I've just upgraded my X8 to Copter 3.5 RC8.
The first flight was uneventful, just a bit of additional Alt-hold oscilation, however the second flight triggered an EKF failsafe, and by the looks of it all the devices connected via i2c stopped providing data.
On i2c I have connected Optical Flow, Lightware SF11/C, Compass and LED.
(previously, SF11/C was connected via serial, but I wanted to free up the serial port for a 2nd GPS)I've checked the wiring and nothing seems to have come loose.
I'm thinking either I've overloaded the 5v supply on the i2c port (although all these devices together use <500mA)..... or there's still a problem with running Lightware devices on i2c.
On a separate note, I Optical Flow doesn't seem to stay enabled after power cycling some times. (I had double checked it was enabled before this flight, but the log shows it was disabled again).
