Why crystal orb doesn’t work,well,how to get those logs,BTW I am using x5mpro dtb.Tried other dtb,didnt work.

Useless data.

What about WiFi, BT, ethernet? Does it work? What else is not working.

Hello sir,I played few DV files,DV Profile 7 displayed as HDR,DV Sails sample is displayed in wrong colours.

With x5mpro DTB coreelec boots,I tried other x5m dtb files and system didnt boot,ethernet doesn’t work,but wifi does.

Hope this log helps:

Bluetooth works I guess.

DV Fel is displayed as HDR.

Maybe the x5mpro dtb can be modified to enable DV support? Overall system is working.

CAMLCodec::OpenDecoder Amlogic device does not support DV, DV is enabled by user, display does support DV, DV system is disabled

Yeah,I tried 4 DTB files for x5m devices,only one got me working is ugoos x5mpro dtb,so I guess probably the DV is disabled in stock DTB,can you modify,enable DV and re-upload dtb file so I could give it a try?

so,any thoughts,what could be done,to enable DV,I can provide more logs if necessary.

Copy dovi.ko so not the internal is used. I guess it’s encrypted.

I copied dovi.ko to root folder on usb drive and did full clean ce install,same issue,no dv output.

Is it really so hard to post logs?

After fresh boot

dmesg | paste
journalctl -l | paste

I’ll give it a try.

Ugh,I tried to get proper logs as you suggested,anyway thread is locked.

Again only half…

Thread locked - again because of useless information - until support is possible.

Hold up,wait a minute,I tested raw cpu performance from both devicec, SK4 has better cpu score than AM9,AM9 Has better GPU score and it utilizes 64bit android.

You can see test here if you’re interested:

Also one thing,that on first stock firmware,there were no option to set AM9 to max performace mode while test was done,but probably it can’t affect total score that much.

Also if you look at antutu score,the Am9 is not that far ahead from SK4.

Both are good devices,one has 64bit os,gigabit lan but no DV,other doesn’t have gigabit lan and only 32bit android,but has DV support.
