  Pinebook Pro as an all-in-one boat server?
Posted by: nhm - 05-15-2020, 01:14 PM - Forum: General Discussion on Pinebook Pro - Replies (8)

Hi Folks,

I would like to make an  all-in-one plex media server and wireless router for a boat.  Here's what I'm looking at as high priority items:

1) low power usage, run off 12v batteries
2) low physical space usage
3) no HDDs (waves, power!)
4) Host local wifi network for boat
5) preferred list of remote access points to route through (Home marina, other marinas, phone hotspot, etc)

I was first considering simply using a RockPro64, but it looks like I would need to make a custom case for it or use the NAS case which is larger than I'd like.    I'm considering instead using a pinebook pro, leaving the lid closed, and mounting it inside a closet.  A couple of bonus advantages: 

1) Battery backup
2) integrated screen/keyboard if network goes down
3) Functional as kids laptop if project doesn't work out.

Downsides:

1) m.2 tops out at 2TB while SATA and U.2 offer larger sizes (and can be cheaper/GB)
2) Don't strictly need the keyboard/trackpad/screen (but nice to have).
3) Heat a concern inside a small closet?

Any thoughts on whether or not this would be a good plan?  Any concerns with power/heat or ability to host a second wifi network (USB3 dongle?

Thanks!


  Boot sequence
Posted by: Zweitaktmotor - 05-15-2020, 11:49 AM - Forum: PinePhone Software - Replies (5)

Hi,

Is there any way to bypass the boot sequence of the Pinephone?

The two leading software contenders now seem to be Ubuntu Touch and Mobian. Both can be updated on a rolling basis.

I have Ubuntu in the phone and Mobian on a card and would like to keep an eye on both. - But I cannot do so without juggling the SD card in and out.

I have no idea about programming, but can't we have a solution like the Grub menu on the desktop? That would make things so much easier!

[Dreaming mode on] Ideally, I would like to see an OS with the slick look of Ubuntu and the functionality of Mobian, but I guess this is unlikely to happen, at least not any time soon.[Dream mode off]

External display

Please chime in with other features and the state of the list above
Thanks


  How to enable SSH on UBPorts Ubuntu Touch?
Posted by: eaglecup - 05-15-2020, 06:30 AM - Forum: UBPorts on PinePhone - Replies (12)

This might seem like a beginners question - which it is. How do I get acces to the pinephone from my laptop?

With the Ubuntu-Phosh image I managed to get this to work easily, just like on a Raspberry Pi. But it's lacking the camera drivers I'm trying to acces (I'd like to work with the camera in python)
With the latest PostmarketOS image I don't even see how I can open a shell on the phone itself.
With Ubuntu Touch I can access a shell, but the normal `apt-get install openssh-server`doesn't do it.

I read somewhere that there is a change in how the new UBPorts images handle SSH in the first place, in order to improve security. But I can't find how to enable it anywhere.


  Looking for Small Board
Posted by: stefan.schumacher - 05-15-2020, 02:49 AM - Forum: Pinebook Pro Hardware and Accessories - Replies (2)

Hello,

two months ago I accidentally damaged the MicroSD Port of the Small Board of my Pinebook Pro while trying to get out a MicroSD card with a pair of tweezers. Now I want to install Manjaro and need a replacement small board. It's not available in the parts shop. Is there someone - idealy in Germany - who has a spare small board and would be willing to sell it to me?

Yours sincerely
Stefan


Bug How about a hard power switch? + crash report
Posted by: Dendrocalamus64 - 05-14-2020, 11:12 PM - Forum: General Discussion on Pinebook Pro - Replies (7)

Debian + MATE MrFixit version 2.0
Kernel: Linux Debian-Desktop 4.4.213 #1 SMP Fri Feb 7 13:03:55 EST 2020 aarch64 GNU/Linux

While playing an mp3 with mplayer through the internal speakers, I had the system freeze so hard that I had to take the back cover off & push the reset switch to get it to reboot.
For the next incremental hardware tweak, how about adding a hard power switch in a more accessible location?

