Run Neo-EmuELEC-H3 on sunvell r69 #52

Hi, is there any possibility to run this emuELEC for H3 on a sunvell r69?

In the bootloader.zip you published there's plenty of different orangePi boards but not for this TV box having a H2+ which in the end is 90% a H3.

I've tried converting to binary the r69 fex file from old armbian at https://github.com/armbian/build/blob/v19.08/config/fex/sunvell-r69.fex using fex2bin from sunxi-tools and copying it to the SD as script.bin with no luck

If not on your personal roadmap, I don't mind trying to support it myself but I may need some instructions on where to start from.

Thanks

I think you need a uboot too. see https://github.com/asakous/Neo-EmuELEC-H3/blob/master/scripts/mkimage line 230

Simple way is to try ready script.bin from RetroOrangepi or H3Droid or Armbian. Just replace script.bin in Neo-Emuelec sdcard. See attachements ROPI_sunvell.zip h3droid-sunvell.zip armbian-sunvell-r69.zip

Hard way is to unpack genuine Android image, find _sysconfig.fex open it and compare every parameter with Neo-Emuelec script.fex or open script.fex from Armbian, ROPI, H3Droid and compare with Neo-emuelec script.fex First of all see chapter [dvfs_table] - CPU voltage-frequency table configuration and [gpu_dvfs_table] - GPU voltage-frequency table configuration
