 The Mosiac-X5 NRST_IN# needs to be floating (internal pu) or driven high at 3.3V to allow the card out of reset.

+The standard GW16160 uses M.2 Pin 65 (W_DISABLE1#) as the source of this reset.

 Reset Loading Options:
+ - M.2 Pin 65 W_DISALBE1# (default for GW16160-B+) via R25
  - Resistor R20 can be loaded and U7 unloaded to directly connect these if used in a socket where this pin is 3.3V
  - U7 can be unloaded and the internal PU will allow the Mosiac out of reset without the ability to reset it via hardware