The last thing it wrote to the logs:

IIRC it was actually still running after that. The next time I tried to play the mp3, it froze. There was soft static coming from the speakers.


And then when I tried to post this, the PBP rebooted. That didn't leave any message in the logs [edit] but there's a console-ramoops-0 and dmesg-ramoops-0 in /sys/fs/pstore that look like they're from the right time.

  Configure Mynewt for SPI Flash
Posted by: lupyuen - 05-14-2020, 06:18 PM - Forum: Development Discussion on PineTime - Replies (3)

Hi All: Here's my new article that explains how we may access PineTime's SPI Flash with Mynewt OS. 

We'll be using SPI Flash in the MCUBoot Bootloader for storing the old firmware, so that MCUBoot can roll back to the old firmware if the new firmware doesn't start.

Configure Mynewt for SPI Flash on PineTime Smart Watch (nRF52)


  RockPro64 Slow Ping on WiFi
Posted by: jl_678 - 05-14-2020, 05:08 PM - Forum: Linux on RockPro64 - No Replies

Hi,

I have a RPro64 with both WiFi and wired Internet. (WiFi via the Pine64 add-on.)  However, I have a weird network performance issue.  When the system is online via Ethernet, it responds instantly via SSH on my local LAN as one would expect. (Ping times are <1 MS on my local LAN.)

However, once I unplug the Ethernet cable either while online or after a reboot, ping times collapse and range from 5 milliseconds to over 4000 milliseconds.  This also affects SSH which becomes very unresponsive. (e.g. I type a key and the letter does not appear for a bit.)  The RPro64 is online and reachable, but very very slow.

I am trying to decide what is going and welcome any feedback.  In case it matters, I am running Ayufun's 0.9.14 stable Ubuntu minimal release.

TIA.


  restart trackpad without reboot?
Posted by: gleachkr - 05-14-2020, 02:22 PM - Forum: Linux on Pinebook Pro - Replies (4)

My trackpad mostly works pretty well, but occasionally gets into a weird state---the cursor moves randomly when I lift my finger off the pad, and taps are registered at random (even with no hands on the computer) or (more recently) no taps are registered at all. No useful information from journalctl or dmesg.

But: a reboot resolves the issue.

So I'm wondering if there's some way to powercycle the trackpad, or to reload the drivers, or anything that might help with the issue above, without a complete reboot.

Ideas?

This is on Manjaro, release 20.05


  [BH] Issues booting from eMMC with NON-BOOTABLE SD card inserted
Posted by: Segfault - 05-14-2020, 11:51 AM - Forum: PinePhone Hardware - Replies (7)

Hey all,
    I've scanned the forums and haven't seen this mentioned before, but apologies in advance if it has.
    I've flashed a distro to my eMMC flash and it's working great with one exception. Cold booting with a non-bootable (no OS installed) flash drive doesn't seem to work.
     In the past, booting from an SD card, I would insert the SD card, re-insert the battery and press+hold the power button for several seconds and I see the usual boot sequence starting; within a few seconds the status LED would cycle through it's colors and then I'd see a brief flash from the bootloader on commandline before my OS of choice's boot logo, etc...
     Now that I've installed to eMMC, when I power up with a non-bootable SD card inserted, none of the above occurs, not even the status LED cycle, which leads me to believe this is a hardware/firmware issue more than OS/software.
     From what I've read in the wiki, the firmware is set to scan the SD card before attempting to boot from onboard memory.  I've checked the drives I'm using and they are not flagged as bootable in gparted, so I'm wondering if the firmware isn't checking for a boot flag, but just the mere presence of an SD card?

     This isn't a terribly urgent issue for me, but I was wondering if others have experienced this as well. Perhaps it's only on the Braveheart edition? If so, does anyone know when PCB 1.2 will be available in the Pinephone store?
     Thanks in advance!
