Just read a little on the MPU watchdog timer. It looks like the default values would have caused a reset after ~10s. So if your board is rebooting after 4 minutes, maybe the bootloader is turning it on? I've left a board on in the bootloader for hours without seeing a reboot, so either the bootloader I was using disables the watchdog, or it's not armed at reset. - Anand-- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
