Here is my second support request:
Since the uBrain came with AC3.2-rc2, I wanted to update with rc7 .
The MP (recent version) shows this :
Question is , since the MP takes .hex files and .vrx and both are offered @ by the VR FW package...which one to choose, v51.hex or v51.vrx ?
Thx for help !
Now -rc9 is out and contains a FRAM bugfix.
1) FRAM bug fix that could stop Mission or Parameter changes from being saved (Pixhawk, VRBrain only)
Question: Do this fix apply to the uBrain as well ?
Now the upload topic is solved. I was able to take it out of the VRX_binary-master and used the .vrx file.
But its much better now, since emile announced, that the recent sum rx version (-rc9) is hidden behind the 3.15 button. Thx. This is far more comfortable, since I am used to do every beta (stable).
Tested -rc9 with uBrain @ F450. LOITER,ALT,STAB,LAND work w/o recognizable issues. Small ALT jump, at the moment when EKF is turned on, but not scary, maintains height perfectly. Thx.
I'm happy that you test EKF and all work fine :)
About rc9 the first revision was compiled without sbus support , now we solve it and re include it .
Hi Roberto, EKF was the main reason, I prefer the uBrain over the Mini Versions of the APM. I am pretty sure that this great step ahead will be a standard pretty soon and bury other platforms not being able to handle . SBUS is important as well.Thx.
Is it possible to continue placing the recent rc Versions of AC3.2 behind the AC3.15 Button @ Mission Planner ? Since rc10 came out,that would be a great service.
3.2 rc10 is online with APM mission planner. I had some success with my Vr Brain 4.5 but no way to do it via APM mission planner with my µBrain. I had to download firmware archive and make a DFU file for dFuse demo to upload firmware.
My µBrain is really USB twitchy.
Thx Marc , it worked for me , I already did the upolad to ubrain with MP yesterday night and tried it this morning , which wasn´t too lucky though, probably due to bad GPS reception.
Concerning USB , I´ll have to find someone for soldering some very thin wires to a naked USB plug for extension, because I almost rip of my vib damping when I try to reach the uBrain USB plug, hidden between my centerplates. It won´t survive too many log downloads ;-)
-rc10 now works well as well as the -rc9 did. It wasn´t GPS reception...My MAG calibration has been messed up, and -rc10 requires reboot after flash.. I´m not sure about different EKF behavior. Switching between DCM / EKF still causes slight ALT / YAW changes. But not really scary. I have to play a little bit with EKF params. Overall: Usable!
