MATEK H743 freeze after couple of minutes with INAV8 + JETI #10646
Comments

Can you please include a settings DIFF, not a DUMP. When you said it freezes after a couple of minutes. Is that after the same elapsed time in each test ? |
|
Diff: https://pastebin.com/Nm0Syd10 It freeze with Battery only It freeze without sd card and enabled bblog |
|
I see you are using Jeti, which you have reported elsewhere is locking up again. Don't you think that could also be the problem here? |
|
i dont know. |
|
Have you tried setting serial RX to something like CRSF and physically removing the Jeti receiver? |
|
I will try it and set rx to sbus i noticed something strange right now, but i cant say exactly if it was before the freeze or after. |
|
Seems like no freeze with SBUS |
|
So it seems like another Jeti related issue to me. |
|
can u compile me inav 8 with inav 7 compiler? lets see if this fix the issue like in inav 4 |

Try to test with the artifacts from #10653 No guarantees, so test in the bench first. |
|
Thanks, test is running... What i also noticed some time ago, i have 16 channels but inav shows 24 channels on reciver tab. Here is a video with 16 channel mode |
|
It freeze around 7 min |
|
This will likely be a tough one to crack without hardware. |
|
Jea i think so.. i have a suspicion what it could be, but unfortunately i don't have the programming skills to implement it. in the beginning with jeti, between rx and tx, i think it was a 2,4k resistor was needed. then marv-t in betafligh implemented it in the code so that no resistor is needed anymore. maybe go back with the code so that the resistor is needed and test it? if i can remember correctly from testing in the past, if i disable telemetry feature it dont freeze |
|
I reached out to JETI to see if they are willing to provide a test system on loan, or if they have some sort of simulator we can use. Otherwise, we may have to depend on someone in the community donating a radio + rx for testing. (It does not need to be the latest model, so if you anyone has an older JETI system that is compatible with EXBUS and is willing to donate to the INAV team, reach out!) |
|
Great, thank you. I'm curious what answers now, don't think they'll go into it. I might have a transmitter and rx available on loan, if jeti dosent respond. May I contact you on discord? |
Sure, but I would wait for Jeti to reply. I have no idea how long I would need the radio for, so I would rather know I am not preventing anyone from flying in the mean time :) |
|
Meanwhile as I also have some JETI planes with INAV (using Jeti's exbus protocol) I could test out Inav 8 on some FCs. So what do I exactly need to do to cross check with you guys? |
|
I have right now flashd inav 8 on ma matekf722 wing. lets see what happens. @jaroszmm maybe its a combination of jeti protocol an the other connected hardware |
|
@jaroszmm |
|
ok, freeze too with f722 with only rx connected after around 20 min From my testing some time ago i noticed that the freez maybe takes longer if i use 50Hz transmitter rate. |
|
Hello, I have the exact same issue with h743 and jeti on fixed wing, exactly the same as we had before somewhere in 6 or version 7. |
|
@JWC1304 Can you pls try to disable the telemetry option in INAV configurator and look if it freeze? |
if you use a matek controller and inav8 it will freeze after a few minutes of flying. the last time it was something with exbus jeti with made it freeze, basiccally losing signal. |
i would like toi but than i will have to sacrifice another plane or bird, i can only repeat it while actually flying. Or can you tell me how to test this on the bench |
No, it freeze on bench too with usb. pls confirm first the freeze with telemetry enabled and usb. |
okay give me an hour (dinner in between )and i will report back asap |
|
It's probably worth adding Jeti causes freezes in the known issues of the release notes. |
|
@MrD-RC Sounds reasonable, protects other user from lost her plane. My test without telemetry runs for 2h15min now without a freeze and still running |
|
I think it could be a problem with the one wire communication misstiming or somewhat. maybe we can try the old jeti exbus and telemetry code from the beginning. https://github.com/betaflight/betaflight/blob/v3.3.3/src/main/rx/jetiexbus.c after that, the code was changed so there is no resistor needed and connect directly to tx pin. |
|
3h and no freeze. i will test tomorrow again |
|
just to be sure mine is running now without ceasing and telemetry off in the configuration tab right? Will also try But assuming it is a quick fix turning off telemetry, but can this not be resolved like the last time this happened? The freeze combi jeti and matek? |
|
try first to reproduce the freeze with telemetry. arming is not required. |
ok WILCO |
|
I think we are on the right way to find the issue on the telemetry side. |
|
are you sure not arming? , because on the bench now for 6 minutes with telemetry and not freezing up, while in flight it is before the 5 minutes mark. ( i do not have gps lock, makes that a diffrencer because i am inside not near a window) Did change it to horizon now instead of manual, maybe that makes a diffrence? |
|
freeze is totaly random sometimes 20 min or 4min or 1h10min |
|
My setup for testing is matek f722 wing with only rx connected and a matek h743 with gps and dji vtx in a plane |
testing with matek h743, jeti transmitter, and trying to get gps now and arm and kmeep testing till it freezes. |
|
Yep it froze !! After 10 minutes, Call me nuts, but with me it is every time i am playing with throttle while armed ,it freezes, loses signal, etc. wil try to repeat this now without telemetry. |
|
Okay so far 10 minutes in without telemetry and gps and so far playing with throttle like a fool, but all systems seem to keep working and stable. Will keep on going for another 10 minutes if you do n ot hear back, assume it is working without telemetry. update no freeze so far half an hour without telemetry |
Sorry, not yet. Been busy with other stuff but might find some time today evening. |
|
Well i can confirm again without Telemetry i can not induce a freeze, within the 40 minute mark, i stopped than. Tried to induce it again with telemetry, on usb, without usb connected, disarmed, armed, with low throttle, etc. It seems it freezes up only when i give max (when armed) throttle and than lower it again and than full again, those are the moments it freezes within minutes.(with telemetry) Without telemetry i can not make it freeze at all. (gps ios still connected btw) If I remember correctly this was the exact same error as in a previous (version 6.X or 7.0 i do not remember exactly) and same behaviour. Let me know of i can be of further assistance |
|
Yes, looks like the same issue wich comes out with the channge from gcc9 to gcc10. This Issue is a real ghost. It comes and goes..... |
for me there is definitely a correlation when armed and playing with my throttle over 50%, i do not get it,but that is when i can induce a freeze in minutes, whille sitting on the bench,armed and at low constant throttle it seems stable, very strange (needless to say this is with tlelemetry). |
|
another 3h test run without telemetry and no freeze. yes, i tried out wiggeling the throttle stick with telemetry enabled and it freeze much faster. you are right. I think that the different packages collide with each other (telemetry request and the channel data) so that it leads to freezing when switching the rx/tx functions. all just a guess, i can't confirm it. |

