AM5726: am5726 stuck on probe pru1 iep

Part Number: AM5726

Hi, Experts

The SDK version we are using is 09_02_00_311, and the kernel version is 6.1.119.

We found that the system got stuck during startup. We shut down the printk thread and added more print information to locate the point where it got stuck in the pru1 iep register. What could be the reason for this?
