Hi,
I have recently bought a rev E A20 Som. Burned a mainline bionic 5.2.20 to an SD. At first start, halted device at U-boot level, typed olinuxino and selected A20 SOM 8gb as my hardware. Device booted but under /boot/dtb/overlay folder, only sun5i-a13* prefixed dtb files are present. Under /boot/armbianEnv.txt, overlay prefix is assigned as sun7i-a20. My question is, any possibility that olinuxino configurator creates wrong device tree for my a20? Or am I missing something?
Thanks in advance!
That sounds like u-boot knows more than the bionic kernel/dt stuff.
Is that bionic specifically supported by Olimex? If not, how about using one of their builds?
(Or, I suppose, report the problem to bionic.)
