 ### Synthesis and bitstream creation for FPGAs
-You need to set FPGA\_BOARD in [./common.mk](./common.mk) to the name of a directory inside [./system/fpga\_config/](system/fpga_config/). You should also check inside your board directory for config.mk for further board-specific configuration options. Then you can run `make upload` in the top level directory and it should create the bitstream and upload it.
