Hey Guys,

I've been troubleshooting my Flight Controller (FC) in BetaFlight the last few hours.  Need a little help as I'm a little new to FPV setups and BetaFlight.  I'm not seeing any UARTs in the PORTS section (PIC 2) of Betaflight and the "Calibrate Accelerometer" is greyed out on the main screen (PIC 1).

PIC 3 is just a screen shot of "what I should be seeing" from a working Flight Controller Screen Shot (I added just for reference).  PIC 2 is what I'm seeing in BetaFlight with my Flight Controller.  No UARTS showing at all.


I've re-flashed the firmware but that didn't help and I've replaced my ribbon cable between my ESC and FC (I know the ribbon cable is fine).  Any thoughts....Is this a damaged Flight Controller?   Also, I'm seeing 1 solid Green LED on the FC and 1 solid RED LED on the FC, but not sure if that's normal or is telling me something.

With no UARTS my FC can'ts see my Remote Controller....if it's a bad FC I'll order a new one.  Thought I would check with some experienced folks on here first.  It's a HobbyWing Flight Controller.  


P.S.  I've tried reflashing the firmware a few times hoping that might help but did not.

Just some thoughts-

Did you flash the correct betaflight target for hobbywing?

Do you have the latest betaflight configurator version?

Yes, I did a full backup in BetaFlight when everything was working.   Cut/Paste below:

# version
# Betaflight / STM32F405 (S405) 4.1.1 Nov 15 2019 / 12:54:53 (1e5e3d369) MSP API: 1.42
# manufacturer_id: AIRB   board_name: OMNIBUSF4SD   custom defaults: YES

So, I did download the "STM32F405" newer version (and even reflashed back to the 4.1.1. version but nothing.  

Yes, also using the newest version 10.6.0

WHAT TYPE IS HobbyWing FC ?

Sorry, I may have mis-spoken (typed).  The build I received is the Rotor Riot HD1 Build.  Here's the actual link.  I didn't build it myself so it's hard to know the exact make/model flight controller because it was put together by Rotor Riot.

However, I did a "VERSION" command in BetaFlight CLI (when I first received the quad) and here's the output.

-----------------------Start of Cut/Paste------------------------
#

# diff all

# version
# Betaflight / STM32F405 (S405) 4.1.1 Nov 15 2019 / 12:54:53 (1e5e3d369) MSP API: 1.42
# manufacturer_id: AIRB   board_name: OMNIBUSF4SD   custom defaults: YES

-----------------------End of Cut/Paste----------------

You can see it's "STM32F405 (S405)' FIRMWARE on this Flight Controller (FC) so that's what I flashed onto it.

I just ordered a new Flight Controller and I see it's a different firmware version.  Sorry for the confusion.

Please get in contact with Rotor Riot to let them know you are having these issues. They will be able to help you as they built the quad. I would advise against replacing components as you will void your warranty.

Thanks...yes, I'm shooting them off an email now.  I've emailed them before there usually very responsive.

I'm just realizing when I did a "VERSION" in Betaflight before updating the firmware here's what I got.

# version
# Betaflight / STM32F405 (S405) 4.1.1 Nov 15 2019 / 12:54:53 (1e5e3d369) MSP API: 1.42
# manufacturer_id: AIRB   board_name: OMNIBUSF4SD   custom defaults: YES

QUESTION:  I downloaded "STM32F405" as shown on the first line....BUT, was I suppose to download what's on the second line instead "OMNIBUSF4SD".......     .... Now, I'm questioning which line I was suppose to be looking at.

flash again
choose Firmware: OMINIBUSF4SD (airb)

Yep, that's what I'm doing when I get home today (currently at office).  I followed Joshua Bardwell's video but I think your 100% right....Will let you know what happens since you've been helping me.  

P.S.  Oh, and did email Rotor Riot this morning as well (curious to see what they have to say as well).

My response from Rotor Riot...cut/paste below:

---------------------------------------------------
Hello!

Thanks for reaching out. We don't recommend that settings like this are modified unless fluent with the systems as it can make getting back in the air difficult. The best we could do is send over a CLI dump with our original settings on them. The target will be the "Omnibusf4sd" when selecting firmware. Let me know if we can send over that cli, we will be happy to help!

Rotor Riot
---------------------------------------------------------------
So, I'll be flashing Omnibusf4sd when I get home..fingers crossed!

*UPDATE* - I also posted this question to Joshua Bardwell (I'm sure many of you guys know him).  This was the response; "....You want OMNIBUSF4SD. The version command changed in 4.1 because of the move to Unified Targets.".

Thought I would post in case anyone else runs into this.  Looks like I didn't need to purchase a new flight controller after all.  On the positive side, I guess I'll have a spare should I need it.

That was it....Flashed to Firmware: OMINIBUSF4SD (airb) and we're good now!   

Thanks for the help...

I love you man
I had the same issue
Followed Joshua's tutorial. He said to flash it according to the number is says here;
# version
# Betaflight / STM32F405 (S405) 4.2.9 Apr 27 2021 / 19:33:01 (e097f4ab7) MSP API: 1.43

The STM number is what it says to flash at!

Not sure if theyve changed it but yeh that tutorial is a bit out of date I guess
I flashed it to betaflght4 which is what it says after
Boardname and it looks happy now

Glad it helped!  That's why I posted it here...figured if I had the issue others may run into it as well.
