winIDEA RCU plugin: Pinpoint the cause of the last MCU reset

05-Feb-2026

RCU is a separate window of the SoC AURIX view, which displays a list of RCU registers with according value and description. It is a user-friendly representation of the reset configuration and last reset source information.


Possible solution 

1. Make sure the debug session is established. 

2. Open View | AURIX | RCU. 

In this example, the last reset happened because of a software-triggered reset, which can help you pinpoint the exact function in your source code that is initiating it. As you can see, RSTSTAT.SW bit is set.
