6. Porting to non-Raspberry Linux¶

The SDK uses a shared library to connect to the chip over the i2c device. The SDk is comes with a shared library compiled for Raspberry Pi3 (armv7l) which uses in the end /dev/i2c-1 device to access the Security Chip.
If the default library doesn’t work for your setup or architecture, you might need to build the shared library for your platform.
For this you need to have cmake and build-essential packages installed in your system. Additionally, if you have OPTIGA connected to other than /dev/i2c-1 device, you might need to change this value here before you continue with other steps
Then you can do the following:
pi@pi:/home/pi/git$ git clone https://github.com/Infineon/python-optiga-trust
pi@pi:/home/pi/git$ cd python-optiga-trust/optigatrust/csrc
pi@pi:/home/pi/git/python-optiga-trust/optigatrust/csrc$ mkdir build && cd build
pi@pi:/home/pi/git/python-optiga-trust/optigatrust/csrc/build$ cmake ..
pi@pi:/home/pi/git/python-optiga-trust/optigatrust/csrc/build$ make
