You are indeed making PHYs as sub nodes to the top CAMSS and not independent nodes like CCI.Just looked at your DTS series and realized. I will let the discussion about enumerating TOP resources in every child node continue in the other thread. Thanks.>> --- >> bod > Thanks, > Vijay. Thanks, Vijay.
