I overcame that issue by running make with the following environment variable:
- USER_EXTRA_CFLAGS="-fno-stack-protector"
 
`USER_EXTRA_CFLAGS="-fno-stack-protector" make all`
 
This may help someone... 👍

I've just tried to reproduce the problem with a 15cm cable... It still happens easily.
 
In my case, I don't think it's related with power supply but I'll try to clear that out in the lab.
 
If it was,  it should happen consistently with several USB devices overloading the power supply with the 4 CPU cores at 100% each, which never occurs.

I brought a TTL adaptor from my company's lab and now I can confirm I'm having precisely the same problem described in the OP.
 
I also found out this thread, which can be useful for other to better understand this issue: https://github.com/longsleep/build-pine64-image/issues/51
 
As I doubt I have a problem with the power supply I'm using, for now I decided to test another USB cable.
After that, I'll make proper testings of all the components involved if I need it...

From Armbian perspective this is the main update on this subject: 
 
We are using some patches on top of mainline. Currently DT overlays are supported for H3 mainline (sun8i-dev) and A10, A20 mainline (sunxi-next) targets, but this has not reached the stable images yet.
