[Qemu-discuss] Unable to boot imx6q base sabrelite linux kernel on QEMU.

[Bilal, Muhammad]

Hi,


What is the right command to emulate linux kernel for sabrelite machine ?


I'm trying to emulate imx6q linux kernel with following command line.


qemu-system-arm -m 1G -M sabrelite -kernel zImage -drive 
file=console-image-mx6q-rootfs.ext3,format=raw,id=mycard -device 
sd-card,drive=mycard -append "console=ttymxc0 rootfstype=ext4 
root=/dev/mmcblk0p0 rw rootwait init=/sbin/init" -nographic -dtb 
zImage-imx6q-sabrelite.dtb -smp 4
