I am looking for any word on the I2C2 issues, specifically the fact that we can not drive an SF/11 C rangefinder on the external I2C bus (aka I2C2) of the PIxhawk 2. I know you can use if if you use the serial port but that is taken. Also, there is an issue with using a 2nd GPS unit with the Pixhawk 2 that is also firmware related. Any love on these issues by chance? (I did not see anything posted on the changes for 3.5).
