jernej,
So, I have done all the things from your link. I configured Git in my laptop Ubuntu and downloaded the LibreELEC, so it's in my Home folder now.
Then I have run: PROJECT=Allwinner ARCH=arm DEVICE=H3 scripts/create_addon pvr.iptvsimple, as you have told me and it began creating a build with PVR (I suppose) for very long time.
Now should I just make and image using PROJECT=Allwinner ARCH=arm DEVICE=H3 UBOOT_SYSTEM=orangepi-plus2e make image and that's it? Would I get an image with the PVR Simple add-on included, or what? Thanks again!!!
P.S. Or should I had to first compile an image using PROJECT=Allwinner ARCH=arm DEVICE=H3 UBOOT_SYSTEM=orangepi-plus2e make image and only then to compile an add-on using PROJECT=Allwinner ARCH=arm DEVICE=H3 scripts/create_addon pvr.iptvsimple ?
