  eMMC not gets detected by initramfs?
Posted by: overlisted - 10-27-2020, 03:47 AM - Forum: General Discussion on Pinebook Pro - Replies (6)

Hi, this is my first thread, I'm new to PINE64 and need help with a Pinebook Pro.

So... My PBP has elementary OS installed on its internal disk, but after not charging for a while (I guess, it can be some other cause), initramfs stops detecting the eMMC... It says something like "UUID=xxx not found dropping to shell", and in the busybox terminal I found out that there's just no mmcblk2 detected! In /sys/block/ there's only mmcblk1 - my SD card! But the eMMC is definitely not dead, because the PBP still can find the bootloader from eMMC.

So what happens inside my PBP so initramfs can't detect it, but the firmware does??? And the problem just dissappears when charging for a while again?


And sorry if this question is stupid and it's on the first page of some documentation and was answered ~90 times on this forum and it would get 1000 downvotes on stackoverflow.


  Is there any risk in plugging the PinePhone into a powered Thunderbolt dock?
Posted by: Mark53 - 10-26-2020, 10:33 PM - Forum: General Discussion on PinePhone - Replies (2)

I have a Dell TB16 dock at work and thought of a use case for it with my Pinephone, but since the Thunderbolt connection is normally used for powering a laptop and replacing a 130W, 19.5V power supply, I'm hesitant to plug it into my phone. This means the phone would have to negotiate the dock down to a supported voltage (if the dock hardware allows it) or reject charging at all.

Is there any realistic chance that this would damage the phone, or should it be fine?

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

[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 .
