Handler();
}
On the target side, this is my code:

I also tried putting a breakpoint with the debugger at line 357 and it is not reaching it.
Any ideas what can be happening? Do you have any example between two H533 boards that I could run?
Thank you very much,
Guillermina
