Information Console access withouth network or monitor.
Posted by: mypineme - 08-26-2016, 03:27 PM - Forum: POT modules - Replies (6)

This thread describes a successful connection providing a UART Serial Console on a Linux Host however, this should work on Windows and Mac. The PINE64 board used is a 2GB version (A64-DB-2B-Rev B 2016-02-25). The connection is provided by a USB To RS232 adapter purchased from eBay:
NOTE: you would need 3.3v USB To RS232 adapter, otherwise you may fry your PINE64!

The successful connection is made on the EXP connector:

    Connect the GND (it should be labeled on the USB Module Adapter) to Pin 6 or 9 of the EXP connector.
    Connect the RX (it should be labeled on the USB Module Adapter) to Pin 7 of the EXP connector.
    Connect the TX (it should be labeled on the USB Module Adapter) to Pin 8 of the EXP connector.

Plug the USB end into your Linux host. Find the tty that has been assigned to it by opening a terminal window and typing

Code:
$ dmesg
. The last group of messages will show you how Linux has mapped the USB module to the tty. In my case the output appears as:
Code:
[ 4806.188739] usb 3-1: new full-speed USB device number 6 using uhci_hcd
[ 4806.338823] usb 3-1: New USB device found, idVendor=1a86, idProduct=7523
[ 4806.338828] usb 3-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[ 4806.338831] usb 3-1: Product: USB2.0-Serial
[ 4806.341875] ch341 3-1:1.0: ch341-uart converter detected
[ 4806.354983] usb 3-1: ch341-uart converter now attached to ttyUSB0
What I'm looking for is:
Code:
[ 4806.354983] usb 3-1: ch341-uart converter now attached to ttyUSB0

The final line of the output indicates the USB Serial Device has been assigned to ttyUSB0 (/dev/ttyUSB0).
There are many ways to connect to serial using Linux OS, I will show you two method that I use.
Method one (terminal):
Code:
$ sudo screeen /dev/ttyUSB0 115200

Method two (UI):
you would still need to run it from terminal as sudo.
Code:
$ sudo gtkterm
1.) Go to Configuration->Port
2.) Select /dev/ttyUSB0 from Port drop down
2.)Change Baud Rate to 115200
3.) Then click OK

Boot the PINE64 and you should see output in the terminal window on your Linux host.


Lightbulb Perfect ABS Plastic Server Enclosure from Radio Shack
Posted by: MarkHaysHarris777 - 08-26-2016, 01:40 PM - Forum: Enclosures - Replies (14)

ABS Plastic Server Enclosure 15.24cmX10.16cmX5.08cm from Radio Shack

This classic Radio Shack ABS Plastic enclosure ( 6x4x2 inches ) is ideal for the pineA64 board, particularly for server applications. These boxes are being marketed by Radio Shack and others like EBay and Amazon. The enclosure is readily modifiable , but is the classic rugged Radio Shack quality ABS box hobbyists and amateurs have come to expect for years.

The box has the classic interchangeable plastic or aluminum base plate fastened by four rugged corner screws. The cabinet is ideally suited (size and shape) for the PineA64 board; with room left for mounting power supply filters, batteries and GPIO cabling, or even a fan.

If you need a ground plane , the aluminum bottom plate (or top plate!) is perfect; else if you need a non Gaussian enclosure the interchangeable ABS plastic bottom plate is also perfect. While I do plan to place my desk Pine board on display in one of Dustin's classy cases, my headless server boards need to be protected too... and this little box is a perfect enclosure.


  Touchscreen display mods

Hello all, 
I'm looking for some answers you may be able to help me with. I have a screen from a Kindle Fire HD7 and curious whether or not it can be adapted for use with my Pine+? 
I also have a smaller non touchscreen LCD from an old baby monitor that I would like to try. 
Any help would be most appreciated!

  Pine64_health.sh problem
Posted by: jl_678 - 08-25-2016, 06:57 PM - Forum: Linux on Pine A64(+) - Replies (3)

Hi,

I just noticed a problem with the above script and do not recall seeing this in the past. When I run it, I get the following:

debian@pine64:/usr/local/sbin$ sudo ./pine64_health.sh
CPU freq : 480.00 MHz
CPU count : 4
Governor : ondemand
Core voltage : 1.04 V
SOC Temp : 35 C
Cooling state : 0
cat: /sys/devices/soc.0/cpu_budget_cool.16/roomage: No such file or directory
Cooling limit :
debian@pine64:/usr/local/sbin$

Does anyone else see this? I am wondering if this could be related to the recent kernel update or if something else is going on.

Thank you!


Okay, so I figured this out. The path changed and the script is accessing the old one. The correct path is:

/sys/devices/soc.0/cpu_budget_cool.17/roomage

I am not sure why it changed.

