controlling Two F28379D simultaneously

Hi there,

In my project, I want to control two motors, one is the load motor and the other is MUT. I used two F28379D launchpads with two three-phase inverter. The first motor connected to the first inverter that controlled by first launchpad, and the other motor connected in the same way. The DC link, and axuiliuary supply are shared between them. The ground is connected between all of them. However, when I control the first motor (load), the ADCs for the other launchpad get lots of noises. I am not sure, whether, all these two launchpad should be supplied individualy or they have to communicate with each other. Could you please help in this matter.
