Failed to use EVSPIN32G4-dual with MCSDK6.2 to control dual 3-phase BLDC with FOC/Hall

Hello,

I'd to drive two 3-phase BLDC with FOC & Hall on EVSPIN32G4-dual board, generated the code from MCSDK6.2 (support dual motor control).

First, I control the M1 motor only, it's well, then stop the M1 and control the M2, it's also well.

But when I control the M1 first and then wait for seconds to control the M2, the M1 and M2 both are unstable & vibrating. 

Measure the PWM signal from gate driver STDRIVE101, found the PWM signal is anomaly.

I cannot figure out the reason, is it caused by concurrent FOC or some else?

Can someone give some advice, thanks.
