Hello,

I would like to know if your FPGA was configured before doing the overlay. Furthermore, does the system hangs after doing this overlay? Which Device is this?

Thanks

    Fpga is configured from u-boot. rbf is loaded with load command in u-boot on boot time. problem is when loading from linux. The board used is de10-nano which has altera cyclone V SOC. System doesn't hang after doing the overlay. What is the meaning of the error. Is it like the nodes that we are provide in the overlay file is not present in the base dtb file. It also says no such device. Also do we have to avoid configuring the fpga from u-boot for overlay to work? I tried removing the rbf file which is loaded from u-boot. In this case linux doesn't boot.
