I found myself working on a project where the source code was lost. The project uses a NanoPi that uses an Allwinner chip which is a 64-bit Aarch (ARM v8) architecture.

I've tried several decompilers but they didn't work, or wouldn't even compile. I looked at boomerang, Hopper, snowman, retdec, and reko. The ones that work wouldn't handle the architecture. The ghidra decompiler has been the only one that has proven useful. I haven't read enough about it to know how to save source code out of it but I can browse decompiled output which is at least the first step in reconstituting source code.
