March 29, 20251 yr I did upgrade my NanoPi-R6C and see that there are no overlays in the linux-image-6.14.0-edge-rockchip64 Debian package; they were there in 6.14.0-rc4-edge-rockchip64 So there is no folder: /usr/lib/linux-image-6.14.0-edge-rockchip64/rockchip/overlay Is this on purpose or some mistake?
March 30, 20251 yr Author 2 hours ago, Werner said: dtb overlays are usually in /boot/dtb/rockchip/overlay Indeed they are copied or symlinked there from .deb package: linux-dtb-edge-rockchip64 But also that package does not include any overlays. I (re-)installed this linux-dtb-edge-rockchip64 package again now (trunk.313 instead of trunk.311 yesterday) and also that package lacks overlays. E.g. check with: dpkg -L linux-dtb-edge-rockchip64 | grep "rockchip/overlay" So even that there are 2 Armbian packages containing the same set of dtb+dtbo files, none of those 2 edge packages contains overlay files. So it seems something wrong in Armbian build, maybe only packaging, maybe even they are not build/compiled. This is actually a test for my Rock3A (or new/extra RK35xx still not purchased) to see if I can work with mainline kernels instead of vendor (6.1.99). Note that for 'vendor' the overlays are there. 'current' I don't know, I do not use it at the moment.
March 30, 20251 yr Author Solution Ran a build, it packs overlays: [🌱] Packaging linux-dtb [ rockchip64 linux-rockchip64-edge ] [🔨] [ 21M] /local/s0/armbuild/rock-3a/build/.tmp/work-efccbebe-0297-4492-8451-549f4047d14e/kernel_dest_install_dir-w5E9G/dtbs [🔨] └── [ 21M] rockchip [🔨] ├── [ 75K] overlay [🔨] │ ├── [1.9K] hinlink-h88k-240x135-lcd.dtbo [🔨] │ ├── [7.2K] README.rockchip-overlays [🔨] │ ├── [ 459] rk3308-b@1.3ghz.dtbo etc. /local/s0/armbuild/rock-3a/build/output/debs# dpkg --contents linux-image-edge-rockchip64_25.05.0-trunk_arm64__6.14.0-S38fe-D0000-P6158-C3a01H3d80-HK01ba-Vc222-B9bbb-R448a.deb | grep "rockchip/overlay" | grep README -rw-r--r-- root/root 7355 2025-03-30 11:34 ./usr/lib/linux-image-6.14.0-edge-rockchip64/rockchip/overlay/README.rockchip-overlays So my local build is fine; seems something wrong in the 'Armbian build cloud infrastucture', I don't know anything about that.

Its probably a "feature" of new kernel version that broke some mechanism. 21 minutes ago, eselarm said: seems something wrong in the 'Armbian build cloud infrastucture' Kernel 6.12.y is packed well so its something in the middle, corner case. I also don't know more then you.
March 30, 20251 yr Just like kernel features and drivers such overlays need to be developed to be shipped. So it is very likely that some/most/all overlays for various features are missing. If you need them, vendor kernel is the way to go for now.
