hello,
I'm testing the latest (kernel 4.5) jessie server vanilla on a Olimex Lime2.
If a battery is connected to the board and the power plugged in, the board start by itself !
I would like to change this behavior, is there any file to tweak ?
Thanks
Did you manage to resolve the issue? I'd appreciate any instructions cause I'm experiencing troubles here too.
On A20/AXP209 boards default behaviour is that when AXP209 (the power management unit) detects voltage/amperage provided through DC-IN is sufficient then the board starts immediately. When you provide power through (Mini) USB or battery you would need to press the power button.
So there's nothing to tweak, your only solution would be to use the USB OTG port to provide power to the board (be careful to choose an USB cable with low gauge ratings -- 20 AWG would be the best since otherwise voltage drops might occur under load!)
Have you found a solution to this problem yet? It would be of great help if you could share the same.
