Hello there, I am using minimal ubuntu on the NEO platform. In the documentation I have found the device tree editor: http://www.udoo.org/docs-neo/Cookbook_Linux/Device_Tree_Editor.html Also in the /boot/dts/ directory I can find some compilled dts files. For full they are: Code: -rwxr-xr-x 1 root root 47563 Jan 24 10:28 imx6sx-udoo-neo-full.dtb -rwxr-xr-x 1 root root 48824 Jan 24 10:28 imx6sx-udoo-neo-full-hdmi.dtb -rwxr-xr-x 1 root root 49476 Jan 24 10:28 imx6sx-udoo-neo-full-hdmi-m4.dtb -rwxr-xr-x 1 root root 48658 Jan 24 10:28 imx6sx-udoo-neo-full-lvds15.dtb -rwxr-xr-x 1 root root 49310 Jan 24 10:28 imx6sx-udoo-neo-full-lvds15-m4.dtb -rwxr-xr-x 1 root root 48850 Jan 24 10:28 imx6sx-udoo-neo-full-lvds7.dtb -rwxr-xr-x 1 root root 49502 Jan 24 10:28 imx6sx-udoo-neo-full-lvds7-m4.dtb -rwxr-xr-x 1 root root 48215 Jan 24 10:28 imx6sx-udoo-neo-full-m4.dtb But in the example screen from the device tree editor I can see one can set various peripherals using the available device trees. But I cannot see .dtb files for uart, CAN, SPI and etc in the /boot/dts/ directory. I uderstand that the minimal image doesnt have the device tree editor, so I need to set them using command line. But where are the rest of the .dtb files located? Also are the .dts sources also available? I would appreciate all help!
