==Peripheral UART ==
From the Carrier <code>imx6ul-axelulite-cb003a.dts</code> device tree:
<pre>
&uart3 {
...
...
[ 0.437613569198] 2020000.serial: ttymxc0 at MMIO 0x2020000 (irq = 2130, base_baud = 5000000) is a IMX[ 1.167221] console [ttymxc0] enabled[ 1.172839344706] 21ec000.serial: ttymxc2 at MMIO 0x21ec000 (irq = 5865, base_baud = 5000000) is a IMX
...
...
</pre>
For exmapleexample, using a loopback HW connection (RX shortcircuited short circuited to TX on UART232 port) it is possibile possible to test the send and receive data using the <code>ttymxc2</code> device:
<pre class="workstation-terminal">
root@desk-mx6ul-axelulite:~# stty -F /dev/ttymxc2 115200 -echo
root@desk-mx6ul-axelulite:~# cat /dev/ttymxc2 &
[1] 331267
root@desk-mx6ul-axelulite:~# echo "Test loopback" > /dev/ttymxc2
</pre>
