PULP Toolchain and SDK
PULP Toolchain installation
Ubuntu version: 22.04.4
Open new terminal to create new directory:
cd
cd /opt
sudo mkdir riscv_pulp
cd riscv_pulp
sudo mkdir bin
Setup path:
nano ~/.profile
Add
if [ -d "/opt/riscv_pulp" ] ; then
PATH="/opt/riscv_pulp:$PATH"
fi
Invoke command below to take effect
source ~/.profile
Open new terminal to install toolchain:
Prerequisite
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev
Follow these steps to install toolchain:
git clone https://github.com/pulp-platform/pulp-riscv-gnu-toolchain
cd pulp-riscv-gnu-toolchain
Then update submodule
git submodule update --init --recursive
Because /opt/riscv/bin is in root, so must use sudo when make
./configure --prefix=/opt/riscv_pulp --with-arch=rv32imc --with-cmodel=medlow --enable-multilib
sudo make
PULP SDK installation
Open new terminal to install pulp-sdk
Prerequisite
sudo apt-get install -y build-essential git libftdi-dev libftdi1 doxygen python3-pip libsdl2-dev curl cmake libusb-1.0-0-dev scons gtkwave libsndfile1-dev rsync autoconf automake texinfo libtool pkg-config libsdl2-ttf-dev
Follow these steps:
pip install argcomplete pyelftools
pip install prettytable
Clone pulp SDK :
git clone https://github.com/pulp-platform/pulp-sdk.git
cd pulp-sdk
Then update submodule
git submodule update --init --recursive
Edit file pulp-sdk/configs/pulp-open.sh, put the command below under line 32
export PULP_RISCV_GCC_TOOLCHAIN=/opt/riscv_pulp
Build gvsoc
source configs/pulp-open.sh
make build
Note
Always run command source configs/pulp-open.sh to select board before running or doing anything in pulp-sdk directory
First simple test
Select board and then go to project
cd pulp-sdk
source configs/pulp-open.sh
cd tests/hello
Build project
make clean all run
The last line appear with Hello from FC without any error then you success.
Follow the command below to have gtkwave
make clean all run runner_args="--vcd"
This time view.gtkw with appear in project, as long as all.vcd in BUILD/PULP/GCC_RISCV folder.
Run the code below to see wave
gtkwave /home/ryan/pulp-sdk/tests/hello/BUILD/PULP/GCC_RISCV/all.vcd /home/ryan/pulp-sdk/tests/hello/view.gtkw
Tip
To run other project outside pulp-sdk, just move project folder to path pulp-sdk/tests/ and then run.
