Linux workstation
Hi3861 WLAN module
USB Type-C cable used to connect the Linux workstation to Hi3861 development board
The following table lists the tools required by the Hi3861 WLAN module.
**Table 1 Tools required by the Hi3861 WLAN module
Development Tool | Description |
---|---|
SCons3.0.4+ | Executes script compilation. |
Python modules: setuptools, Kconfiglib, PyCryptodome, six, and ecdsa | Executes script compilation. |
gcc riscv32 | Executes script compilation. |
Perform the following steps to install the necessary tools:
Run the following command to install the SCons installation package:
python3 -m pip install scons
Run the following command to check whether SCons is successfully installed. If the installation is successful, the query result as shown in Figure 1 is displayed.
scons -v
Figure 1 Successful SCons installation (the version must be 3.0.4 or later)
Install setuptools.
pip3 install setuptools
Install the GUI menuconfig tool (Kconfiglib). You are advised to install Kconfiglib 13.2.0 or later.
Command line:
sudo pip3 install kconfiglib
Installation package:
Download the .whl file, for example, kconfiglib-13.2.0-py2.py3-none-any.whl.
Download path: https://pypi.org/project/kconfiglib#files
Install the .whl file.
sudo pip3 install kconfiglib-13.2.0-py2.py3-none-any.whl
Install PyCryptodome using either of the following methods:
Install the Python component packages on which the file signature depends, including PyCryptodome, six, and ecdsa. As the installation of ecdsa depends on that of six, install six first.
Command line:
sudo pip3 install pycryptodome
Installation package:
Download the .whl file , for example, pycryptodome-3.9.9-cp38-cp38-manylinux1_x86_64.whl.
Download path: https://pypi.org/project/pycryptodome/#files
Install the .whl file.
sudo pip3 install pycryptodome-3.9.9-cp38-cp38-manylinux1_x86_64.whl
Install six using either of the following methods:
Command line:
sudo pip3 install six --upgrade --ignore-installed six
Installation package:
Download the .whl file, for example, six-1.12.0-py2.py3-none-any.whl.
Download path: https://pypi.org/project/six/#files
Install the .whl file.
sudo pip3 install six-1.12.0-py2.py3-none-any.whl
Install ecdsa using either of the following methods:
Command line:
sudo pip3 install ecdsa
Installation package:
Download the .whl file, for example, ecdsa-0.14.1-py2.py3-none-any.whl.
Download path: https://pypi.org/project/ecdsa/#files
Install the .whl file.
sudo pip3 install ecdsa-0.14.1-py2.py3-none-any.whl
NOTICE
The Hi3861 platform supports only the static link of the libgcc library. The dynamic link is not recommended because version 3 of the GNU General Public License (GPLv3) will be polluted during commercial distribution.
Steps 2 to 14 of the following procedure are used to build the gcc_riscv32 image. You can simply download the image and skip these steps.
Start a Linux server.
Download the RISC-V GNU toolchain.
git clone --recursive https://gitee.com/mirrors/riscv-gnu-toolchain.git
Open the riscv-gnu-toolchain folder and delete empty folders to prevent conflicts during the download of Newlib, Binutils, and GCC.
cd riscv-gnu-toolchain && rm -rf riscv-newlib && rm -rf riscv-binutils && rm -rf riscv-gcc
Download RISC-V Newlib 3.0.0.
git clone -b riscv-newlib-3.0.0 https://github.com/riscv/riscv-newlib.git
Download RISC-V Binutils 2.31.1.
git clone -b riscv-binutils-2.31.1 https://github.com/riscv/riscv-binutils-gdb.git
Download RISC-V GCC 7.3.0.
git clone -b riscv-gcc-7.3.0 https://github.com/riscv/riscv-gcc
Add the RISC-V GCC 7.3.0 patch.
Visit the GCC official patch links 89411 and 86724, and manually add the changes to the .c and .h files based on the requirements in the patch links. Note that the number of rows may not match because of different versions of the patch and GCC. You need to search for the keyword in the patch to locate the corresponding row.
Download, decompress, and install GMP 6.1.2.

Set the environment variable.
NOTE If you are using the riscv32 gcc package, run the following command to decompress the package to the root directory:
tar -xvf gcc_riscv32-linux-7.3.0.tar.gz -C ~
vim ~/.bashrc
Copy the following command to the last line of the .bashrc file, save the file, and exit.
export PATH=~/gcc_riscv32/bin:$PATH
Validate the environment variable.
source ~/.bashrc
Check whether the compiler is successfully installed. If the compiler version number is correctly displayed, the installation is successful.
