    Is it possible to enable uart ttymxc2 and ttymxc4 in udoobuntu2? I have used the same procedure needed in udoobuntu, but the two sockets don't appear. What i need to do?
    Thanks!

    Dear dxmann,
    UDOObuntu 2 is based on Kernel 3.14 device tree. The muxing is managed by device tree. You need to enable this UART device in the dts file of UDOO Dual/Quad: imx6qdl-udoo.dtsi

    Is there a tutorial where the procedure is explained? I'm not expert in kernel management :)

    We'll release such a tutorial for sure. I'm working this very moment on the documentation to achieve a very good level of clarity. We've passed to device tree not so much time ago (since we passed to Kernel 3.14 actually)

    It seems some of the periphials are missing from the device tree manager. How do you enable unlisted perphials (for example, pwm pins other than pins 2 and 5, which are visable in the device tree manager)

    Andrea, yea I've seen that, and it isn't quite what I am looking for. I was referring to the pwm hardware on the A9 side of the chip
