Hi nxp community:


I am working on industial imx6q. DDR3 ic: IS43TR16256AL(industrial standard).


using downward command to kill watchdog daemon to make imx6q reboot


mount -o remount,rw / && mv /sbin/watchdogd /             #  android 4.4 debug console operation
kill -9 `ps | grep watchdogd | busybox awk '{print $2}'`    # kill /sbin/watchdogd to let /dev/watchdog go


echo 1 > /dev/watchdog                                                   # qt 4.8.5 system, wait for a short time, imx6q reboot


then, imx6q reboot, but always stack at kernel. Can not run into system, no matter android or qt
