What are the steps to add support for a board not currently supported in the meta-adi layer? We have a project using the ad9625 on the zcu106 board. We are using petalinux 2021.1.

Hi pat,

Please check this documentation for that. Come back with potential questions you have after reading it.

Thanks for the response.  However, I have had no luck getting my device-tree to build.

I've followed the instruction,

My device tree is auto-generated when I do the build and it is called system-top.dts from the imported xsa file I get from the FPGA member of my team.

I've created a file pl-delete-nodes-system-top.dtsi, under project-spec/meta-user/recipes-bsp/device-tree/files

Added it to the bbfile

SRC_URI_append = "file://config \
file://system-user.dtsi \
file://pl-delete-nodes-system-top.dtsi"

When I do petalinux-build -c device-tree I get lots of errors:

Hi Pat,

sorry for the late reply...

No, that is not the dts you should be looking at. You should look at pl.dtsi and remove those nodes.
