Current iMX6 images support the dual-lite and quad versions of the following boards:
Installation is done by writing the LibreELEC *.img file to an SD card. The boards have internal hardware identifiers so there is no need to edit
extlinux.conf on the card. Selection of the correct dtb for the device is handled internally within u-boot.
NOTE - It is not possible to update from older LibreELEC or OpenELEC imx6.arm images to LE 10.0 as the boot configuration for LE 10.0 is different and older kernels do not support zstd compression. If you attempt an upgrade the boot configuration of the old installation will be broken. You are advised to clean install LE 10.0 and manually restore sources and library DB files. Backups can be taken and restored, but as there is now a long time gap since LE 8.2.5 (and OE 8.0.x) it is best to start over with a clean system.
