Hello!
Here is a little utility called PowerOff.dl3. By running this either from config.txt or the VSOS Shell you may turn the power off the VS1005 Development Board.
To use this program, copy PowerOff.dl3 to your VSOS system disk SYS/ directory.
As far as I have tested, it works, regardless of whether you have the USB-UART or USB cable(s) connected or not. Nevertheless, if you have a different experience, let us know in this thread.
Kind regards,
- Henrik

Re: PowerOff
Hello Vlsi team,
This driver file switch_off most of the things !
1.) I want to use this for my application, like if there is no activity on the board for suppose 5 mins then it should automatically go to sleep mode.
2.) And for awaking the board again, i want to use any button Like SW1, SW2 etc. (Because Power button restart the system, in place of starting the system were it left).
Please guide on this !
Thankyou

There's no such automatic functionality available. You need to build that into your application.vinayslone wrote: ↑Sun 2020-12-06 21:051.) I want to use this for my application, like if there is no activity on the board for suppose 5 mins then it should automatically go to sleep mode.
To get really low power consumption during sleep, you will need to switch power off and reboot again. You can store information about your application's state to the RTC RAM so that your application can reboot to the correct state.vinayslone wrote: ↑Sun 2020-12-06 21:052.)

Another possibility is to run the VS1005 at a slow clock rate to minimize power consumption, but never really switch it off. You need sufficient core, I/O and analog voltages so it will take a couple to a few milliamperes probably. Please see the thread about VS1005 power consumption at: viewtopic.php?t=1319

Re: PowerOff
Does this work for VS1010? I am trying to figure out how to power down on the VS1010 dev board
Re: PowerOff
The same principle applies to vs1010 - set external interfaces and GPIO's to power-off, switch to 1.0x clock, wait until the power button is released, then shut off the internal regulators and wait to lose the power. The poweroff solution hides some of the details by using some VS1005 ROM functions.
