Hi,

I think it would be interesting information to know "how" you change the value inside "u-boot-at91/sama5d3_xplained_nandflash_config".

As every time you rebuild it may be redownloaded, you should do this via a patch to append to the recipe.

Are you doing this? Or just changing it locally?

If you give some more info probably we can better help!

Cheers,

Federico

perhaps asking it on https://github.com/linux4sam/u-boot-at91 via
github issues might be helpful too.
