How to read BNO055 sensor data in a Simulink Model on a BeagleBone Black

I am trying to build a real-time application on BeagleBone Black using Simulink. I need to get orientation data from a BNO055 Intelligent 9-axis absolute orientation sensor. I know this can be done by using the Adafruit library in python on the Beaglebone, but I am not able to figure out how to do it using Simulink.

i too have the same problem

If you have a C/C++ library for beaglebone that will let you read/send data over I2C (that's what BNO055 uses), then you can either use legacy code tool to generate MEX-C file for simulation and code generation or alternatively an MATLAB Function block with coder.ceval() inside to call C/C++ functions from I2C library.

On Linux based MCU's, reading a hardware interface like I2C usually boils down to reading a specific file from the device memory, so you gonna use the linux basic file IO library and some code to parse data.
