FC Freeze randomly in Inav 4.0.0 with JetiEXBUS

[RoadyFPV]

The FC Freezes randomly after a couple of minutes.

See here: https://github.com/iNavFlight/inav/issues/7434

[RoadyFPV]

Would it be possible for a developer to compile the current release version with GCC 9 for me?

[RoadyFPV]

After I have now tried a lot, I think I have found the issue why the FC freezes randomly.

It really seems to be with the ExBus protocol and the GCC10 compiler. Tests showed that the version with GCC9 compiler does not lead to any freezes. When I use INAV 4.1.0 rc1 with ExBus the FC freezes involuntarily.

Since the Jeti receivers can also output SBUS I switched to this protocol. The freezes are gone. Unfortunately, the telemetry then no longer works.

This is a realy dangerous bug and should be followed up.

@marv-t maybe u can assist here?

[RoadyFPV]

@stronnag is it possible that you compile me 4.1 release with gcc 9?

[stronnag]

no, I have no instances of old GCC.

[RoadyFPV]

seems like when i disable telemetry feature the bug is gone

[DzikuVx]

@RoadyFPV probably this fixes it https://github.com/iNavFlight/inav/pull/8024 I can not test thought

[RoadyFPV]

@DzikuVx Thanks, i will test it asap.

[RoadyFPV]

@DzikuVx I need a MATEKF722SE target to test it.

inav_5.0.0_MATEKF722SE.zip @RoadyFPV

[RoadyFPV]

Thank you, Is this only a test version or is It flyable.

[RoadyFPV]

Issue is still threre, fc freeze randomly

[RoadyFPV]

seems like if i set the transmit frequency from 100Hz to 50Hz the freezes are gone. More tests runnig

[ghost]

Hi RoadyFPV, did the 50Hz change really help?

[RoadyFPV]

Jea on inav i only have bench test.... for flight i wait for inav 6 release and use gcc9

Betaflight works without freezes on 50 hz

Thanks. When you have iNav 6 compiled with GCC 9 could you share it with me please? I would like to test it. I have something in mind. I do not understand these things. What is actually compiled? Is it a .hex file or something else?

[RoadyFPV]

I am trying my best. Please remind me if I forget

[RoadyFPV]

Wich Target do you need?
