Are other applications (including U-Boot itself and maybe Linux) running fine?
the special memory test described in 5.9.2.10 of DULG also crashes the board after a similar amount of time.
With a fresh copy of the Atmel's release of the U-boot binary installed (version 1.1.3-00248-gae9bc0c), I press SPACE to abort autoboot, and then type:
loop .b 10400000
(10400000 is an address in SDRAM) Nothing happens for about 20 Seconds, then there is an 'Unhandled exception' and the processor reboots.
Is there by chance any watchdog on your system that mith have such a timeout / reset period?
Best regards,
Wolfgang Denk
