I use linux 3.10 on IMX6Q,but there is problem,the GPU do not initialize success, and the linux can not go to the runlevel 5,and have the problem" /etc/init.d/rc_mxc.s line 1 command line not found".and the kernel auto into the runlevel 3. The command line the uboot give to the kernel is right.Is GPU initialize failed can caused this problem?
