    Hello all,
    I recompiled (following this tutorial) the Ubuntu Kernel for the UDOO-NEO to use UART6 port (/dev/ttymxc5) from the A9 and after installing the kernel I have lost a lot of features included in the default image that I downloaded from the downloads section:
    • OTG. I cannot connect a mousse or keyboard because it isn't recognized.
    • Ethernet connection across the USB.
    I have checked the kernel configuration before execute the command ARCH=arm make udoo_neo_defconfig and for example the OTG is disabled and I have doubts of if there are more important options disabled to work like the image downloaded from the webpage.

    My questions are:
    1. Is the udoo_neo_defconfig the configuration used to generate the image uploaded to the 'Downloads section'?
    2. Where can we find the same configuration used?
    Thanks in advance! Regards

    I have checked that I'm using the correct branch. To download the source code I have executed the command:


    To check the branch dowloaded I have executed the next commands:
    user@satcom-vm:~/udoo-dev/linux_kernel$ git rev-parse --abbrev-ref HEAD
    3.14-1.0.x-udoo

    BR

    I have changed the order of the actions and now is working perfectly:
    1. Compile the kernel modified and load it in the SD card following the instructions.
    2. Use the 'Device Tree Editor' to add the second serial port.

    But you still patched the kernel to be able to have uart6 (second serial) running properly?

    I have applied the patch and updated the Device Tree Editor and I can use the UART6 with all the functionalities of the default image.
