What's the 4.xx kernel you use in your images?
In the last images used by the kernel 4.20.
I can boot LE with the nexus-a1 dtb, that I used a while ago with Armbian and kernel 4.19.0 where I managed to get ethernet connection up
Have you tried all the DTB options from the "gxm*" group ?
I feel that here there is a great level of difficulty to test your image
Reading the topic I realized that dozens of people just like they did not succeed!
You are mistaken, the process of running these versions from external media is very simple. Download. Unpack. Write to external media. Edit " uEnv.ini", specify the desired option dtb (this item is executed if the system does not start with the default option, if it starts, you do not need to change). If the TV box has previously activated universal multi-boot, you can immediately try to start. If you have not previously activated universal multiboot, you need to activate it. For those who want to install LE in eMMC, it is necessary to update the multi-boot using the recorded image. Please note, if you do not know exactly which multi-boot option is used (activated it earlier from other media), I recommend to re-activate using this image. The new version of multi-boot is compatible with previous LE images. That is, after activating the new version, you will be able to run new and old versions of LE. For correct operation the remote control also requires its setting (description how to do it earlier in this thread).
For people with S905 processors this topic has a lesser degree of difficulty. CvH
LibreELEC 9.0 builds for S905 (semi official)
THE referenced Le images are based on the old 3.14 kernel. I don't use that kernel anymore. All my images now use only the new kernel 4.x (might be an exception for S812\S805 to release the base of support in the mainstream kernel). So this is a different system, with different behavior (and the prospect). In the near future, the 3.14 kernel will no longer work with new versions of KODI and all versions that are based on the old kernel will not be able to work with new versions of KODI.
For all.
Test images LE (s905) (S912) 20190121_test_dvb were released with the addition of alpha version of DVB drivers (from ALF1). For those who have the opportunity to test them on DVB, please write the test results.
