Dear Scott Wood,
1. Board Bring Up(u-boot and kernel) in Nand Flash With the setting of cpu = 533MHz,ddr = 533MHz and lbc = 66.66MHz. we can able to make u-boot up and kernel with all drivers modules are up and prompt is appeared.
2. Board Bring Up(u-boot and kernel) in Nor Flash With the setting of cpu = 533MHz,ddr = 533MHz and lbc = 16.66MHz. we can able to make u-boot up and kernel is not up. i.e, the drivers in kernel are unevenly initialized and getting into kernel panic state. I have attached the file that shows above mentioned behavio1 please find the attachments.
If the cpu frequency is reduced to 266Mhz and DDR with 533.33MHz. kernel initialize further but result is same as above(kernel panic).
NOTE: we have observed that if same kernel image is put in the Reference Design Board(P1021RDB-PC) it is working fine.
From u-boot we have tried changing OR & BR values along with LAW and
TLB values..Are we missing something??
As our Deveopment is stuck please reply ASAP

Please reply ASAP.
I believe the remarks above won't help you, neither will top-posting.
The problem looks to be either DRAM setup being incorrect or kernel problem.

Dear Marek Vasut,
The same kernel image works fine in P1020 RDB board with NOR flash boot.
When the same kernel image is used for our custom board with P1012 processor we are getting kernel panic.
We are also suspecting on memory, How do we trace it ?
Note: The same kernel image is used for our custom board with P1012 processor with NAND flash boot & its also working fine.
