Hi Manju, I guess I'm definitely not understanding. I'm using a custom machine defined here ( https://github.com/kratsg/meta-l1calo/blob/master/conf/machine/gfex-prototype3.conf) which does inherit from zcu102-zynqmp -- but I override the MACHINE_DEVICETREE setting here. From what I understood, u-boot should be picking this up. (My custom layer is in bold below)
