Hi @kjy106906
I am not really familiar with this situation. The theory of this is, that when an electronics module experiences an APB bus hang, it means that communication on the APB bus has stalled or stopped unexpectedly.
The possible reasons for an APB bus hang include:
- Incorrect bus configuration (e.g., incorrect clock settings, wrong address mapping).
- Contentions or conflicts on the bus (multiple devices trying to access the same address simultaneously).
- Faulty hardware (e.g., broken wires, malfunctioning components).
- Software issues (e.g., incorrect driver code, race conditions).
Debugging an APB bus hang involves analyzing the signals, checking the configuration, and identifying potential issues.
