Testing – Triflight rebased on 3.2.2 Betaflight

[jihlein]

So if I understand things correctly,@me_tan’s board still does not want to boot, but @Kevin_Erik’s did. Curious to see what @krkljan’s results will be when he has time to test. The build is flyable, but I’ll make a branch with these changes and make an installer from that test branch for you guys to test with, before I merge these changes into my main branch. Do I need to make both Windows and MACOS?

@Kevin_Erik, there is no BiCopter mixer in the vehicle tab, it still needs to be setup via a custom configuration. That probably won’t change, at least in the foreseeable future.

Here’s the cleaned up version of the SPI fix. If this is proven successful, I will merge it into my mainline.

This build was successfully tested for booting on the RCE Racing and Integrated F3Fc boards I have.

@me_tan – there’s an additional change in this from what you originally tried, might be worthwhile to try this version

[Kevin_Erik]

Will try to load this up during the weekend. Unfortunately its hard to know when I’ll be free to do so due to the holidays.

I will also test with my spare board over the weekend and try the above suggestions

[ME-tan]

OK reverted the spare board back to TriFlight 0.5 to test it and it won’t boot on that either, so my boot loop is probably a hardware fault.

I tried to flash my newly rebuilt tricopter with a fresh FC on it, and it still doesn’t work though, so I’m probably doing something wrong. I’ll experiment with it a bit when i’m more awake

@jihlein
Tried to flash with latest firmware. It is not working for me. Still rebooting FC.

[jihlein]

Well unfortunately I’m about out of ideas here. Attached is a new firmware file that alters the SPI clock speed a little bit more. It still runs fine on my board here. I need to check other targets, but the RCE F3Fc Racing, RCE F3Fc Integrated, KakuteF4V2, and Matek405Ctr all work with this change, at least on my end here.

Attached is the new firmware file for the F3Fc, and 2 screen shots from my logic analyzer, showing the SPI clock during gyro init on both versions of the F3Fc. The clock is ~571 kHz actual reading, which is pretty much centered in the range specified in the MPU6000 datasheet.

Will try this tomorrow or aftertomorrow. Thx for all your efforts. Merry Christmass!!!

Tried last firmware. Now is not rebooting. But cannot connect.

Success!!!! Managed to connect!!!!!!!! Removed from Devices manager F3FC that had error and managed to connect………..

[krkljan]

News! After doing most of setting up to Davids video there is problem with motor outputs. Cannot get servo to work.

[jihlein]

@krkljan, hopefully it’s just a setup problem, as mine works. I’ve attached screenshots of the mixer setup and the output setup. I also attached the FC dump from my BabyTri. You could try loading that as a starting point, but be aware it’s from an F3Fc racing board, so will have to make orientations changes and other changes specific to your hardware.

Lastly – let’s move this discussion to the “dRonin for Tricopters!” as there are other users trying to get the F3Fc Integrated board up and running too.

Right, From Triflight 0.5, used the cleanflight configurator to flash the dRonin .hex file for f3fc from the post on 23rd December, using the dRonin GCS from the same build, used rescue button to flash the rescue file posted on 24th, I also erased the settings partition for good measure, am still getting this:

Anyone know where I’m going wrong here?

[jihlein]

Your not doing anything wrong from what I can see. I can’t understand why this board is so finicky wrt to the SPI clock frequency during init.