Posted by: Severian - 08-25-2016, 06:52 PM - Forum: Enclosures - Replies (3)

I took an old desktop pc case I had, stripped it down and mounted my Pine64 in it. I stripped the power supply down to the external cord connector and switch, allows me to switch it on and of easily. Mounted a small cpu fan under the board for a little cooling, and left the original case fan. Wired in a power strip for the power supplies for the pine64, cooling fans and speaker power. Wired up the front usb ports to a usb plug for the pine so both front usb ports on the case work. Then mounted a speaker on the front of the case. Granted, I would have to remove the cover to swap out sd cards, but i'm primarily using it to learn ubuntu, so not an issue right now. Lol, takes up some space, but hey, it works.


   
   
   


  Android 5.1.1 TV (old-stable, no longer maintained)
Posted by: ayufan - 08-25-2016, 04:59 PM - Forum: Android on Pine A64(+) - Replies (194)

Hi,

The last couple of days I have been working on making our Pine A64 useful, at least in some way. It took some time, but progress is quite promising. Maybe someone would be interested in trying it out.


Features

- I can play Youtube videos and cast them from Phone or Browser,
- I can control Pine using my TV pilot (using HDMI CEC),
- The WiFi appears to not be connecting (but discovering) solved,
- I had troubles with working Bluetooth solved,
- 4K@30fps appears to be working,
- I can run Plex and cast videos using Plex app,
- I can use Android Remote on Mobile,
- I can use Spotify Connect,
- Google Play is not working after first update: this device is not supported, blabla solved,
- Standby over HDMI-CEC doesn't work, when TV sends a standby command and then Power On, Pine will not wake up (disable Auto standby on TV for now).

How to compile?

Tutorial how to compile sources is already written: https://github.com/ayufan-pine64/manifest. Skip only `extract-bsp` part since the kernel is already updated.

How to install?

Download compressed image from:
https://github.com/ayufan-pine64/android-5.1/releases

You can use RasPlex Installer to copy it to card, just point to downloaded image file:
http://www.rasplex.com/get-started/raspl...llers.html

There's a problem with DPI on the first boot. When you see a welcome screen you have to reboot Pine.

Troubleshooting

If someone decides to try this. Please post your `dmesg` log and `adb logcat`. You can connect with `adb` over IP address, like this: `adb connect IP`.

Create an issue here: https://github.com/ayufan-pine64/android-5.1/issues


List of my improvements

- rewrote HDMI CEC kernel driver for our 3.10 and pine64 longsleep sources: https://github.com/ayufan-pine64/linux-3.10 and https://github.com/ayufan-pine64/linux-pine64,
- write HDMI CEC hardware driver for Android: https://github.com/ayufan-pine64/device-...d/hdmi-cec
- configure tulip-chiphd to behave as Android TV: https://github.com/ayufan-pine64/device-..._chiphd.mk
- add 4K output for Android TV (you have to enable Developer options, then Developer Options -> General -> HDMI resolution and choose from 720p, 1080p, 4k@30fps), it even appears to be working on my 4K Dell screen: https://github.com/ayufan-pine64/package...TvSettings
- extend Android TV build: https://github.com/ayufan-pine64/proprie...google_atv
- make the build to behave as fugu to make Google Store to detect this system as only Android TV compatible
- disable IPv6 support to mitigate problems with Allwinner media player which doesn't support IPv6 when playing movies over network
- wrote Power Management module for Android, making this build a 15% faster then original,
- have fully reproducible builds and use CI to build Android images


  Adafruit 16x2 LCD doesn't turn on with Pine64
Posted by: mypineme - 08-25-2016, 10:16 AM - Forum: POT modules - Replies (13)

Hi all,
I got my self an Adafruit 16x2 LCD display, put it all together, plugged it in and it won't turn on, not even the backlight. I was wondering if someone had experience with the LCD and don't mind helping me.

I got two of the PINE64 while back for my OBDII project as well as for a another project for the kitchen and its been on the shelf for a while. I have no experience with GPIOs or I2C and recently got socked in to experiment with it. From what I read, PINE64 pins are same as it on Raspberry Pi and I though that the LCD would be compatible with PINE64. Aperintly it's not the case. If I can get some guidance on how to make it work with PINE64, that would be awesome.

  UVC Support
Posted by: Thois - 08-25-2016, 08:13 AM - Forum: Remix OS - Replies (1)

I saw that UVC support is now added to the latest release, however, it doesn't seem to work on my board with the device I have. I have the following device attached: http://www.oupree.com/UVC-USB-CVBS-RAC-A...ndows.html

It seems to recognize the device only there is no image being displayed. 

I have an ubuntu installation on a Raspberry Pi 2 that works with it.

Also, the Camera Application is gone?

I have the 2GB Board
