Hi again,

Last week I asked for advice on getting an FMC slot working on a ZCU102.
I think I have the FMC slot on my board at least partially working, and I've been running the "fmcomms_2_3_rx_test" and "fmcomms_2_3_tx_test" apps to try it out.

Both tests run until they get to the first test in the "test_app_rx_value_corruption.h" file, where it tries to set rx_rf_gain_db.
I'm getting the error message:

invalid gain 72, supported range [-3 - 71]
Unable to write gain tbl idx reg: 268
Exception thrown: AD9361_config_proxy produced error during execution: ad9361_set_rx_rf_gain() returned -22.

Any suggestions as to where I should go from here?
I should mention although I have the FMCOMMS card plugged into my board, I currently lack the capacity to provide it a source (i.e. the actual rf ports aren't attached to anything).
Could this be my problem?

Thank you for any advice you have,
