AVR 90USB1287 software reset

AVR 90USB1287 software reset

2007-07-16 by Tim Mitchell

I'm trying to do a software restart on an AVR90USB1287. (basically a
mega128 with USB).

I am disabling interrupts, turning on the watchdog timer and going into
an endless loop. When the watchdog times out, it resets, but does not
run my software (I am not sure what it is doing, or how to tell). The
hardware boot flag is disabled and bootrst is disabled so it should not
be jumping to the bootloader.

It starts up fine into the software on power up.

Anyone got any advice on what it might be doing?
