Hallo, I have also a AT91SAM9260 board.
I have found out a strange behaviour. case 1: When the flash is empty it works fine. No problem. case 2: When the board is configured to boot u-boot from parallel Flash. I get also errors and the reset script does not work. In the reset script is the configuration for the externel Flash and RAM. I need this for downloading. The interesting is I can set the same commandos like in the reset script over telnet step by step.
