I uploaded the new ArduPlane 4.0.1 firmware to my Pixhawk 4 and tried to fly some Auto-WP missions to create some orthophotos.
I have the problem that the camera feedback trigger via hotshoe does not work properly. So I did some trials with the camera hooked up on the bench. I armed plane and then took about 18 pictures with the “Trigger camera NOW” command.
After downloading the logfile I tried to use the geo ref images tool and loaded the correct log and photos. When I choose Trigger Message as source it shows less trigger messages than actual picures taken.
Before the fw upgrade I used ArduPlane 3.9.7 and it worked fine (at least I did two missions with roughly 1800 pictures each and it worked perfectly!). So I tried to downgrade to 3.9.7 again. Thing is that no log is created in the earlier fw versions anymore. I checked the “LOG_BACKEND_TYPE” and its set to 1 and the bitmask is 65535. @tridge: What could cause that problem?
