Holybro Kakute H7 (stack) on 4.5 gives me a "motor_protocol"error

[x8n1620]

Describe the bug

Same as betaflight/betaflight-configurator#3768, but with other FC Motor protocol error in 4.5 using dshot600 on a Holybro Kakute Stack (H7 FC and Holybro Tekko ESC) I also try

• dshot 300 or dshot150
• disable bidirectional dshot
• try it with bf-defaults, only aux and serial applied

I can spin the Motors from the Motor-Tab in BF. But arming is still not possible

Reflashed down to 4.4 and the quad works fine. Flashing 4.5 again, same problem

edit: The solution for me was:

• Remove "Dashboard" from the build
• enable bidirectional DShot
• CLI: set dshot_bitbang = AUTO

To Reproduce

Flash a Kakute H7 Stack to BF 4.5

Expected behavior

Arming Possible

Flashing again with Target: KAKUTEH7 Version 4.5.0 [28-Apr-2024] Full Chip erease

When not using Dshot telemetry try set dshot_bitbang = OFF

[x8n1620]

After setting set dshot_bitbang = OFF -> arming possible, Motors spin up

edit: sorry, arming is only possible, when I check the "Motor Test Mode" in BF. Without USB-Connection still no arming.

edit2: After setting back dshot_bitbang to AUTO -> no arming, even with "Motor Test Mode" in BF.

[haslinghuis]

What firmware is the ESC running?

[x8n1620]

At first 32.08, after having trouble to arm I update yesterday to the newest version 32.10

[haslinghuis]

Using 32.8 here without problems. 32.10 did not work for me. 32.7 is still the recommended version:

https://betaflight.com/docs/wiki/getting-started/hardware/esc-firmware#blheli_32

[x8n1620]

With the blheli suite I can rollback to 32.8. I have no option for 32.7

Anyway, after done this, the quad arms when I set dshot_bitbang = OFF Heureka!

With dshot_bitbang = AUTO still no arming possible What does this mean for my quad?

[haslinghuis]

Take a look at https://github.com/betaflight/betaflight/pull/7446

[x8n1620]

I did not understand a single word of what was said in #7446 But i will configure my quad and try (tomorrow).

Thanks for your patience and support!

[x8n1620]

Can't get my quad running with BF 4.5 After reflashing 4.5 with all of my Options (AcroTrainer, BattContinue, Dashboard, GPS, OSD (SD), OSD (HD) and fully reconfigure it, it won't arm again. :-(

A Diff All of my configuration is attached.

• Now with Dshot telemetry enabled use set dshot_bitbang = AUTO instead.
• Remove Dashboard if not using an external [O]LED display.

[x8n1620]

Oh man, w/o Dashboard and with set dshot_bitbang = AUTO I can finaly arm my quad Honors to @haslinghuis :1st_place_medal: Flown a short round in my pitchblack Backyard -> it's working.

[Strangedave]

It seems that there is a missing custome default setup, the OSD chip is not working either. I was able to load 4.4 do a dump all, apply the dump to 4.5 and now its working

[haslinghuis]

@Strangedave remove OSD_HD from the build.

[Strangedave]

I am still analog on that rig. maybe it will get an upgrade, but probably not. Not a real reason to go digital on a marmotte.

[Strangedave]

I Gottcha. Didn't understand what you were suggesting initially. Hoping not to mess with this rig for a minute. Will try and remember for next time.
