Environment Setup

Getting the right environment setup for this was a huge pain. Needed Ubuntu 20.04 image, then install:

   sudo apt-get install autoconf automake autotools-dev curl python3 libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev git

You will need to clone the following repos:

   git clone https://github.com/riscv-collab/riscv-gnu-toolchain.git
   git clone https://github.com/defconfurs/dcfurs-badge-dc28.git

Enter the RISCV folder and perform:

   ./configure --enable-multilib
   make

Enter the dcfurs badge folder and verify the following gives no errors:

   ./make.py build
