DS90UB948-Q1: LINK issues

Part Number: DS90UB948-Q1

Tool/software:

Hello team,

My customer met some link issues when debugging 947+948, it is dual port STP connection from host to display, it is configured as automatically identification in 947 and 948 registers, the link ready status is found as single link ok. If configure the host side as dual link, it is reported as no ready.

Pls help analyze it, thanks!

BR,

Daniel
