Having the same issue with my JHEF7DUAL fc, was working fine and then flashed BF 4.5, BLHeli configurator reads from the esc via passthrough, but no spinning when trying to arm or use BF motor direction configurator

Same here.. FC BayacRC Dolphin.

And some errors with dshot600, with dshot300 - no errors.
And RPM filtering not working normal - create some resonance - without RPM filtering no problems..

Having similar issues with DShot 600 and 300 as well. I'm running a Tmotor VeloxF7SE. Flashed betaflight 4.5 on it and when I test motors erros on dshot telemetry appear, usually just in one motor. And it reacts when other motors are spinning. Flashed back t9 4.4 and it's fine not errors. Bug in Dshot??

which version of AM32 do you have installed on NeutronRC F435? Mine (35A version) works fine with 4.5 on AM32_NEUTRON_2_6S_AIO_F421_2.10.hex.

[error414]

I use ESC 1: NEUTRON - AM32, 2.0, Bootloader v1 (PB4), MCU: F421

[alexberdnik]

Can you try with 2.10 (available here: https://github.com/am32-firmware/AM32/releases/tag/v2.10) ?

Perhaps also try 4.5.1-dev (first)

[error414]

4.5.1-dev works
