Sleep current for Pinebook or other Pine A64 based boards - xbing6 - 07-01-2018

Hi, any idea what is the sleep current for Pinebook or other Pine A64 boards?

Is it possible to get sleep current to as low as like <2mA?

Thanks.

Idle or actual sleep / off current? I'm pretty sure the pine64 was higher than 2ma when it was 'off' as the PMIC is still powered, etc. I should be able to test it easily enough once I know what you're after.

Thanks for your reply.

What I am referring to is: when system is suspended (can be waked up by power button) I'd think only below are working:
- RAM is in self-refresh mode
- wakeup circuit is working (wake up by power button)
- RTC circuit is working
- PMIC provides small current for above circuits
- Touch panel is not a wakeup source.

I used to work on TI OMAP chips + LPDDR2, we achieve <2mA suspend current.

Any idea what is the suspend current (or sleep current)?

I think that on Pinebook we were not disabling some sound components due to lack of unsuspending.
The commit in question: https://github.com/ayufan-pine64/linux-pine64/commit/741e917b3e74d9a150b489e18cdd9798c6fa1194#diff-0b8263d341de01f741e4deadfb18f9eb. It is likely that it has serious impact on higher suspend current.
