[IMX8MMINILPD4-EVK][Yocto] Append kernel command-line

I am implementing factory-reset by using meta-readonly-rootfs-overlay. It required to update kernel command-line, and I tried as Yocto document:

"The Linux kernel command line is typically specified in the machine config using the APPEND variable. For example, you can add some helpful debug information doing the following:

     APPEND += "printk.time=y initcall_debug debug" "

Although added the APPEND in imx8mmevk.conf and local.conf also, kernel command-line was not updated.

Is this correct way to update kernel command-line?


Thank you,
