Warning #1: PX4/Pixhawk users upgrading from AC3.1.5 (or earlier) may need to re-do their compass and accelerometer calibration because AC3.2 also uses the backup compass and accels. Pre-arm checks have been added to ensure this has been done.
Warning #2: on the APM2.x the logs must be downloaded using MAVlink instead of the terminal.
AC3.2-rc14 is now available for BetaTesters through the mission planner’s Beta Firmwares link. The full release notes can be found in ReleaseNotes.txt and changes from -rc13 can be seen below.
Feel free to raise issues found during testing on this discussion or in the new support section in the APM Forum.
It’s a big release with “the onion” restructure and a bunch of new features (including these 57 closed items) so we need to re-test almost everything including all flight modes, all mission commands and all the new features. Marco and I will be maintaining (and adding to) this testing list. Issues reported will first be checked by Jonathan, Marco and I and then confirmed bugs/issues will be put on the github issues list (and then hopefully fixed).
Thanks especially to the beta testers who put their copters at risk testing each release. Enjoy!
Changes from 3.2-rc13
1) Safety Features:
a) fail to arm if second gyro calibration fails (can be disabled with ARMING_CHECK)
2) Bug fixes:
a) DCM-check to require one continuous second of bad heading before triggering LAND
b) I2C bug that could lead to Pixhawk freezing up if I2C bus is noisy
c) reset DCM and EKF gyro bias estimates after gyro calibration (DCM heading could drift after takeoff due to sudden change in gyro values)
d) use primary GPS for LED status (instead of always using first GPS)
Can someone please tell me how to skip just the gyro calibration pre-arm check? If I set pre arm check to '0' that disables all of them [ compass etc ] but all I want to do is skip just the gyro. I need to do this to arm on a moving boat until 'boat mode' gets the green light in 3.4. I hope...
ARMING_CHECK_INS = 0x10
Although note this skips all the INS checks including accelerometers.
Also note that in 3.3 these checks were specifically strengthened to fail pre-arm checks if the FC is moving over a certain threshold when arming such as on a choppy boat, as if this is allowed then as I understand it the FC can't then keep attitude control. In other words, bypassing this is a Very Bad Idea :)
Thanks. Yea I agree probably not a good idea. Guess I'll wait for a better solution in 3.4
Hi, Rich B
Now, I got the same issue "Initialising APM" with pixhawk, How did you solve it? can you help me?
I'm still encountering a similar issue with the Geo Reg Images utility in MP-1.3.32. Pre-process appears to only work for me when 'Use AMSL Alt' is unselected. If this is selected, the utility prints the error "Log file problem. Aborting". I'm still using AC3.2_RC10, and wondering whether there's been a change in the position (log offset) of the AMSL value in the logs?
FYI.... WAAAAAAyyyyyy back in this thread somewhere I posted a problem about and issue were after going to 3.3 from 3.2 my teesny and lue script for my taranis telemetry was broken. It worked fine until I fired up a GCS station the instant I did that and connected the Taranis telem acted weird... useless. I FINALLY figure out it was because I needed to snip the red wire [ and I didn't blow up yea!!] which was the TX from the teensy RX on the tellem 2 on the pixhawk. Now it seems to work fine. If anybody knows why that is I would sure like to know!
