[Android] Shutdown Button in tiny6410

Dnte
i have installed Android without no problem, but i can't shutdown the
system, only with the on/off switch. Where is the shutdown button in
tiny6410?

There is no shutdown built into the hardware. Power off is the only option.


I have this concern myself as I don't want to just power off but instead
select a power off option so I have worked on an external solution for
this.

I have designed (but not yet tested this software wise - hardware wise it
works great) a hardware ON/OFF solution using an LTC2954CTS8-1 which can be
used to power ON and OFF the device. The PWR INT signal is fed to the GPIO
pins. You hold in the button for a preset time (programmable by capacitor)
and it then sends a power up signal to the power supply. The device then
powers up and have to then hold an IO pin high to keep the supply active.

When you press and hold the button for a longer time, say 5 seconds, it
sends a PWR/INT signal to the CPU and you then need to detect this in the
OS somewhere and use this to perform a shutdown and pull the KILL line LOW,
this will then switch off the power supply.

The GPIO part I have not yet worked out but it is on my list of things to
do as I need this capability.

It also works as a failsafe when the OS has crashed by holding the button
in for about 15 seconds it will do power off without any KILL input
control.

Hope this helps.
