I took the original sources just for the device tree compilation, instructions from https://linux-sunxi.org/Mainline_Kernel_Howto
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git --depth=1 cd linux/ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig edit arch/arm/boot/dts/sun7i-a20-orangepi.dts compile ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4 dtbs copy arch/arm/boot/dts/sun7i-a20-orangepi.dtb to /boot/dtb/
 
the patch file has more than just phy-mode = "rgmii-id";, I guess you missed it?
 

see the patches https://github.com/armbian/build/pull/2750/commits/59797c3324e5f2db4a7727126a770049d274290c
 

If you report troubles with self build image not many people will listen. Self build images are officially not supported since they are build from a development environment, unknown upstream quality, nobody test features and anyway we can't afford dealing with "customers" in real time. Strictly speaking only digitally signed images are a subject of our interest. Limited with our private time! Even that is extremely hard and expensive (99% is our private cost which is not small at this level) to keep those cheap board operational and usable. We lost about 30-50h for this project in total every day.
 
 
Until someone will make things together properly and provide a PR, it won't. But we don't receive help even for simple things https://forum.armbian.com/forum/54-help-wanted/ we ask while current maintainers are totally overloaded. Wishlist is estimated on millions / years of development.
 
 
I see, It looks like we don't have them for A20  But everything else ... so you will need to edit DT by hand. It could also work fine via armbian-config -> system
 

  
 

- (backup of) boot scripts are packed in u-boot or bsp package
- this is not a bug but feature. In some cases legacy kernels needs boot loader that is incompatible with current modern kernel.
 

IIRC we have (had?) some bug related to A20 / LK5.10.y / HDMI out. Try build image from sources.

Those DTs are maintained upstream, but not sure if there were any changes for years. Some properties could also become obsolete in the meantime ... Also try this way: armbian-config -> system -> hardware and enable all USB ports.
 

Could be more than one reason:

- keeping wifi drivers nobody maintains aligned with modern kernel. Require constant rework - just few recent commits on the topic:

https://github.com/armbian/build/commit/03e4f604d3ee991183840ff7a3c0959be1e28637
- DT bits for Orangepi wifi are not present in Bananapi DT
 

Try not to associate question to persons. This is forum. People help if they can and have time ...
 

Kernel driver is present, but we don't have click and play experience. I don't deal with this.
