Hey
not sure this is known already, the upload of the parameters with MP can become extremely slow.I think I've read in the issues or PR, and also in the mai-01-Dev report about a parameter upload problem, but these reports I understood to mean upload in flight. Also, it read to me as if the problem there was solved. So, to be sure, I've flashed the latest AP3.6-dev v2 of tonight, as well as the latest MP (not beta, official).
I've made a short video, since I considered this faster than trying to explain that here: https://www.youtube.com/watch?v=tqslbQcylE0
I had that problem also with the previous 3.6-dev I had flashed (ca. 2-3 weeks old), but not with previous versions. The behavior is reproducible.
I'd like to mention that with UAVCAN enabled and with uc4h UAVCAN nodes connected, I can get all sorts of instable behavior, the ardupilot node having sometimes problems to appear, suddenly appear&reappearings, the 2nd set of tones to very late, extreme slow downs and complete hang-ups of MP at parameter upload, and in one case even a crash of MP upon trying a connect ... however, I could not see the systematics so far, nor is it reproducible but just happens more often or not, all this looks connected to me, but that's not actually clear. So, I just mention this set of issues here, but currently feel unable to provide more helpful info.
Thx,
Olli
