Using the stock demonstration CSRMeshLight application:

I notice that the green LED illuminates brightly before AppInit is called by the CSR system.  This would imply that the port is being pulled low rather than floating.  Is there a way to define the state of PIO pins before the application code is called?

Are you running mesh on the CSRB534x hardware?  If not and you are using the CSRmesh Development Kit please use the relevant forum at https://developer.qualcomm.com/forums/hardware/bt/csr101x.
