- Please send more ideas
Remaining PRs for v1.14 RC
- Optical Flow Fixes by AlexKlimaj · Pull Request #21769 · PX4/PX4-Autopilot · GitHub
- Optical flow: pre-flight check improvements by bresch · Pull Request #21789 · PX4/PX4-Autopilot · GitHub
The PRs will be merged, as it has been reviewed and tested. Backport PRs will be created. Mathieu will do that. This is the only remaining release blocker PR.
Will merge and make changes to Gazebo side, to make Rover functional. Note, Matthias tested with SITL after it was merged, and found that QGC sends different range for rovers 
(Using QGC and Joystick).
- Fix mag offset correction from estimated bias by bresch · Pull Request #21812 · PX4/PX4-Autopilot · GitHub → Regression from v1.13
For v1.14 backport, we will modify the PR to keep the 30 seconds limit (instead of 10 sec).
-
FMU v5 flash overflow needs to be resolved
Note: The Geofence param default value change was only included to v1.14 branch, and not in main branch, we need to make sure backports are done after main branch merge.
Miscellaneous bug reports on v1.14 beta
-
[Bug]: Runway Takeoff / Landing bugs and problems. · Issue #21774 · PX4/PX4-Autopilot · GitHub
-
Airspeed Calibration not working on Pixhawk 5X VTOL Firmware · Issue #19088 · PX4/PX4-Autopilot · GitHub → Unsure if this is still happening, it should have been fixed. Waiting for user feedback on this as well. Contacted Ryan for testing.
-
Cube Orange Plus target for beta not available in S3 bucket: [v1.14 beta] - Flight testing & Flight Issues (logs) · Issue #21358 · PX4/PX4-Autopilot · GitHub
We will do the pass again in Jenkins compile pipeline.
It seems like there’s 3 S3 deployment Jenkins pipelines:
High vibration levels
- Accel 1 Clipping with PX4, no problems with Arducopter - #4 by mwshafer
- High vibrations: PX4 v1.14.0 (beta) on Pixhawk Cube Orange Plus
- High vibration in Cube Orange+
Calculations for the vibration metrics have changed from v1.12 to v1.13 (Alex), and shows differently on Flight review.
TODO: We prob should have renamed the fields to keep the plots consistent.
