adrv9026 CPU exception for any API call after initialization

Can you please share the detailed log? At what stage, are you running into this issue?

After running Madura init (using reference code) I use option "2" to shift RX2 Band A NCO1 frequency using function adi_adrv9025_RxNcoShifterSet function, and it generates an exception. Any other api call involving CPU results in the same thing. 

It looks like the initialisation is happening successfully. Are you facing this issue only you call RxNcoShifterSet API? Before calling this API, you were able to run other APIs such as Tx Attenuation change, setting LO frequency?

Have you updated the NCO configuration as instructed in this thread?

It's an issue with all APIs.
UPDATE: I placed the NCO shift function at various stages in initialization, and found that it works prior to  calling adi_adrv9025_TrackingCalsEnableSet function. The tracking Cals command is probably messing up something in the CPU, although it returns no error. I commented out that code for the time being and I can now call any API, such as LO frequency set, etc. during runtime.
