How can I call an external command (as if I'd typed it at the Unix shell or Windows command prompt) from within a Python script?

The duties and mission writing work is extra tough to creating those papers. The high-quality and powerful writing is possible for the students at on-line. The call and content should be offering as certain. All forms of writing papers are providing to the college research for developing their writing papers.

Hi All,

I have tried compiling following component for Pine 64 1GB board (as instruction mentioned at https://github.com/apritzel/pine64)

uboot - (git://git.denx.de/u-boot.git master branch)
kernel -(https://github.com/apritzel/linux.git a64-v4 branch)
( command used to create uImage  "mkimage -A arm64 -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux kernel" -d arch/arm64/boot/Image uImage")
Uboot runs successfully but kernel loading  does not proceed and hangs at "Starting kernel ..." messages  

What I am trying to do is to boot board with NFS+tftp, but not able to proceed beyond uboot.

Detail logs are as follows

Hi Guys,

I have many search engine and finally I got this website light fastness tester machine in china. And this website is http://textileinstruments.net/pod_pro.as...Tester.asp so guys could you suggest me some better idea and more information about this light fastness tester machine?

Hi,

I have ubuntu installed, this version:

Hi,
i'd like to use my board (pine64+ with 1 gb) for some OpenCV...
I'm planning to capture short videos and analyze them using OpenCV.

I've read the posts on the camera module and from what I get, it seems a bit weak on capturing videos and such.
In comperison i'm looking at a simple webam ( almost the same price).

What do i get from using the camera module (except the compact size and free usb port..)

Thanks ahead.

Any chance we will ever see the BSP?

I would love to get my hands on the source with drivers no matter what shape it is in.

I am willing to work on it and smooth out some of the rough edges and contribute back to the community.
I am an embedded Microsoft MVP ready to help.
Lots of experience on other IoT Core platforms and toolchain.

I have a serrious issue. Got yesterday my new Pine 64 with 2 gb delivered .i Have no sound over HDMI nor Audio jack
Installed Android 7 
have tried the android 6 /Lollypop/and 5.1. with no result
Please Help:Thank you

I've been using my Pine64 to host my Plex and Transmission torrent server. Lately, I've noticed that the server only stays alive for ~1 day before becoming unresponsive (meaning I cannot SSH into it, but the power light remains on). I'm hoping someone here has an idea or suspicion for what's going on because I'm at a loss.


Hardware setup:

• Pine64 - 1GB board
  
  
• Externally powered USB 2.0 hub
  
  
• 1TB USB 3.0 Drive
  
  
• 2TB USB 3.0 Drive
  
• Heatsink on cpu
  

• Plex Media Server (Plex application data is on 1TB drive, media is on 2TB drive)
  
  
• Transmission daemon (writes to 1TB drive)
  
  
• PlexPy (monitoring)
  
  
• DynDNS (for easy-to-remember CNAME for Transmission + Plex)
  
  
• sshd
  

I installed Android 6.0 via the link in the wiki.

Android 6.0 Image (HDMI Video Output) Release 20170112 [ver 2.0.1]

Where do we log feedback/bugs?
