AD9361 NoOS code with external LO

I am trying to use the AD9361 No-OS code with an external local oscillator on a custom PCB.  Everything works fine when I use the internal synthesizers but as soon as I switch to the external LO, the ENSM state machine does not transition out of state 5 to either FDD, TX or RX modes (depending on whether I am using  using both TDD and FDD modes). What parameters in the initialization structure would I need to change to go from an internal to external oscillator ? If I am using an external oscillator is it important that the rx_synthesizer_frequency_hz  parameter is set to the external LO frequency ? Also do I need to change the rx_path_clock_frequencies[6] parameters ?
