I am using uboot-2013.01, with at91sam9g20ek_2mmc and I am trying to
build for dataflash, using at91bootstrap-1.16, and buildroot-2011.11
Initially I built for nand flash, with a patch to boards.cfg and
at91sam9260ek.c
This was fine if I used the reset button, but from a cold boot, startup
stopped after after at91bootstrap-1.16, and uboot never starts.
Now I am trying to build uboot for all dataflash, but I still see the
same behavior with uboot.
Uboot worked from dataflash when using uboot-1.3.6 (and patches from
atmel), but much has changed since then, so it is hard to figure out if
something from those patches is lost in the current uboot.
What can I try next.
Bellow are the patches I applied so far.
boards.cfg: add target name
