I have an Atmel atngw100 development board and a standalone application that crashes within 10 to 30 seconds of starting. I have just discovered that 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. Assuming I don't have a hardware fault, does the above show that the configuration provided by Atmel does not work properly (or am I missing something)? Note: U-boot will also crash if I did the loop test on an address in the ap7000's internal SRAM, but I assume the actual code for running the loop test is in SDRAM. So, if SDRAM is not being initialized correctly, this may be the reason the loop test crashes. Any comments, help or advice will be greatly appreciated.
