bmd350 eval kit drawing 15uA in sys_poweroff after power cycle

[Joe F.]

Hello,

I'm measuring current at the Vbmd jumper for the BMD-350 Eval Board. I'm able to measure 0.9uA running this code:

1. in the boot immediately after programming
2. reboots after pressing wake up interrupt + sys_poweroff
3. reboots using the reset  button.

    ret = pm_device_action_run(cons, PM_DEVICE_ACTION_TURN_OFF);

    sys_poweroff();

However, after power cycling the board, i'm drawing 15uA through all those scenarios. I'm at a loss of how to fix this. Any recommendations is really appreciated!

Hello,

It may be the reason of SWD debugger not disconnected properly. When the device is in Debug interface mode, it draws additional current since it keeps a certain set of peripherals ON all the times. 

I can see you tried soft and hard reset and still a bit higher current.

We need a bit more information. Which application you are trying? It would be helpful to look at the application code.
