Internal Error 0x20000000 - FailSafe triggered

Trappify · September 10, 2024, 12:19pm

Hi,

I’m running Rover 4.5.6 on Matek H743 Slim V3. Today when in Auto, after reaching about 17 waypoints successfully (approx 7km distance) I got an Internal Error 0x20000000 and failsafe was triggered.

What does Internal Error 0x20000000 mean? Is there a doc for those internal errors somewhere or do I have to dig into the code?

BR
Andreas

This page is for anyone to report an Internal Error ("Internal Error:" in GCS or… DataFlash messages). This allows the Dev team to be alerted, and to investigate as soon as possible. Please enter the firmware used, vehicle type, and the Internal Error message. If you have a log, please retain it for 30 days in case a Developer would like to examine it. Note: follow up timing on a new issue will depend on many factors, so some may not be addressed immediately. The [list of internal error numbers and meaning can be found here](https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_InternalError/AP_InternalError.h#L40).

Thanks! But not sure what to make of it. Perhaps there are more details buried in the logs if I pull them from the FC.

    gpio_isr                    = (1U << 25),  //0x2000000 33554432

seems to be related to some interrupt thing.
