Applying U-boot overlay from the command line?

In the past, I'd apply an overlay by catting some stuff to .../slots. That no longer shows up in my sysfs.

I'm working on a U-boot overlay, but while experimenting, is there a way to apply the overlay from the command line after boot?

Nope all done in /boot/uEnv.txt on boot

Okay thanks.

Actually, there is a way, Jason K figured this out late last week and
it has not been fully documented out side of the training yet...

We haven't figured out how far back this goes with mainline kernels
but, create a directory under:



sudo mkdir -p /sys/kernel/config/device-tree/overlays/accel/

then just echo the *.dtbo into the ./dtbo file created in the directory above..
