[...]

if SDPIF only POT board is a popular request, we will consider.

You will need:
Hardware:
1)     Usb type c cable, if you don’t have a type c cable you can also use an adapter
 
Software:
1)     Drivers if you hadn’t installed already:
files.pine64.org/doc/rock64/tools/DriverAssitant_v4.5.zip
2)     ADB files (platform tools) from Domo:
Android 7.1:
https://forum.pine64.org/showthread.php?tid=6683
Android 8.1:
https://forum.pine64.org/showthread.php?tid=6684
 
Ok let’s start:
 
1)     Go to settings/about tablet and tap build number at the end of the menu 7 times, this enables developer options on settings
2)     Verify that usb debugging is enabled on settings/developer options, if it’s on turn off and turn on again
3)     Restart device, wait for it to start…
4)     Connect usb to type c cable (adb only works on the usb type c port)
5)     Go to folder where you downloaded your Platform Tools, hold down the shift key and right click in a white portion inside the explorer window of the platform tools directory while still holding the shift key, select open command window here, wait for screen to open.
6)     Type:
 
Adb devices
 
It will start running deamon and do device recognition, if you had already opened adb it will only show available devices, if device does not show verify you have usb debugging enabled and restart again and you have connected usb type c to your computer, not all cables will work if you repeat process and device is not recognized change cable, still not showing try in another usb port on your computer.
7)     Go to Domo guide that is the same as your android version

https://forum.pine64.org/showthread.php?tid=6684
 
Copy paste commands in the same order as Domo instructions.
Copy paste without the ./ at the start of every command
Some commands will auto run if they don’t press enter after pasting
Remember to also run last 2 commands in adb shell after you have restarted device
 
That’s it, quick and easy, if you have questions comment bellow
 
Thanks Domo for sharing platform tools.

Hello

Can anyone tell me if a USB Y cable is enough to power a USB HDD ?
I was thinking about this kind of cable.

Regards.

Hello,

For those not following Debian development Buster (Debian 10) is now in deep freeze and will most likely be released in the following months.

I have been running it on a Pine64+ for the past months and it's quite usable for me.

Works for me:

• HDMI video output at 1920x1080 (tested console only, most likely framebuffer)
  
• USB (both ports)
  
• Ethernet at GBit speeds
  
• Watchdog (i.e. the logs show it is being enabled)
  

• slightly unstable, apparently more so when (lots) of USB stuff connected to it
  
• occasional clock jumps to the future (95 years?)
  

Hello,

As a Debian purist I wrote a small script to build a Debian image for my Pine64+ with absolutely minimal (and optional) customization.

https://salsa.debian.org/amp-guest/pine6...buildimage

In order to use the script you should read it first, but this is a good idea anyway with random scripts from the internet that must be run as root. In any case, if running it will join your pine64 to a botnet, destroy your data and/or hardware, set your house on fire, etc. I will not assume any responsibility. Use at your own risk!

At the moment I have no intention to publish any images as I believe one should build it's own (hence the motivation to write this script).

It's been a while since I used the script, but I think I was able to use a Stretch image (most likely the mainline Stretch image created by CallMeFoxie https://forum.pine64.org/showthread.php?tid=4931) to build a usable pure Debian Buster image, which I have been using since.


In case you are not following Debian development, Buster is now in deep freeze, which means it's quite close to the final version that will be released sometime in the following months.

I'm sure the script can be improved in various ways, including due to my modest scripting skills. Patches or Merge Requests on Debian's Salsa are welcome, provided they preserve the spirit: pure Debian with minimal (and preferably optional) customization.

Enjoy

Sorry for the weird thread subject but I'm not able to summarize better this behavior.

Scenario:
Pinebook 14" with default Ubuntu 16.04 (same shipped with the pinebook itself, just updated with apt + pine* scripts for uboot and kernel)

Problem:
Sometimes when powered off it cannot correctly power back on in a useful state since, even if the system is running, the screen is black (may lit up but no X session is there)

How to replicate:
Use the pinebook with AC adapter plugged in (charging), power it off, unplug the AC adapter, power back on --> black screen of death
Use the pinebook with battery, power it off, plug the AC adapter in, power back on --> black screen again

How to "workaround":
Just randomly powering it off and on again with AC adapter in until I get the "pinebook splashscreen" --> at this point boots fine

Tried different OSes:
Yes same thing on a SD card installed OS, or even worse --> with that never gets to a working X session (boots and does all stuff lilke expanding the ext4 partition) but screen just flashes in backlit black for 2 times and never comes along  (tried this image as last one: https://osdn.net/projects/manjaro-arm/st...03.img.xz/)
Sometimes I've successfully used a plain vanilla console-based armbian to try to recover a "always in black screen mode" (I discovered that I had ext4 to be checked due to my poweroff/on to restore a usable screen).

Battery state:

It's OK. It can stand many hours of work, and voltages are fine, charges regularly (if we exclude the black screen issue)

Image flashing issues:

I dont' think so, really, checked the sums, flashed with different sdcarcs and different methods  (dd with conv=fsync, etcher, name it... I do this stuff on a daily basis so at least here it's not a place to check for possible issues I think).


that said...


Any clues any of you mighty piners?

I suspect my pinebook is just faulty, but maybe I'm getting something wrong or we can discover something potentially useful for others users as well.
