Repository about a SoC with wireless capabilities build with LiTex for FPGA.

git clone https://[email protected]/authscm/ptanguy/git/stage-terrine/stage-terrine.git
git submodule init
git submodule update

Setup env:

make pyenv
source venv/pyenv/bin/activate
pip3 install -r requirements.txt

Fix picolibc missing data:

cd third_party/pythondata-software-picolibc
git submodule init
git submodule update

Install toolchain:

cd third_party/litex
./litex_setup.py --gcc=riscv

Install openocd:

sudo apt-get install openocd

Setup vars env:

export LITEX_ENV_VIVADO="INSTALL-PATH/Xilinx/Vivado/2020.2"                       
export PATH="INSTALL-PATH/riscv64-unknown-elf-gcc-8.3.0-2019.08.0-x86_64-linux-ubuntu14/bin:$PATH"

Generate bitstream:

make gateware CPU_TYPE=(cv32e41p/vexriscv) VARIANT=(standard/HIDS_SYNTH) 

Load bitstream:

make load_bitstream CPU_TYPE=(cv32e41p/vexriscv) VARIANT=(standard/HIDS_SYNTH)

Compile application:

make compile_app APPLICATION=(demo/demo-lora/demo-loramacnode)

Load application via serial

make load_app APPLICATION=(demo/demo-lora/demo-loramacnode)

To start the loading process press button BTNC on basys3

In the following we suppose that you have the Pip software for Python3. If not on a debian you can install it such as:

sudo apt install python3-pip

Install dependancies:

pip install -r doc/requirements.txt

It will install Sphinx which is a tool that makes it easy to create documentation.

To generate and read the doc:

make -C doc html
firefox doc/build/html/index.html

• [] add interrupt support to manage RFM95w interrupt
• [] add support to manage Dragino LoRa shield v1.4 with Arty A7 board
• [] add submodule for LoRa-MAC node stack and fork it to add support for LoRa Shield by following the steps details here Lora-net/LoRaMac-node#1101 or by following the porting guide https://stackforce.github.io/LoRaMac-doc/LoRaMac-doc-v4.5.1/_p_o_r_t_i_n_g__g_u_i_d_e.html