Hi everyone, this problem seems to be exactly the same like when version 6 was released and new version of compiler was used. MATEK H743 was working properly only when telemetry was off or when INAV was compiled on version 9.3.1. I still use INAV 6 compiled on 9.3.1. and it works without any problems till now. I was very critical to developers at that time and was banned for my hot comments. History repeats itself but this time one of the devs is willing to take Jeti HW into his hands and try to correct the issue. I am glad to see such a progress and hope for Jeti users to see a light at the end of the tunnel. |
|
@robertbulko @JWC1304 can you guys test this file with telemetry pls? Only for Benchtest |
|
I am sorry, I won't do it. I have no spare H743 board for testing and do not want to disassemble the one I have in the plane. I'm happy it is working. (I mean using version 6.0 compiled on v9.3.1) |
|
will try later today ! |

(I mean using version 6.0 compiled on v9.3.1) you do not need to offer it up just reverse to your old settings and or version after testing |
I did it before and I consider it useless unless some of devs really has JETI HW for testing. In my opinion, this kind of testing proves really nothing relevant. |
That type of you dont realy help. Its better u will banned again. |
Whatever, I am not willing to do the same thing and wait for different result. It is not very smart. As I said, the only relevant way to make a progress in my opinion is developer having the JETI HW. Until that time it is useless. |
|
2 test done with modified code. 1h30min no freeze with telemetry enabled Telemetry looks clear without any gaps in the record |
I flashd INAV 8 to my MATEK H743
after a couple of minutes the FC frezze no Servo and configurator reaction, only a usb reconnect or disconnect the battery will help.
With INAV 7 no issues at all.
Steps to Reproduce
1.Flash INAV 8
2.apply the modified diff / or set it up new
3.The FC freeze after a couple of minutes
Expected behavior
It should not freeze like in INAV 7Suggested solution(s)
Find with me a way to clear the issue, maybe u can give me instructions how to find itAdditional context
