I customize kernel on BBB, enabled
mount -t configfs none /sys/kernel/config
No error but I don’t see the folder /sys/kernel/config/device-tree/overlays exist.
only /sys/kernel/config is available.
Anyone know what I am missing, please?
That was last supported in the v4.14.x-ti kernel…
I am using buildroot with am335x-boneblack config, but point to 5.10 kernel.
if I back to 4.14 this feature should work? If so, is there any similar way to do that on 5.10?
The patchset that enables that needs rework after v4.15.x
I thought CONFIG_OF_OVERLAY and CONFIG_CONFIGFS are linux standard config flags, once enabled then good to go
Could you please give the link of the patchset?
they are… but the patchset to make them work together is not mainline…
Seems a lot of rework between 4.14 and 5.10
Is there any other simple way to load dynamic device tree overlay, please?
it was going to be a lot of rework from 4.14.x → 4.15.x/4.16.x hence why it wasn’t done by me…
Thank Robert, from your hint, I got it working by weekend. Not easy!
I would like to install the config-pin which is really nice. I remember there is an overlay that need for this tool but could not find anywhere now. Can you show us if you know where it is?
