The overlay looks the same as in Linux and documented in fpga-region.yaml. For example, if your device tree contains a node with a fpga-region for the fpga named fpga_full and the fpga-mgr property has a phandle to the node of the FPGA Manager, the following overlay should instruct the FPGA Manager to load the bitstream.bit firmware into the FPGA. /dts-v1/; /plugin/; &fpga_full { firmware-name = "bitstream.bin"; }; In the overlay you should also describe the gateware implemented in the bitstream. This allows Linux to detect what's actually implemented in the bitstream and probe the proper drivers. Michael
