Dear Yocto experts,

As all our yocto bsps for other hardware platforms support are
developed on yocto sumo version, (And I was able to do the build setup
for imx-linux-rocko ie., yocto rocko version), but now I need to do
for sumo version as this is followed and maintained unique for all our
hardware platfroms, In fact I see for imx-linux-sumo support also
exists, when I try to do this yocto sumo version of build setup using
the below command, I am seeing the below issue, Could you please do
the needful in resolving the below issue
