I’m migrating a device from Yocto thud to scarthgap and moving from a custom 4.1 kernel (fmntf/linux_kernel 4.1.15_2.x-udoo) to linux-fslc-imx 6.6. Hardware is Udooneo Extended (iMX6SoloX) with the stock 7" LVDS panel (UMSH-8596MD-20T w/ DS90CF364 + ST1332 touch).

Goal: run X11 with etnaviv (hardware accelerate) because the newer imx-viv-gpu doesn’t support X11 for our Electron apps.

What works:

From what I understand, I only have UART6 available to use, but those pins by default are used for GPIO. To use UART6 I first need to edit the device tree, but it seems that the device tree editor is only available to use in UDOObuntu.

This means I need to use the device tree editor in UDOObuntu running on the UDOO Neo, then copy the resulting files into a VM running Ubuntu and build Android. Once I reconfigure the...
