Tracker-4.5.3-beta1 has been released for beta testing and can be installed using MP or QGC’s beta firmwares link or it can be directly downloaded from firmware.ardupilot.org.
The changes vs 4.5.2 are in the ReleaseNotes and copied below.
- Board specific enhancements and bug fixes
- correct default GPS port on MambaH743v4
- added SDMODELV2
- added iFlight Blitz H7 Pro
- added BLITZ Wing H743
- added highres IMU sampling on Pixhawk6X
- System level minor enhancements and bug fixes
- fixed rare crash bug in lua scripting on script fault handling
- fixed Neopixel pulse proportions to work with more LED variants
- fixed timeout in lua rangefinder drivers
- workaround hardware issue in IST8310 compass
- allow FIFO rate logging for highres IMU sampling
There is one potentially serious bug that I’ve highlighted above and while it is exceptionally rare we’re keen to get this beta out as soon as we’re sure it’s safe so all beta testing is greatly appreciated.
To provide some more info on the bug
- if a lua script failed in flight (e.g. produced an error) it could actually cause the main CPU to hardfault and the vehicle would crash. This doesn’t happen every time the lua script fails though, just in rare cases with unlucky timing
Thanks in advance for testing!
