Status LED Operation
This LED operates only at initial power up for a brief period. The LED is driven from GPIO23. Attempting to drive this GPIO from the test program fails as it is not exported to create the directory in /sys/class/gpio The QCA9558 Datasheet does not show any special function for this GPIO so it is not obvious why it fails the test program.
GPIO23 and the Status LED now operate correctly with updated firmware. Operation of Status LED requires software support.
Issue moved to Phase 2 testing to check software support.
