Hello,
I am trying to convert my workflow to start using Torizon OS 7. For customizing the image, I use torizoncore-builder but the overlay that I use for a 7inch LVDS touch panel produces the following error:
=> Adding device-tree overlay 'overlays/verdin-imx8mp_dsi-to-lvds_panel-cap-touch-7inch-lvds_overlay.dts'
'verdin-imx8mp_dsi-to-lvds_panel-cap-touch-7inch-lvds_overlay.dts' compiles successfully.
Failed to apply '/tmp/tmpeh9ew945': FDT_ERR_NOTFOUND
error: cannot apply device tree overlays ['/tmp/tmpeh9ew945'] against device tree /storage/dt/usr/lib/modules/6.6.54-7.1.0-devel-gf7321c633d93/dtb/imx8mp-verdin-wifi-dahlia.dtb.
error: overlay 'overlays/verdin-imx8mp_dsi-to-lvds_panel-cap-touch-7inch-lvds_overlay.dts' is not applicable.
It worked without issues on Torizon OS 6.
I used the following branches for Torizon OS 7:
[submodule "linux"]
path = linux
url = git://git.toradex.com/linux-toradex.git
branch = toradex_6.6-2.0.x-imx
[submodule "device-trees"]
path = device-trees
url = git://git.toradex.com/device-tree-overlays.git
branch = toradex_6.6-2.0.x-imx
tcbuild.yaml file (for the Dahlia eval board):
