Hello.
After discovering the PE16 pin 37 at GPIO has R65, but no R28, I solder one there :)
Now when connect GND to pin 37, A64 poweroff, but reboot. I would like it remain off
Is there's something else to do to achieve a poweroff with PE16 ?
Thanks
No idea, it should be explained in AXP803 datasheet.
Did you keep the PWRON to GND all the time? If you release the GND connection the AXP803 is supposed to boot.
Hello, thanks for answer.
I soldered a 0603 1k (carefuly drifted) resistor on pad R28, near to R65, which is populated.
The situation is now power button acts more like a reset, than a power button.
It boots with no problem. If I press any, original pwron1 button or PE16 to gnd, system reboots, no shutdown. I'd like it to shutdown and stay off.
The resistor is still there, because is kind of tricky to put it on there. I sort of remember before I put that resistor, pressing pwron1 button shuts down the system and it remains off. Is that way right ?
Just remove the resistor you placed and use the PWRON1 button, hold it for few seconds and the board would turn off and won't boot back again. That is until you press and hold it again, then it will boot.
Hello. Thanks for your response.
Really I wanted to export that button to my outer box, that will be a container for my A64. So I can turn it on and off.
Well, by now I just removed the 1K resistor R28 and pressing the on board pwr01 button, the shutdown behavior returns.
Please any advice on getting this functionality working, will be appreciated.
Thanks
Why didn't you just solder wires to the pads of the reset button. Just add wire at each side of the button and add a second button at the box...
Measure between the pads of R28 of continuality and see if there is connection.
