PDM support with A2B bus analyzer

Category: Hardware
Product Number: a2b bus ana

Hey,

I recently got one of the a2b bus analyzer and am trying to emulate ad2427 on it. 

Background: We have a chain of mics that are currently running with ad2428 as a main node and ad2427 as downstream microphones connected on PDM0 sending data upstream.

Modification: Replaced the downstream bus node closest to the host node with the ADI a2b bus analyzer and am trying to emulate it while also feeding in different tones.

Issue: 

  1. As soon as discovery is complete I see the following error/warning pop up on screen.
  2. My stream is set up so that each node adds 1 to upstream slots to put it's own mic data. 
    1. This is evident with the slot config
       
    2. But when i go into the audio tab I do not see a source stream available to emulate sending any audio.

Could you help me figure out if I'm doing something wrong or if this is even supported ? All other streams still work fine and the entire setup without the bus analyzer and just the mics also functions properly.
