Just one quick question! Am I correct that in the case of CoreELEC 22.0-Piers on the Ugoos AM6B+, Dolby Vision FEL playback is no longer supported?

[image] Archttila: Dolby Vision FEL playback is no longer supported Really? Need to ask again and again? No, no FEL with CE-22 NO build.

I want to try get analog audio working on an agreed somewhat old Ugoos X3 Pro so I do $ git clone GitHub - CoreELEC/CoreELEC: A lightweight OS for KODI · GitHub $ cd CoreELEC/ $ git checkout -b 22.0-Piers_alpha3 22.0-Piers_alpha3 $ scripts/build linux That goes fine and I get sm1_s905x3_4g_1g…

[image] tasinofan: Question : How do I manage to do so i.e. to just rebuild the dtb? If all you are working with is device trees then just use device tree compiler dtc -I dts -O dtb -o sm1_s905x3_4g_1gbit.dtb sm1_s905x3_4g_1gbit.dts Full how to here: How to use the command 'dtc' (with examp…

@neqwdtkukwjaanti thanks for reply I had tried device tree compiler but maybe not exactly correct command line usage… :frowning: I got a compile error line#1 (both on original and new dts) So I then thought perhaps some target for $ scripts/build target # rebuild dtbs existed. I am now resta…

[image] tasinofan: Now I change sm1_s905x3_4g_1gbit.dts but if I next do $ scripts/build linux again, … nothing happens. After you have made your edit run rm -f build.CoreELEC-Amlogic-no.aarch64-22/.stamps/linux/build_target then scripts/build linux removing the stamps forces a rebuil…

[image] YadaYada: I don’t know what your entire dts edit looks like to know why dtc is failing. I think I see why, I made an assumption they had a full dts they were working with. Instead the only place it exists is from the linux source (on my end) build.CoreELEC-Amlogic-no.aarch64-22/bui…

[image] YadaYada: rm -f build.CoreELEC-Amlogic-no.aarch64-22/.stamps/linux/build_target this works! Thanks fwiw: Unfortunately I could not get analog audio to work and the Ugoos X3 bluetooth does not work either. In fact, the patch was a noop since amlogic_codec is set in coreelec_sm1_common…

What are you even talking about? I haven’t asked anything on this forum for about a year and a half. :slightly_smiling_face: I’d suggest you take a little break sometimes too… :wink:
