connect lipo battery to euler bus

[MarkHaysHarris777]

So there is definitely  something odd going on here... can you confirm if this is with the pine64 on or off, how it's powered, and which you're using? I'm starting to wonder if the PMIC on this board is a bit flaky... as there doesn't seem to be any good reason for it to be running so. Then again, datasheet isn't the best on some points - it doesn't detail what the charge 'smarts' of the PMIC is, if this one has any at all. It seems to indicate it only follows a CC/CV profile, with over-voltage/over-temp protection.

hi, I am presently running my Android batt to the ground ... then I'll start a change cycle and see what I can see by looking in sysfs. 

I can do that same thing for my debian build too, as far as that goes.

I'm sorry, I'll repeat the question: Can you confirm if this is with the pine64 on or off, how it's powered, and which distro you're using?

I gather from you you just said that this might be on Android... is that correct? This would explain a lot of things (specifically, why registers might have been reconfigured from their defaults).

I have three systems on battery:  (1) debian mate  (2) ubuntu mate  (3)  Android 7 ; special hardware

This is with the Pine board 'ON';  specifically, I have never charged my pine boards with them off.  To say is concisely, they have always been 'ON'. All of my boards are powered with 2.5A adapters @ 5v with passive low-pass filtering and connected exclusively via the euler bus at pin(4 5v+) and pin(6 ground).

Again my Android system is consistent with my debian and ubuntu system(s). They are using essentially the same kernel and almost the same hardware.  Although my special hardware is configured differently, all of the components are the same. All three systems use the same PMIC; AXP803  

Later tonight I will be able to put them into charge cycle (they're still running all day on batt) and then I can see what the sysfs system says about currents and voltate; also temps.
