we did try to use A64 images from the Pine64 or the BananaPi M64 with the NanoPi A64.
The last times we did that with less success - OK Sytem is running but Network/Sound has to added via USB.
No suppport for the onboard devices
But today a user did wrote that - with the actual stable Pine64-image ( Armbian_5.69_Pine64_Debian_stretch_next_4.19.13 )
WiFi is us
For me it does work, but I dont know if @Hannes Worst did had success
Here are the "warnings" while decompiling the .dtb to .dts (see attachment) :
