Hi ,

In U61002E,PC_07 is floating.
>>As per the designer quick manual "Defaults to SYS_FAULT on LPC package, so external pull-down required to keep signal in deasserted state"
So we suggest you to add external pull resistor on PC_07.

We suggest you to refer ADSP-2159x DESIGNER QUICK REFERENCE (Page No:59/145) from the datasheet and please confirm whether you have designed based on that signals termination recommendation.

In U61004,SO/IO1.
>>As per the schematic, we suggest you to add external pull resistor on SO/IO1. We recommend you to refer the ADSP-2159x schematic (Page No:8/13) from the below link.
