Boot from dataflash problem - Paulo Silva - Feb 28 14:30:40 2008
Hi all,
I boutgh an Olimex SAM9-L9260 board that cames with linux running from nand flash, but I neew to run my application from dataflash.
I followed the instructions on http://www.linux4sam.org/twiki/bin/view/Linux4SAM/AT91Bootstrap to put a bootstrap into dataflash, after this I thing that when I reset the board with a terminal connected into dbgu board connector, I should not see romBoot prompt, because it would find the bootstrap into the dataflash, and put it into internal sram and execute it.
This thought is correct? What am I doing wrong?
Best regards
