We have taken aIMX6DL reference board design. Now we would like customize it by adding some external peripherals like IMU (SPI), Pressure Sensor/Altimeter (I2C), GPS (UART/I2C) etc.
The reference board has provided external ports for I2C, SPI. is it sufficient that we connect peripherals (IMU, ALtimeter and GPS) toI2C,SPI, UART connections. or we need to make changes in software also.
If we need to make changes in software. then they should be made in host system and again they have to cross compiled or we can do it imx6 board once the board is booting.
What are all the files they need to be changed or modified. is there any document which briefly explains about addition of some external modules to reference designs.
