I wonder why gps is only running in the second I2C if it should be default the first I2C connection, as shown in the Erle Brain 3 wiring, how do we change the port to the defaults. Because we don't have another i2c hardware to test, only GPS, our telemetry 915 MHz is USB, we'll test after GPS runs in the proper i2c port, according Erle Brain default wiring, to make things easy to the students. I have found in forum related subject but nothings we could use to change the GPS i2c port to the defaults,
PS.: We backup the Erle default factory Frambuesa OS config and use it without changing substantially to avoid lose of general rover parameters.
PS2. I have followed the instructions from the previous post about GPS configuration.
