AD9375 DPD using SW v5.2.2

Category: Software
Product Number: AD9375
Software Version: 5.2.2

While testing DPD, we often get these issues:

  • There is no correction from DPD and DPD get irresponsive. When we want to check the status of the DPD by requesting mykonosDpdStatus_t, we get the error “mailbox busy”.  What are the reasons that can cause this error?  How to recover from this condition as even did reset doesn’t recover DPD? 

  • Sometimes running “dpd-reset” command appears to have no effect by observing the signal in spectrum analyser.  DPD status counters, for example dpdTrackCount, are not reset after we run “dpd-reset” command. Is there a way to reset the counters to be aware when dpd-reset takes effect.

  • Sometimes the DPD appears to enter error state during the initial ramp up of power.  Is there a way to avoid getting DPD to enter error state during the initial ramp up of power?
