iamdrq Posted September 1, 2022 Posted September 1, 2022 root@nanopct4:/boot/overlay-user# armbian-add-overlay lcd-mipi-opi4.dts Armbian is not installed properly. Missing armbian-release or armbianEnv.txt I found 22.08 using extlinux.conf instead of the legacy set of boot.scr + text files. That will miss overlay function when using extlinux ?

iamdrq Posted September 1, 2022 Author Posted September 1, 2022 Yes, This way very cool that can load overlay on running system. But it reboot loosed and I hope overlay on boot
balbes150 Posted September 2, 2022 Posted September 2, 2022 IMHO Overlay is a bad practice that can be used only in cases where it is not possible to change the DTB used (for example, the system is written to a medium that operates in read-only mode and it is not possible to replace the DTB with another one). In other cases, the DTS source code is used and the necessary fragment is added/changed to it and a new DTB is assembled, or, if there are no sources, use the DTB to DTS conversion utility, add \ change, and reverse conversion to DTB.
