I see a difference in my PixRacer behavior when I power-on my copter by connecting battery.
If I turn on my RC first, then connect battery to a copter then everything works without a problem.
But if I power-on my copter without having RC enabled then following issues noticed:
- MissionPlanner retrieves parameters very slowly (like 1 parameter at 1-2 seconds)
- OSD (Telem1) does not work (“No Data” message from minimOSD)
It looks like firmware is generally working, but some task takes a big CPU time. And mavlink transmittion rates is wery low.
If I then turn on my RC - firmware stops freezing (MissionPlanner can read and write parameters as usually). But OSD (Telem1 port) still not working slow.
Also after RC is enabled, FC buzzed beeps a single tone. I don’t know what it means but normally (when RC is enabled first) there is no such tone.
