[U-Boot] sam9x5 can't find Nand flash

[alex]

 Hi MAINTAINER:
  Now I develop our product based on sam9x25 EVK, and redefine our NAND partitions. I set u-boot environment in flash address0x80000.
if "saveenv" and "reset", u-boot will print "can't find NAND flash". If I set u-boot environment in the address 0xc0000 as EVK board, it's OK. I cant' know the reason.

Best Regards,
Alex

Which u-boot version do you use? Please also paste the u-boot boot log here.

Please also check the u-boot file size, will the env overlap with it?

You should also provide bootstrap log info.

I think the code is get from www.at91.com/linux4sam.

Anyway, I assume that you use the source code and package get for the 
upper website. If so, the u-boot environment you change is overlap with 
u-boot. (If you write the u-boot at offset 0x40000, the size is larger 
than 256K, that means: u-boot offset + u-boot size > 0x80000). So, when 
save environment, it will overwrite the u-boot, which cause this issue.

Please check it again. If all thing as I guess, you can change the 
u-boot offset to 0x20000, or change environment offset to 0xa0000. you 
can choose which you prefer.

Bo Shen

Hi:
  Thanks, it can work now. BTW,  one question whether the atmel' patch on v2010.6  is merged int u-boot mainline?

if you provide a rebased version on current HEAD we will do so.

The mainline for at91sam9x5ek is supported. You can find it on tag 
2012.10 and after.

But, one thing should keep in mind, it only supports mainline Linux 
kernel for at91sam9x5ek.

What's your mean about this? What Alex ask has been merged into mainline.
His issue is that he change the offset of the u-boot environment cause 
the overlap with u-boot.

Can you tell me from which tag on mainline kernel can work with mainline u-boot?

When the mainline kernel support at91sam9x5ek, it can work with mainline 
u-boot. You can choose the kernel version as you prefer.

Btw, this is u-boot ML. If you want to know much more about the Linux 
kernel for at91sam9x5ek. Please send e-mail to Linux kernel ML.

so is that change required globally? Why don't apply it to mainline then?

damn, it is http://patchwork.ozlabs.org/patch/198524/, correct? I should
have read the atmel related stuff more frequently these days. Sorry for
that, I was busy with nand related stuff on omap.

For at91sam9x5ek board, the environment offset in mainline is OK.
This patch is for other Atmel boards which I found there are overlap 
between u-boot and u-boot env.
