Any reason to expect different compass behavior with this release? MP reported “compass not calibrated” after updating from Rc4 (chibios both). And the 2nd on-board compass on the PixRacer is not recognized when doing the calibration. I think this can be seen in the device ID’s comparing them to the Rc3 release which is the last I have a saved parameter file from. They are identified differently.

Hi I like to install using load custom firmware can you give me the direct link to the directory for px4-v3 rc-5? I am lost. normally it in the latest directory? but the firmware does not say RC-5 after loading unless I use MP load beta. Where is MP pointing to?


(Pete) #7

I think MP temporarily downloads them each time, should be here : http://firmware.ardupilot.org/Copter/beta/


(brandon macdougall) #8

Ok that did it. I see RC-5 now. Thanks!

ChibiOS rc-5 on the mRo in gps mode is jerky see video: GPS switched on at 00:13

logs ChibiOS and Nuttx nuttx is fine.


(brandon macdougall) #10

Downloading logs in RC-5 gives false flags errors. Nav check, Bad ARS, and Pos vert in HUD.


(rmackay9) #11

Dave,

That is a bit of a concern. There was a change related to the compasses. It was meant to be a non-functional change but perhaps something went wrong. Txs for the report. I think we should be able to reproduce with a pixracer but we may need a dataflash log file from you…


(rmackay9) #12

Brandon,
Txs for the report. re EKF errors during dataflash log downloads, I think that happens in Copter-3.5 as well. It’s potentially something we should fix but we may not fix it in Copter-3.6.

Randy,
Flight log attached from a brief hover as it wasn’t stable in assisted modes.

Edit: I flashed back to 3.5.5 Nuttx as it wasn’t flyable on 3.6.0Rc5 Chibios and the compass’s are properly recognized and calibrate OK.


(rmackay9) #14

Brandon,

Nice video and logs of the problem. I’ve created a new thread here to discuss.


(tridge) #15

@quadsours many thanks for reporting the issue with the mRo X2.1. I’ve reproduced the issue and fixed it in master and for copter 3.6.
I’ve done a build here for you to test:

(brandon macdougall) #16

Great, thanks for testing so quickly! This will be included in Copter-3.6.0-rc6 which will be out within a week I think.

report:

Quad nose dived in takeoff and crashed.

IronMan 650 Sport
400kv
ESC XRotor Pro 50A
3.6.0-rc5 Pixhawk 4
stabilize mode.

When I started the takeoff all seemed stable, but at about 3 feet the quad took a nose dive and landed on its back. Ended up with only one broken antenna.

Actually I have a hunch that the cause is due to mechanical failure but I’m not sure. I am not proficient enough in reading the logs so any input would be appreciated.
