Question
I3C Controller Initialization Problem
Hello,
I have a project that uses I3C to connect a Nucleo-C562RE with an STM32C542CCT6 MCU. The setup was working fine with HAL 2.0.0 but it does not work in 2.1.0. I generated the code with MX2 and I observed that it is identical to the code in the private_it_controller example code. I stepped through the mx_i3c1_init function and I noticed that the moment the GPIO for SDA and SCL are enabled, the I3C clock (SCL) is turned on (visible on the oscilloscope) and does not stop. I don’t see how this could be correct. When I try to start DAA it fails instantly (the error callback is invoked) and the SDA line never changes state (it stays HIGH after reset).
Can someone help with this issue?
Thank you,
Gil
