I use imx6 dual lite board with Green hills integrity OS 11.0.4 and have problem in reset :

1-When u-boot loads kernel and write reboot command , the system reset and u-boot detect reset issue is watchdog
but the kernel loaded but the system halted after 16 seconds.
2-When u-boot loads kernel and push reset button , the system reset and u-boot detect reset issue is POWER
but the kernel loaded but the system halted after 16 seconds.
3-When you stop u-boot and write reset command of u-boot ,the u-boot reset and u-boot detect reset issue is watchdog
and the system continue correctly and loads kernel and works fine
