How to bring up the operating system on an armStone A9 without any additional displays, but just via LAN cable?
My network setup looks like this:
Details:
- PC (machine 1): Ubuntu 14.04 LTS / amd64
- ARM board (machine 2): Armstone A9

Do you mean that you want to wake the device up without anything else attached or do you want it simple to run "headless" when you turn it on? – Julian Knight – 2015-04-12T20:36:00.000
@JulianKnight Is it possible to unwrap OS via LAN cable on the device? Is there anything like presystem software to build up a system on the device, or something like presystem remote-desktop-viaLAN software, or display/commands-via-LAN access? The OS system is probably already on the SD card on the device, so maybe there is some LAN way to release it and set it without any additional displays? – cooba – 2015-04-13T09:42:15.177
If it is anything like a Raspberry Pi, you only need power to it. If it runs Linux as an OS, just set Linux to boot to the command line (e.g. not the desktop), nothing else is needed. If you want the OS to be off-platform, you would need PXE boot capabilities. No idea if your device has that I'm afraid. – Julian Knight – 2015-04-13T20:59:52.897
@JulianKnight Is it possible to set Linux to boot to the command line through LAN connection (without additional displays)? What kind of software is necessary to do it? – cooba – 2015-04-14T00:05:35.110
No additional software is needed, As root, edit
/etc/inittaband changeid:5:initdefault:toid:3:initdefault:. When you reboot, it will always go to the command line. – Julian Knight – 2015-04-14T10:20:36.947@JulianKnight To become a root on my system I do need a display attached to my ARM board, don't I? But I want to boot it up without any displays, so I'm asking whether it's possible just though LAN connection. – cooba – 2015-04-14T14:09:29.423
Depends if you already have SSH configured on it. To be brutal, you HAVE to have a screen & keyboard on it at least once to do an initial setup UNLESS it comes pre-configured with SSH so that you you can remotely connect. Once you have SSH, you no longer ever need to log in directly. Please do some reading on "headless" Linux configurations. – Julian Knight – 2015-04-14T15:33:51.203
@JulianKnight OK, that's helpful for me. Thank you. – cooba – 2015-04-14T20:45:35.377
