Dear VTOLers and developers,
I have a strange problem with logging:
I'm using FlightPlot since ~1 year to analyse my flights, and so far it worked fine for me.
Default Logger was SDlog2, I never changed it before.
Currently I fly 2 vehicles, both in "Standard VTOL FunCub" configuration:
1. Vehicle1: VTOL-Plane: PX4 1.6.5, on 3DR-Pixhawk (like this http://www.robotshop.com/en/3dr-px4-pixhawk-advanced-autopilot-gps.html)
2. Vehicle2: a Copter: PX4 1.6.5, on Unmannedtech.uk Pixhawk (https://www.unmannedtechshop.co.uk/unmanned-pixhawk-autopilot-kit/)
The other components are 99% the same.
Vehicle2 works fine on 1.6.5, logger is SDlog2, logs *.px4log files, can be opened in FlightPlot. Perfect!
Vehicle1: Problems started after updating on 1.6.5 (flew on older version before).
Interestingly during update the Logger type changed itself to "Logger" (new). Noticed this after flying. The *.ulg logfiles worked in FlightPlot.
But I wanted to change back to SDlog2, because I have all my Plotting-Presets prepared for *.px4log files.
The *.px4log files are created during flight. But when I open them in Flightplot, I always get the error message "java.nio.BufferUnderFlowException".
Can't acces the logfiles.
I read somewhere about different flash sizes. Maybe the (older) 3DR-Pixhawk has less flash memory and can't run the current 1.6.5 firmware with SDlog2?
But the *.px4log is created, size looks normal. Just can't open it.
I'm thanks full for any advice!
