=== Device mapping ===
==== UART ====
* UART2 and it is mapped to <code>/dev/ttymxc1</code> device in Linux
* UART5 and it is mapped to <code>/dev/ttymxc4</code> device in Linux
==== GPIO ====
GPIOs are mapped into banks each of which contains 32 pins. They are named as GPIO<bank>_IO<pin>
=== Device usage ===
==== UART ====
UART peripherals use standard Linux protocols.
==== GPIO ====
Under Linux the GPIOs can be manipulated su <code>sysfs </code> export or with the gpio tools.
