Hi,

I am using OMAP 3530 EVK and wince 6.0 R3 and BSP_WINCE_ARM_A8_01_00_00_Source. I would like to turn off/shutdown EVK. When i try to turn oof using setsystempowerstate API the evk goes to suspend mode only and it resumes whwn we press the pwr key.

1) Is there support for shutdown in EVK? and how can i turn off the EVK?

2) if there is no support, how to shutdown EVK?

Waiting for your valuable reply. Thanking you in advance.

Regards,

princy

    If by shutdown you mean completely cutting off power -  AFAIK this is not possible to do from Software on the EVM.

    As Atul points out, there is no way of totally shutting down the EVM from software, as the power switch is manual and will always leave some minimal power supplies unless you manually switch it off. The best you can achieve to emulate a shutdown from software is to put the board to suspend mode (as you are already doing with the SetSystemPowerState API) and make sure no wake up source is enabled. This way the board will be in its lower power state (with the power switch being still on) and can only be woken up by resetting/power-cycling the board.
