Linux how to build airspy firmware

Prerequisites to build firmware (Tested on Ubuntu 20.04 LTS):

Warning other version of GCC ARM like GCC ARM 4.9 2014q4 does not work correctly and build fail or have issues, so ONLY use GNU_ARM_4_7_2013q3 to build the firmware.

• Open a shell and type following commands:

cd ~
sudo apt-get install gcc-multilib git dfu-util python
wget https://launchpad.net/gcc-arm-embedded/4.7/4.7-2013-q3-update/+download/gcc-arm-none-eabi-4_7-2013q3-20130916-linux.tar.bz2
tar xjf gcc-arm-none-eabi-4_7-2013q3-20130916-linux.tar.bz2
echo 'PATH=$PATH:~/gcc-arm-none-eabi-4_7-2013q3/bin' >> ~/.bashrc
git clone https://github.com/airspy/firmware.git airspy_fw
cd airspy_fw
cd ./scripts
sudo python get-pip.py
sudo python -m pip install GitPython --upgrade

Note1:

• If you are using a new Python 3.x by default you can get/use get-pip.py for Python3 using wget https://bootstrap.pypa.io/get-pip.py

Note2:

• For get-pip.py if you need a proxy for internet access set following variables before to launch python get-pip.py:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py

Build airspy firmware:

• Open a shell and type following commands:

cd ~
cd ./airspy_fw/libopencm3
make clean
make
sudo make install

Build airspy_fw:

cd ~
cd ./airspy_fw/
make clean
make

In case of error during build like:

Traceback (most recent call last):
  File "../scripts/airspy_fw-version.py", line 14, in <module>
    git=Repo(search_parent_directories=True).git
TypeError: __init__() got an unexpected keyword argument 'search_parent_directories'
make[1]: *** [airspy_m0.hdr] Error 1

Just execute

sudo python -m pip install GitPython --upgrade

Then relaunch the build
