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.
