Hi All,
I made some changes to u-boot-1.1.5 atmel patch 1.5 and rebuild uboot.
However, after rebuilding it would not run uboot.
Has anyone had this problem before?
If I rewrite the dataflash with the pre-built uboot image, then it
boots so I guess I might be missing something. DataFlash is enabled
and all the options looks good so I'm not sure why it's stuct at the
RomBoot. I've rebuild both the dataflash bootstrap and uboot several
time with no luck so far. Does anyone have any ideas?
Thanks.

Makefile and config.mk files for my compiler. That's about it.
Oh, I also edited the display properties for my display.

No I did not. I don't have a reason to. Why?

On the 9263 it is 0x23F00000 and I believe I checked the bootstrap to
correspond to the same address. So, no not that config.mk file. Thanks
anyway.

Is the new size compatible with the armboot? Do you skip LOW_LEVEL_INIT?

Yes, it is skipped. From what I understood Bootstrap does the
necessary boot init tasks (althought I would rather put it in uboot).
Do I need to changs this?

No,

I will try to help you. Do you check the new size, format, etc... The 
new size fit in
you flash, do you write somenthing after the u-boot that overwrite it. 
Do you try to
load with a jtag in memory and execute it?

When you said new size, I take to mean the size of the binary images.
In that case boot the Bootstrap and uboot image size are smaller that
the prebuilt onces.
Bootstrap is written @ 0 and uboot @ 0x8000 (a 32K size). Bootstrap is
under 4K and uboot is under 185K. so I have lots of space.
The fact that I can rewrite my build uboot with the prebuilt uboot
image and this works ok leads me to believe their might be something
with the build that may be compiler related, but I'm not sure. Or,
it's something simple I'm missing.

I write my Bootstrap build @ 0 so that the only variable change is u-boot image.

I don't have a jtag fitted for this as yet.  I'm using the sam7 util.

Once I start using sam7 util, the bootstrap code has not been executed
which means the SDRAM has not been initialized. I'll have to added the
lowlevel init to do that, which I might try if nothing else works.

You don't understand:

- loady <address> u-boot-mod

I'm tying this method. I had to go to kermit because I never had
suscess loading serially with minicom.  I had problems with kermit in
the past but couldn't remember what it was... until now.  I've always
had fatal errors after a few bytes are transmitted. I get some error,
then it tries to resend but had too many errors. I'm not really sure
how to get past this as I'm configured the serial line accordingly.
Is this a common "user error" problem with ckermit? I've double
checked my config option with uboot docs.

I've narrowed down the problem to the compiler. I have several gcc3.4
and gcc4.1 based compilers and the gcc3.4 compiled u-boot binary worked.
I've been using the arm-gcc4.1-uclibc20061004 compiler with always
breaks because "uses hardware FP" whereas u-boot "uses software FP".
I've used arm-gcc3.4-uclibc0.9.28 compiler to build u-boot 1.2.0 which
worked.

I have used "minicom" a lot when downloading to the AT91RM9200,
but I use the special downloading program which I found somewhere
and included in the U-Boot-1.1.2 found on buildroot.uclibc.org.

Did you try programming from Windows using SAM-BA?

ckermit will work just fine and I rather stick to my linux system.
Linux can do everything windows does... and more.

It's a long time since I used minicom to load code on an AT91,
nowadays I'm using an ICE debugger (called PEEDI)
BTW the most common error was caused by 55 NAK errors and the upload 
failed. Maybe this hint can help, amybe not.

How large is the previous binary?

How much code does at91bootstrap copy to the SDRAM?

Look at board/at91sam9263ek/dataflash/at91sam9263ek.h for the definition of IMG_SIZE
I have 200 kB allocated.
#define IMG_SIZE   0x32000   /* Image Size in DataFlash    */

You need at least
#define IMG_SIZE 0x2E400
for 185 kB.

You will not be able to store U-Boot in the SDRAM until the SDRAM
has been initialized, so that is not an option.

Do  you use a dataflashcard?
It is easy to mix the chip selects.

Recompile the original source and see if you can run that.

Otherwise play with LEDs.
You can also try the SAM9263EK U-Boot-1.2.0 built by buildroot at "buildroot.uclibc.org".

That's correct.

That's the first thing I did. I originaly started with 1.2.0 then I
started with the original atmel_1.2 patch and later looked at 1.5
patch.

If you start u-boot that works the sdram it initialized so you can
using serial line of u-boot to load a code in memory and then
execute it.
