Hope everyone are doing well..
We have a board with RFSoC XCZU49DR with PS DDR 4GB
We are facing an issue with PS DDR Initialization, The following address returns this:
Address: 0xFD080030 returns: 80C000FF
Which as per this register map: Zynq UltraScale+ Devices Register Reference
it is some Deskew done of read and write/ Eye training done error is showing.
We have measured all the DDR Voltage and CLK seems to be fine. Is out of reset.

We have tried reflow of DDR
We have tried reflow of FPGA
We have replaced the DDR, below are the observation after replacing the DDR, Still the same, Address 0xFD080030 returns different value of 808000FF
DDR part: MT40A1G16RC-062E IT:B (Micron)
Any suggestions would be appreciated. Thanks.
