I guess you already got this working on T30 in the past, so you only need to change to the iMX6 implementation which uses the new Toradex libraries (that’s where you will find the i2c.h, gpio.h and the required libraries to be able to build and link your project)
Yes, our actual design works with T30 and we only want to change to iMX6.
Thanks for the information. I am out of the office during the next weeks, I will be able to test probably by the end of August; I will keep you informed then.
