SparkRoad-FPGA

The SparkRoad is a FPGA board with low cost per logic element and convenient USB bitstream programming capability. It is compatible with the micro:bit and is a perfect fit for breadboards. The heart of the SparkRoad board is a EG4S20NG88 FPGA from Anlogic.

Quickstart

git clone https://github.com/verimake-team/SparkRoad-FPGA.git
cd SparkRoad-FPGA

If you have compiled a complete toolchain for riscv Please skip the following commands.

build the toolchain on ubuntu 16.4:

For well-known reasons, we provide a mirror of toolchain for a pure rv32i here。

Make sure the mirror above is in the directory /SparkRoad-FPGA.Then the following commands will build the RISC-V GNU toolchain and libraries for a pure RV32I target, and install it in /opt/riscv32i:

sudo mkdir /opt/riscv32i
sudo chown $USER /opt/riscv32i
make get-tools
sudo tar -zxvf riscv-gnu-toolchain-rv32i.tar.gz
sudo chown $USER riscv-gnu-toolchain-rv32i
cd riscv-gnu-toolchain-rv32i; mkdir build; cd build
../configure --with-arch=rv32i --prefix=/opt/riscv32i
make -j$(nproc)
cd ../../RISC-V/firmware
gcc -Wall rom2mif.c -o rom2mif
sudo mv rom2mif /opt/riscv32i/bin

export PATH

You can input the following at the end of profile use vi /etc/profile .

export PATH="$PATH:/opt/riscv32i/bin"

Then log out and reload your ubuntu.

build the toolchain on windows10:

Just install risc-v-toolchain.exe which provide by Anlogic. Then export PATH.
