S32K314: after wakeup by gpio, cann`t boot normally

[Jingjing]

hello:

I encounter the problem that:

when enter standby, the current is 0.01A,then use gpio to wakeup the board, the current change to 0.05A, then stop, the board isn`t boot up.

I want to ask that:

1. if the ips need all enter standby, board can be wakeup normally?

2. may be what cause to this problem?

Hello @Jingjing,

Hard to say what could be wrong just from the short description.

Can you take a look at the examples in this thread:

Hello @Jingjing,

You enabled Sleep-on-exit, but in this case, the core goes to deep-sleep again once the wakeup ISR is complete.

Try without it.

These are functional examples.

[Jingjing]

these example cann`t run on my hardboard,I compare these configurations, i have already set what the demo config for wakeup, so i don`t know what is the cause for my hardboard cann`t wakeup from standby.

can give me some advice to confirm the cause?

Which version of the RTD drivers do you use?

I would recommend creating a new simple project and just testing the Standby mode wakeup without all the other modules you have in the current project. And only after it works on you HW, implement it in the project.

The increase power consumption in the Standby mode can be caused by the driving external loads on the pads. Please try to disable the padkeeping in the Standby mode.
