Hello Susangrace Rapaka,
There is a recipe in place for 4.9 on the latest Community BSP for the Morty branch of the Yocto Project. However, it’s not a complete recipe and as I imagined I couldn’t bake it.
I added the following on the conf/local.conf file and tried baking linux-fslc-imx
PREFERRED_VERSION_linux-fslc-imx = "4.9"
But I got the following warnings:
NOTE: preferred version 4.9 of linux-fslc-imx not available (for item linux-fslc-imx)
NOTE: versions of linux-fslc-imx available: 4.1-2.0.x+gitAUTOINC+ee67fc7e07

Currently the supported kernel for both the BSP release and Community BSP is 4.X (verion varies depending on the BSP). I would recommend using these kernels unless you absolutely need a feature from kernel 4.9 that’s not available on previous versions, in which case you would need to adapt the mainline kernel to work for your MACHINE.
I hope this information helps!
Regards,
