We have a FMCOMMS5-EBZ board and we have made it work on a ZC706 carrier board. So far, signals of the 4 Rx channels from the two AD9361 devices can be captured and viewed on the IIO Oscilloscope. Calibration can be done successfully. However, the channels are not in-sync. When the MCS_Sync tab is pressed, the phases of the Rx signals do not change. When we monitor the SYNC_IN test point on the board with a scope, we cannot see SYNC_IN pulses being generated when we press the MCS_Sync tab. Could you please give advice?
