Hi,

I have just plug in an old sound amp that i had but in order to make it work i always need to disconnect the minijack, and then connect it again. I read somewhere in the forum that soldering http://forum.pine64.org/attachment.php?aid=310 between pin 4 and pin 3 a switch could make it, but it looks messy. Any other idea?

I was investigating why the power button does not always work to turn the Pine back on (shuts down after 5 seconds) after a shutdown with no power cycle.

It seems to work reliably with a battery connected though. After comparing the boot logs I think I found the issue, but need some input on how to fix this,
probably in the ATF or by making sure the AXP803 is in the right state after a shutdown with power-off.

Boot log differences: https://www.diffchecker.com/ZVbSo0ap (Left column is cold boot from power cycle, Right column is button triggered boot after a previous shutdown)

1.) On a cold boot the AXP detects correctly that there is no battery ( see lines 16, 38 in the diff )

no battery, limit to dc  vs. normal dc exist, limit to dc

2.) A bit later in the startup this leads to (see line 117ff)

no battery exist vs. PowerBus = 2(0: not exist 1:vBus 2:acBus 3:vBus&acBus) Battery Voltage=0, Ratio=0 key trigger battery low power and vol with dc or ac, should charge longer

3.) And in the right case, the system gets switched off (see line 129)

[ 5.742]power off

So what basically happens is, that on a cold boot the AXP properly detects that there is no battery and so no issues with the battery voltage... after a shutdown without a power-cycle the AXP seems to come back in a state where it has a battery detected (even if there is none) and the low battery voltage / charge level triggers a power-off....

I have been installed some IM applications on my PC which were LINE, ZALO and Viber.
Actually, I wanna back-up my chat history regularly such as monthly or weekly on my PC (without using a smart phone).
I have tried to do at LINE, however I just can back-up for some lines, it means that I cannot back-up for complete my chat history. Further, it have to do at each user. So if I have 100 friends at my friend list so that I have to back-up 100 times for clicking "save chat history".
Then, after I installed ZALO and VIBER, the PC has created automatically the folder at C:\Users\PC ABC\Documents\Wechat Files\abcde and C:\Users\PC ABC\Documents\ViberDownloads. However, both folder don't have chat history that I wanted.
abcde means name of wechat's user and PC ABC is the name of PC.

Please help me out to find out the chat history for these IM messengers.
For your information, I run these IM on Windows 7 that running over VMware Player. My host OS is Windows 7.
Any suggestion would be appreciated. Thanks.

I've been trying to get REMix OS to work for me, but it seems I have 2 issues:
1) I cannot enter my google credentials
2) If I wait a few minutes the screen goes blank and cannot do anything.

Any suggestions?

Hi.

Just realized that the Z wave module is connected to the full GPIO
Is there anyway you still could use any GPIO pins (for input / output) when the Z wave module is connected?
Is it using all of the pins ?

Also very disappointed that the Z wave module makes it impossible to use the Pine64 case (lid wont fit)...

regards,
bang

I would like to design a POT for the PINE64 that requires a lot of I/O. For example, I would like to design a board that has 4 stereo (or even 8) channels of high-quality audio output. What resources of the PINE64[+] would be appropriate for this endeavor? Can some of the existing interfaces (like display or camera) be re-purposed, and is there information available about how to do this?

Hi pine experts,

Please help me in choosing the database for my project which i am doing in pine 64. Please suggest me a lightweight database to run PHP 5 other than mysql. Any suggestion is welcome.

Let's discuss it here.

Does anyone tried to run Android Things on PINE64?

Hey, 
I instelled the Android 6.0 TV from the this link.
I tryed to insert analog output and it doesn't work, anybody have any idea why?

Just as a suggestion, I was thinking we should have a dedicated forum or subforum for guides and tutorials related to the PINE64.
