  Fuse in the AC power line?
Posted by: cr2016 - 10-01-2016, 04:30 PM - Forum: DC Power In - Replies (3)

Hi,

I got an AC power socket with a fuse holder and was wondering which value I could use for the fuse...

According to the wiki page the power consumption is 2.5W and the pine should work at less than 1A @ 5V (http://forum.pine64.org/showthread.php?t...0#pid12060).
Using I=P/V we get something like 10/25mA for 220/100V. Would a 100mA fuse be reasonable?

Or, if someone is having a fuse in the AC power line, which value is it?

Thanks.

For several weeks I could not post here..., I registered with email of gmx.com and the email vertification never gets sent, so I had to register again and use gmail.com.

Shouldn't this be corrected?

is there a way to delete my old account completely?


  kodi install on A64, 2GB
Posted by: gychang49 - 10-01-2016, 02:35 PM - Forum: General Discussion on PINE A64(+) - Replies (1)

I have been disappointed with using Remix about 2 months ago and have not touched the board.

Having given up on basic general web use, I am considering using the board mainly for Kodi install.

1.  do I need to install linux, remix, android first?
2.  would like recommendation on which distro and how to get the most functionally useful kodi install from actual user.

thanks in advance.


  Unable to start Pine
Posted by: Topgun505 - 10-01-2016, 11:58 AM - Forum: Ubuntu - Replies (16)

So I have a 2GB Pine.  

I downloaded the Ubuntu file
xubuntu-xenial-mate-20160528-longsleep-pine64-8GB.img

I use the Etcher program to transfer the file to a 128GB class 10 micro SD card and it appears to install but when it goes to validate it hangs at 99% and never finishes.  If I look at the card through windows it appears to have written a number of files to the card.  

I tried putting the card in to the Pine and boot it up (using a USB mouse and keyboard plugged in, and using the AC adapter that came with the Pine) ... and plugged in to a 24" monitor with a HDMI cable.  

I get absolutely nothing on the screen, no BIOS of any sort, no indication it is trying to boot from the SD card.  Nothing.

Suggestions?


  zwave module not available
Posted by: eric - 10-01-2016, 08:28 AM - Forum: openHAB - Replies (4)

Hi, 

I'm using the pine64_openhab_20160915_8GB.img image with the zwave module and adapter for the PI2 GPIO header but it seems as if the zwave module is not detected. The module should turn up as /dev/ttyS2 but from syslog all I get is:

Sep 24 07:57:58 openhab kernel: [    8.285353] uart2: ttyS2 at MMIO 0x1c28800 (irq = 34) is a SUNXI

And then in openhab.log:

Code:

Most likely because it is read-only.' - reverting configuration changes on thing 'zwave:serial_zstick:board'.


Any ideas on what could be wrong?

  How do I change the default sound card?
Posted by: zirconx - 10-01-2016, 07:18 AM - Forum: Linux on Pine A64(+) - Replies (2)

I would like to change the default audio to the headphone jack. I am running dietPi (no gui/de).  I know I can change the alsa default card with an environment variable or asound.conf, but I think that only affects alsa utilities. I'm also using sox, so I just want to change the default (first) card at the OS level.  Actually I could settle for getting sox to pick up a different card by default but I have not been successful in that.

So I think I need to create a file in /etc/modprobe.d, with lines like 


Quote:options sunxi_sndcodec index=0
options sunxi_codec index=1

I also tried reversing them:
Quote:options sunxi_codec index=0
options sunxi_sndcodec index=1

but it's not working. The hdmi output is always listed as the first card.


Code:
root@DietPi:~# cat /proc/asound/cards
 0 [sndhdmi        ]: sndhdmi - sndhdmi
                      sndhdmi
 1 [audiocodec     ]: audiocodec - audiocodec
                      audiocodec

I'm just guessing at the driver names based on lsmod. Any ideas? Thanks.

here's the output of lsmod.

Photo 3D Printed Brick case
Posted by: harlandraka - 10-01-2016, 05:08 AM - Forum: Enclosures - Replies (1)

Hi all,

I wanted to create an easy to mount and nice looking case, so here it is.

It's 3D printable and is made with a box, a sliding element and a single screw to hold all together.

This case works but is still under development, I'm thinking about adding some holes for cooling fans.

I hope you'll like it!
Let me know what you think of it, any suggestion will be highly appreciated Smile

  apt-cache for all your shopping needs!
Posted by: tampadave - 09-30-2016, 02:19 PM - Forum: Ubuntu - Replies (2)

Hello all.

apt-cache is the tool I use to look for packages that are available for my build.  In this case, ubuntu 16.04LTS on arm64.  

apt-cache does not require sudo, and is good to identify the actual package name for whatever program you're looking for, and if there is none, you'll find that out too.  Mind you, this is for packages, not all possible projects or source code.  Packages are normally software products that work, are packaged, on this distribution, and are popular or essential enough to merit their inclusion in the package database (atp-cache).


Code:
apt-cache stats
will show you the current status of your apt-cache database.


Code:
apt-cache showpkg <package_name_here>
 will give you an idea of what would be installed, including dependencies, were you to install the package from that package name.  Which begs the question: "how do I learn the package name for the package I want to install?"  Good question!


Code:
apt-cache search <regex_term>
 will return a list of packages that include that search term.  You can grep it further, or just read through it to find your package name.  Lots of times, I'm off just a little in the spelling of the package name (grrr...) and this lets me find out what IT calls it.

There are more commands for apt-cache, and man apt-cache will get you the manual page for this very handy tool.  apt-cache search and apt-cache showpkg have been indispensable to my learning this new platform.  Use them and you will see.

Oh, and as is usually the case, all of these commands are from bash (the Bourne Again Shell).
