With this CLI tool you can configure the FPGA fabric with your rbf-file by accessing the FPGA manager from the HPS Linux of your Cyclone V SoC. Do not try to use it on devices other than Cyclone V SoC.

To better understand what this tool does, refer to Cyclone V Hard Processor System Technical Reference Manual and Cyclone V HPS Register Address Map and Definitions.

Note: I have successfully tested the tool on the Terasic DE10-Nano and the Enclustra PE1/SA2, each on Buildroot. Presumably it should run on any Cyclone V SoC device on any Linux distro. When running old distro releases cross compile compatibilty issues with glibc library may happen, in which case you may want to consider upgrading to a new kernel and root file system, compile natively, or try using an older docker image.

If you don't want to use the release binary, you can build the tool from source.

• Build with Docker:

./build.sh

• Build with Cargo:

cargo build --release

Copy the tool from your host PC to the device, e.g. via SSH (use util/scp_tool.sh as example). On the device make sure to have access to the rbf-file, e.g. by mounting your SD card. Then run the tool (use util/config_fpga.sh as example).

Make sure RBF_PATH and CDRATIO are set correctly, e.g. 0x3 for the Terasic DE10-Nano and 0x2 for the Enclustra PE1/SA2. Refer to the documentation of your board if you are unsure.

Embedded Linux tool to configure your Cyclone V FPGA fabric from the HPS

Usage: fpga_config_tool [OPTIONS]

Options:
