Hi Team,

I've bought 2 voxl mini ecs, but both have issue spinning up a motor connected on port 0. It seems to be stuck in the synchronisation phase when motor ist jumping back and forth.
However the motor works fine on every other port. I also used the script to set params to the esc and the spin script to check. Also tested with different firmware versions of the voxl2-mini computer with no change.

Any idea what the issue could be ? 

Thanks in advance

Phil

@astro_phil can you please share a video of the issue and the esc params that you are using?

Thanks!
