I'm trying to use I2C to control the camera. But it does not working. When I check it with linux i2c-tool, it shows no I2C bus. Has anyone tried and succeeded on the test like this blog. https://96boards.org/blog/programing-i2c-devices-libmraa-libupm/
I don't remember seeing any success stories about I2C on bubblegum. It is quite possible that you are the first person to try!
