karimbakir — Mon, 20 Nov 2017 16:59:25 GMT

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

Hi karim

for reliable reboot it is necessary to implement reset circuit as it is done

on Sabre SD schematic spf-27392 p.21 (U507), also resetting pmic with PWRON:
