[KS1][Resources] Resources state to enter into KS1?

We are having problems entering into KS1 state and I would appreciate your support on the next questions:

1) With the SCU firmware compiled for debug, I can use the power.r command that displays a set of resources which are either "on" or "lp". So, the question is: how should this report from "power.r" should look like after A35 is in "Suspend mode" and M4 is in "VLLS mode", to make sure the iMX8 can enter into KS1?

2) Is it possible (or valid) to try to enter into KS1 with the Lauterbach connected to the M4?

3) Is it possible (or valid) to try to enter into KS1 if the Lauterbach is disconnected from the M4 after VLLS state is requested?

Thanks in advance for your support.
