As I know, the i2c port in arduino is i2c-6 device in edison yocto linux. But I cannot use the device directly( by i2ctool or open/ioctl way) ,because we have to set some related gpio to "muxselect" the i2c
In arduino, it will muxselect before using the i2c. Is there another way to do the similar thing without using arduino or mraa. I wish it is a shell command to enable i2c-6.
