On my target board after PoR the iMX53x DDR2 interface is not working.
The transfer of OS image on NOR to DDR2 is having an issue.
The CKE after PoR is always low whereas NOR bus activity shows up for few seconds and then halts.
System never boots. I am suspecting the iMX boot ROM code which initializes the DDR/NOR interface for OS transfer.
The board is production grade and was working fine before as intended.
Please share your views on how to confirm the issue.
