Introduction

FuseSoC is a package manager written in python and used to assemble different HDL design from libraries together. FuseSoC is like Buildroot or Yocto used for Linux, it's just a «Makefile» that launch different tools to build the system.

Install fusesoc

• Fusesoc is a python3 package that can be installed with pip :

$ python3 -m pip install fusesoc

• To be up to date use --upgrade option:

$ python3 -m pip install --upgrade fusesoc

• Once installed a command named fusesoc is available on system :

$ fusesoc --version
1.11.0

• Initialize library:

$ cd workspace
$ fusesoc init

Blinky

Blinky is a project that aim do blink all FPGA board with a gateware constructed from fusesoc tool.

Here the way to blink Armadeus board with blinky.

First, git clone the blinky project:

$ cd workspace
$ fusesoc library add --sync-type git blinky https://github.com/fusesoc/blinky

APF27

• If you have ISE installed correctly, you can synthesize blinky with following command:

$ fusesoc run --target=apf27 fusesoc:utils:blinky

• As we don't configure fpga with impact, the build will finish with an error :

ERROR: Failed to run fusesoc:utils:blinky:1.0 : 'impact' exited with an error code

• But the bitstream will be generated in :

./build/fusesoc_utils_blinky_1.0/apf27-ise/blinky.bit

• To configure the FPGA, copy it under your /tftpboot/ directory then download it with U-Boot:

cp ./build/fusesoc_utils_blinky_1.0/apf27-ise/blinky.bit /tftpboot/

• Under U-Boot

BIOS> tftpboot blinky.bit
BIOS> fpga load 0 ${loadaddr} ${filesize}

• Admire the flashing LED

OPOS6UL_SP

• If you have ISE installed correctly, you can synthesize blinky with following command:

$ fusesoc run --target=op6sp fusesoc:utils:blinky

• As we don't configure fpga with impact, the build will finish with an error :

ERROR: Failed to run fusesoc:utils:blinky:1.0 : 'impact' exited with an error code

• But the bitstream will be generated in :

./build/fusesoc_utils_blinky_1.0/op6sp-ise/blinky.bit

• To configure the FPGA, copy it under your /tftpboot/ directory then download it with U-Boot:

cp ./build/fusesoc_utils_blinky_1.0/op6sp-ise/blinky.bit /tftpboot/

• Under U-Boot

BIOS> tftpboot blinky.bit
BIOS> fpga load 0 ${loadaddr} ${filesize}

• Admire the flashing LED : Fix the configuration bug.
