Buildroot on Beaglebone?

[RobertCNelson]

@sam-bristow

As far as I can tell the device-tree overlay stuff is handled by u-boot and then handed off to the Kernel as a Flattened Device Tree. Are the CapeMgr patches still required for both the kernel and u-boot?

Is there any up-to-date documentation about how the various parts are supposed to work together?

I’m using the 2020.05.x LTS branch of Buildroot with the 5.6 kernel and 2020.04 u-boot.

We only support u-boot overlays, with a single patch to the linux kernel “-@” for exporting the device tree label’s…

then you just need the 2 u-boot patches:
