We are using CSR SDK 3.1.1 and building the CSR102x Quadrature Decoder example application.

It builds and runs perfectly on the Professional Development Kit board with the CSR1025_A05.

However, when we try to run the example on our own PCBs with CSR1025_A06 devices, we are running into issues. The application builds and runs sucessfully, but the 8051 code does not seem to run correctly (the quadrature encoder emulator output is not functioning correctly).

We instrumented these outputs with an oscilloscope and they stay HIGH instead of oscillating like they do with the Development Kit and A05 device.

Looking for help -- is there something that needs to be done differently to exercize the 8051 on A06 devices?
