Warning: Boot regression in latest kernels (4.19, 5.10 etc.)
Thanks for the thread, @kuleszdl !
My pine64lts is now booting as expected with some help from @xalius - first time I saw dtc in action Smile
Strit has pushed an update in the Manjaro kernel with a patch so that the board will work - currently that is in the unstable branch: https://gitlab.manjaro.org/manjaro-arm/p...288e4b9dd2

In case someone has a system that can't boot at the moment but would like to, here is a summary of the great instructions from @xalius on how to adjust the dtb:
# Convert a dtb to text/source with
dtc -I dtb -O dts -o output.dts <input.dtb>

# Locate and change the following line which sets the state of the pin in the output.dts file from:
cd-gpios = <0x23 0x05 0x06 0x01>;
# to:
cd gpios = <0x23 0x05 0x06 0x00>;

# Compile back to dtb:
dtc -I dts -O dtb -o <newdtb>.dtb <input.dts>

You can see in the patch used for the kernel in Manjaro, that this changes the state from LOW (SoPine) to HIGH (Pine64-LTS).
Xalius posted a couple of images of the schematics on the #pine64 channel which outline the same.
# SoPine - Low
cd-gpios = <&pio 5 6 GPIO_ACTIVE_LOW>; /* PF6 /
# Pine64-LTS - High
cd-gpios = <&pio 5 6 GPIO_ACTIVE_HIGH>; / PF6 */

Device: Pinebook Pro 128GB No:246 / MainOS: Manjaro ARM
Godot and Flutter - creating something can be fun with the right tools!
