Hi,
I am trying to initialize the DDR3 present on my board, using the u-boot
with DMA engine on my board.
My board is mounted on linux machine.
DDR3 initialization completes successfully after warm boot (given init 6
command on linux).
But the same u-boot code fails after cold boot (given
Hi All,
Can I expect a reply from seniors who might have faced this kind of issue?
If anyone have faced this kind of issue earlier. Please reply.
Thanks in advance.

Hi,
I am using u-boot as Bootloader for my PPC440 core based hardware board.
I am trying to run the u-boot code from Context RAM (Size 4 MB) instead of
DDR and I am successful in it.
But I am observing a machine check exception error while doing board hard
reset (by pressing the reset key

Hi All,
I am facing an error while porting u-boot for my platform because if

After running the u-boot to detect the DDR and flash u-boot hangs after
showing the serial console output. In debugger I am seeing PC at 0x0400
address which the exception handler vector address.

I am using an utilty to erase flash and to load uboot image and it is
working fine, only that it copies data at multple locations.

Hi All,
I did it. :)
I am now able to detect the flash. So now I can run the uboot commnads i.e
flinfo to check the flash information.
For this I make use of ST fixup code for M29W128GH in which I changed the
codition for chekcing chipwidth.
To detect the flash I used chipwidth 16 Bits and Port
now that you use a bigger FLASH chip.
Does uboot support one single TLB entry for 64MB size. At pesent I have
configured 4 TLB entries, each 16MB.

Hi,
In U-boot I am not seeing the support for Spansion S29GL512P NOR flash.
This chip is CFI compliant so I believe the common CFI driver should work
with this chip.
Does U-boot supports S29GL512P NOR flash or I have to implement the
functionality to support S29GL512P?
If anyone has tried with

In October 09 month, I had asked whether U-boot supports M29W128GH, a CFI

So I have used Uboot for my PPC440 based board.
When I flashed U-boot

Is it fault in start.S or somewhere else in code I need to see?
It would be great if someone who already have a solution on this
porblem, share his experience.
