Orange Pi PC2 - H5 and DVB TV uHAT
Is it possible compile LibreELEC with DVB TV uHAT dtb?
Yes but currently there is no support for overlays yet, so you have to either compile image with additional patch yourself or modify DT by hand (decompile, change, recompile). Neither of these two options is straightforward...
I have an H3 board (BananaPi M2+) and I was wondering, will it run Kodi 18?
I know the Allwinner boards are a little temperamental and some only work with Kodi 19, but I saw an old forum with an Openelec image with Kodi 16, so I thought there might be a chance? Does anyone have any experience with this device? Will building LE 9.2 work for it?
BananaPi M2+ works very well with current nightly images but that means Kodi 19. Why would be Allwinner boards temperamental? LE 9.2 has extremely basic support for Allwinner SoCs and Cedrus driver not so good that it's now, so I wouldn't recommend 9.2 anyway. Why would you need Kodi 18? Python 2?
I just tried the latest nightly (2020/12/06) on my orange pi one plus a few minutes ago.
There seems to be a networking issue ( flashing lights on the ethernet port but no usable internet connection).
I also have problems with ethernet with the newest image (LibreELEC-A64.arm-9.80-nightly-20201208-8bfef13-pine64-lts.img.gz) on the Pine A64 LTS. An older image (20200311) works fine but has some other quirks.
Both networking issues will be fixed once Linux 5.10 PR is merged. If they are not, please report again.
