Thanks. Can we re-efuse / enable it?
No, itās 1x programmable memory. Amlogic should be given a little credit

sometimes stupidity can be adorable.
But we can ignore it details here.
Can which dv capabilities be determined? i.e., profiles, cmv2.9 vs cmv4.0, FEL vs MEL?
You makemkv to open movie file you will see it is mel or fel, dont know about cm
I donāt know anything for certain so the less I say, the better, because thereās a good chance it will be wrong.
Iām very sceptical that Amlogic has different variations of the same SOC with different DV features. I think itās either the SOC has DV support or it doesnāt. The Cube (s922z) for example can play FEL, but Amazon doesnāt list it as supported. It doesnāt make sense they would pay extra for a feature that isnāt available in FireOS.
I donāt know about the cause of the differences in DV options (FEL, cmv4.0) between different Amlogic SOC famlies. SC2 SOCs are using kernel 5.4 with updated amlogic source that has lots of changes. Weāll have to wait to see what the CE Team can do. Or maybe there is a SC2 hardware limitation, IDK.
Could someone with a working setup please enable debug logging in CoreELEC, enable debug_dolby with this:
echo 0xFFFF > /sys/module/amdolby_vision/parameters/debug_dolby
and post a dmesg log that plays a DV file?
edit: in tv-led mode
I get green screen with hdr logo on my gs king x: https://paste.coreelec.org/3rZM6Q
From here this
The reason for the green screen is that when you send the AVI Infoframe to the display to expect a YCbCr signal, PGenerator may still be sending RGB. When a display sees a mismatch like this, you will see a green screen. In fact, you can see this in reverse too, when a display is expecting to receive RGB but in fact receives YCbCr, the screen would be magenta
may help in diagnosing green / magenta screens and flashes that are seen when switching hdmi modes.
Hey Guys, just got my Ugoos AM6B+ and trying to follow posts above as to which CE version to install. Assume 20.5 over 21 for now? Is 21.0-Omega_rc2 generic okay as well?
nm 
ā¦ installed 21.0-Omega_rc2 generic and DV is a success!

Thank you. Not a biggieā¦ performance is pretty snappy using a mSD card, but wanted snappier with eMMc install 
.
Use the dual boot option

Thanks for that suggestion. I need to read up on how to go to/from Android OS to CE with dual boot (with both installed to eMMc). Never done it before.
Reboot from nand in coreelec power menu will reboot to android. Coreelec will have priority from cold coot .

Is that officially supported? The dolby vision post says installation to emmc isnāt supported.
You can install on the emmc, but I would suggest using the dual-boot option.

The script only lets you install in dual boot mode.
