Question Controlling CPU frequency - no 2GHz?
Posted by: jimsurvak - 10-26-2020, 05:44 PM - Forum: General Discussion on Pinebook Pro - Replies (14)

Hello Pine64 community!
I've been reasonably happy with my PbP since receiving it early this year. However, I was tinkering around with some things & installed the former Debian-based factory OS & noticed that there's a CPU frequency widget that lets me set the CPU to 2GHz. I forgot this was a thing, so tried to set my CPU frequency (using the "cpupower" terminal utility) but the max I seem to be able to manage is 1.42GHz. I've tried a few different distros on a microSD but run Manjaro as my daily, so I'd like to know a couple things:

1) is it possible to set the CPU to 2GHz?
2) is it known why 1.42GHz is (or at least, is reported as) the maximum?

I thought maybe it was just an oddity with the Debian distro but it seems that 2GHz is reported in Pine64's documentation as the maximum frequency.

Any insight and/or suggestions would be appreciated!


  Ribbon cable routing
Posted by: monty1 - 10-26-2020, 05:29 PM - Forum: General Discussion on PineCube - No Replies

Got my camera, unboxed it, noticed one issue right away, the sensor(?) ribbon cable was not connected, which is easy enough to re-plug.  I'm guessing that manipulations of the wifi antenna (brown piece in the middle of first pic) made it come loose.  It's a rotate-to-close connector on the rear board, with the cable positioned in a way that any significant pressure would be towards the open position.  

Will give it a whirl tonight to see how things work.


  How to setup a ffmpeg streaming server on Manjaro?
Posted by: vfr400racer - 10-26-2020, 09:15 AM - Forum: Development Discussion on PineCube - Replies (4)

On my PinebookPro running Majaro, I try to setup a ffmpeg streaming server.

I start ffmpeg this way:

Code:
ffmpeg -listen 1 -i rtmp://localhost:1935/live/cube -c copy  rtmp://localhost:1935/live/mpv

As a result, ffmpeg is hangig as if it was listening on the socket. But when I check the sockets (e.g. with ss -a), port 1935 is not displayed.

When I try to stream from the pinecube, with this command: 
Code:
[root@nixos:/home/nixos]# ffmpeg -s 640x480 -r 15 -i /dev/video0 -vcodec flv -f flv rtmp://pbp:1935/live/cube
 I get this error:
Code:
[tcp @ 0x81110] Connection to tcp://pbp:1935 failed: Connection refused
[rtmp @ 0x80c10] Cannot open connection tcp://pbp:1935
rtmp://pbp:1935/live/cube: Connection refused
which can be expected, as there is nothing listening on port 1935 on pbp.

Has anybody got ffmpeg  working as a rtmp server or are you using nginx with rtmp support enabled?
Are there other lightweight streaming servers availabe?
Thanks for your help!


  Help to install vim (and others) in NixOS
Posted by: vfr400racer - 10-26-2020, 08:56 AM - Forum: Development Discussion on PineCube - No Replies

Hi All!

There is a NixOS image available for the pinecube. Coming across NixOS for the first time. I tried to install vim the way it is recommended e.g. here:
https://www.mpscholten.de/nixos/2016/04/...nixos.html

But when I try to switch to the new environment (hopefully this is what I am trying to do on NixOS Sad ), I get these

Code:
[root@nixos:/etc/nixos]# nixos-rebuild switch
warning: Nix search path entry '/nix/var/nix/profiles/per-user/root/channels/nixos' does not exist, ignoring

[root@nixos:/etc/nixos]#
Has anybody an idea how to fix this error?


  NixOS image availablee
Posted by: vfr400racer - 10-26-2020, 08:49 AM - Forum: Development Discussion on PineCube - Replies (5)

Hi All!

Daniel Fullmer has put a link to his github repository for the pinecube on the the pinecube wiki. I flashed the provided NixOS image to SD card and booted the pinecube. It took a bit to boot, but after a short while I was able to ssh to the pinecube. Following the instructions in his repository, I was able to record from the camera to a local file first try! Well done, Daniel!


  SimpNAS a possible alternative to openmediavault
Posted by: GreyLinux - 10-26-2020, 08:43 AM - Forum: General Discussion on ROCKPRO64 - No Replies

Hi all,

I've recently discovered a project that is an alternative to openmediavault , not that there is anything wrong with openmediavault , currently I run it myself.

However I believe in giving credit where credit is due and providing options is the strength of opensource software .

SimpNAS is a early development (beta) NAS solution (obviously Big Grin ) that is similar to openmediavault with a clean and simple interface, that might provide the solution for your NAS build .

I hope that by promoting an alternative it might help a few users who have been looking for options and also that it might encourage users who have coding skills a possible project to contribute to .

I am not associated with SimpNAS , I just find it an interesting NAS project that others might not yet have discovered .

  Need help with extra info to resize partition in EMMC
Posted by: pierrep56 - 10-26-2020, 06:04 AM - Forum: General Discussion on PinePhone - Replies (3)

Hello,
I am new here (and gald to be here). I have the postmarketOS edition, and I would like to flash the EMMC with the last Arch image. 
I have the Jump Drive on a SD card and I can boot from it. Also no problem to expose the EMMC drive in my Linux laptop.
Until there all good, but then I become confuse and wnat to be sure I won't make an error :
The wiki instructions says to run cfdisk to resize the partition., this is OK. But I am not sure WHICH partition to resize ?

I can see 2 partitions, the small boot one and a other bigger (Lucks encrypted)

[Moderator edit: Removed image that did not display properly]

Sorry if the question was already answered (could not find it) and sorry for what may be a noob question..... 
Do I need to resize (from the image above) sdg1 or sdg2 ? And to be 100% sure.... Must it be ext2 ? Can it be ext 4 ?
Thanks in advance for any help !


  zram
Posted by: guenther - 10-26-2020, 05:52 AM - Forum: PineTab Software - No Replies

I sometimes get some freezes in firefox under Mobian, so i decided to install zram with

Code:
sudo apt install zram-tools

than I changed the size of zram in /etc/default/zramswap to
Code:
PERCENTAGE=50

I expected the size of zram to be approx. 1GB, but
Code:
sudo swapon --show

shows only 1/4 of the size (252MB). I read it has something to do with the fact that the CPU has 4 cores!?
So what's the real size now? 252MB * 4, or just 252MB?

Please could someone of the more experienced users clarify that?

Edit: I found the answer at..tata...mobian wiki :-)
https://wiki.mobian-project.org/doku.php?id=tweaks

Anyway, because it seems the freezes have nothing to do with running out of RAM I decided to remove zram.


  PineTime is dead!!
Posted by: Markdanni123 - 10-26-2020, 02:25 AM - Forum: General Discussion on PineTime - Replies (12)

Updated my PineTime yesterday and it worked fine, update went through got the 0.8 validate tick thing and everything was fine, I placed it down for a second and when I went back to pick it up everything was dead, no screen turns on, no indication to say that it’s charging, just nothing what a waste of money this has been was actually rather excited to get my watch and see it develop into something awesome but nope!
