CC3220MOD: Extrem high current from NWP of the module

Hi, 

I’d like to do a consult about the CC3220MODSF module NPW current consumption: 

1. During a manufacturing process, we have found several defected CC3220MODSF module.
2. The result is indicated as following, when the NWP is enabled on these devices a very current peak is detected and produce the restarts of the device (see the attached graphic):
3. The 3.3V on board still keeps high, around 3V, so the brownout should not produce; but the device is restarted all the times (see the attached graphic).
4. I have checked its UART output, the device stops when the NWP is enabled.

For us it is interesting to know:

1. Could you recommend any way to check the NWP to make sure it is broken or still can be used? AT-command is useful for this check?
2. On which part of the HW shall we check to determine the origin of these high currents? Because it occurs in > 16% of our manufactured devices.
3. During the manufacturing process, we have used a resin/epoxy to protect the device (wrap the whole module), will it damage the CC3220MODSF?

 Thanks and regards,
