Building the toolchain (For developers)

The current process for building the toolchain is manual, and only for Linux

Follow theses steps:

1. Install Nix

2. Clone this repo

3. From the repo's home folder execute nix develop

   • The first time it will take around 20 minutos to finish
   • All the tools will be built
   • After that, you will see the prompt: [nix(openXC7)]
   • Next execution of nix develop will take seconds

4. From the nix environment execute ./openxc7-pack.py

   It will collect all the necesary binaries an libraries and generate a tarball. This is what you should see initially:

After some time, it will generate the apio-openxc7-linux-x64-<version>.tgz package

5. You are done! You can use it locally or publish it as a new release

Using the toolchain without APIO

It is possible to use the complete toolchain directly, without apio. Follow this instructions: ./install.sh

1. Install the complete toolchain (oss-cad-suite + openxc7)

./install.sh

It will download the corresponding .tgz packages and uncompressing them in the user's folders: ~/.config/openxc7 and ~/.local/openxc7

2. Enter the new environment: . start

. start

Inside this environment you have accesss to all the tools: yosys, nextpnr-xilinx, openFPGAloader and son on

3. Test the "hello world": Turning the LED on

cd example
make

It will generate the Bitstream

4. Upload to the Basys3 board

Execute the command make prog

The LED 15 of the Basys3 board is now on
