As for SD Cards & formatting:
SD Card Formatter - SD Association -- this is the SD association’s tool that meets the true SD standard.
As for firmware, I did the upgrade, haven't flown yet. BUT redid IMU/Compass/Camera calibrations and noticed in the Windows GUI that pitch was 0.1 (roll & yaw were 0/0 solid), accel Z was -10xx (shouldn't it be around -9800?) and the GPS speed was static at 2m/s with 16 sats. Redid IMU cal, made sure it was level and pretty much same result. Moving it around, the #'s trended correctly, so I figured all I stated above are nominal values (A graph tool in the GUI would be helpful....). I did have to do camera cal twice as 1st time it centered 2deg off (noticeable).
As for GPS lock, I kept getting purple blinks (lost of lock) immediately after the upgrade on the bench, but once I calibrated all 3 components and connected to the GUI to verify the IMU data the purple blinks went away.
Lastly, I noticed at takeoff stage, the ST16 that G-SPD hovered around 0.1 kph, BUT showed 9.x kph for a fraction of a second (10ms?)... periodically. That's the disturbing part of this upgrade to me--anyone else seeing this? Just let the TH sit on the take off pad and look at the G-SPD.... Going to monitor this as I try out the new firmware
