I have the TV Box T95z Plus, 2gb ram and 16gb rom. I also tried several dtb.img and armbian doesn't work.
Try with:
Armbian_20.02.0-rc1.037_Aml-s9xxx_bionic_current_5.5.0-rc6_desktop_20200205.img
Armbian_20.02.0-rc1.038_Aml-s9xxx_eoan_current_5.5.0-rc6_desktop_20200205.img
And neither of them made it work.
Where can I download:
Armbian_5.90_Aml-s905_Ubuntu_bionic_default_5.1.0_desktop_20190701
You @amirul say that worked well for you.
