Hi Peter,

Thank you for catching this. I will take care of getting this corrected with a follow up patch.
The way zynqmp_virt_defconfig works is described on our wiki page below:
https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841973/Build+U-Boot
The reason why this was working for me is because I had the DEVICE_TREE environment variable set when building.
make distclean
make xilinx_zynqmp_virt_defconfig
export DEVICE_TREE="zynqmp-zcu106-revA"
make
What is the proper way for setting an environment variable with buildroot? Should I add this as a pre-build script in each defconfig?
Best regards,
Neal Frager
