guys you are doing OK but provide the base and lack of documentation are two different matters.
Here, as example,
a better post with a complete script to at least create that SD card you mention in the installation.
I've created myself a reduced version of that script to drop the second part but still create a generic A10 bash able to format an SD that works. I might post it later on but I have the feeling it won't be welcome here.
Anway, right now in ssh, it works like a charm, thank you.
PS thanks for the highlight I've never put on my initial post ... very ... well ... you know, that wasn't me, WTF!
