Yes. master does not work still. v1.9.2 works fine. I scoped the motor outputs during boot and I am seeing some differences.
v1.9.2
master
As you can see, there are 5 pulses of 900us pulse width spaced at 20ms on v1.9.2, they do not appear on master. I have no idea if these pulses mean anything to an ESC, this is the only difference I was able to find. During flashing of firmware, the PWM stays at 900us and 400hz during the entire flashing process for both firmware versions. It would be good to get someone to work on this, as I currently cannot fly master on my development platform, which is severely limiting me
