AM5706: Power up sequence waveform in AM570x 6-Layer PCB Reference Design

Hello,

Do you have an actual waveform data for power up sequence in AM570x 6-Layer PCB Reference Design?
My client designed a proto board basically followed this reference design and see some unexpected power up behavior, so he'd like to confirm if it is an acceptable or not for AM5706 design requirement.
The expected sequence is as follows. (from SLVUB99A)

Thanks in advance.
