  Hardware killswitch alternative
Posted by: deckaddict - 04-22-2020, 01:33 PM - Forum: PinePhone Hardware - Replies (4)

I've seen several threads that has mentioned that the kill switches are a bit hard to reach and awkward to use in a smooth way. At the same time I understand that it is an added complexity in the manufacturing process to make them external.

My suggestion.

As a user I can in principle not verify that the kill switches work but have to trust the hardware manufacturer. So I wonder if it would be possible to instead have a LED solution that can show if the HW is disabled, these LED's can be assembled in a way that software can not turn them on/off without also impact the power mgmt to these components.

The good things with this is that it can make it possible to use software switches instead which can be very easy and convenient.

The drawback is of course that there would be need for extra hardware drivers specifically for this device, but maybe it can be worked into some sort of standard.

There are many details to figure out here. For example it is important that the software can not control when the LEDs are turned on at all, so either they are constantly lit or there is one external test button that can be used to check the state to ensure that the software can not turn on/off only before showing the LED state.

Just wanted to share the idea.


  SOPINE Network boot
Posted by: Ninazu - 04-22-2020, 01:09 PM - Forum: Linux on PINE A64-LTS / SOPINE - Replies (1)

I have a Clusterboard and 7 Sopine modules. And one SD card with a configured system. Does SOPINE support network booting? So how is this possible in RaspberryPi?

  How about a arm based pine 64 mini to go with the pinebook
Posted by: Omnios - 04-22-2020, 11:39 AM - Forum: General - Replies (8)

I find it is interesting that there is a pinebook 64 to purchase but am thinking that it would be nice to have a higher end arm based Pine Mini based loosely as something similar to a mac mini or a Nuc computer as a project mini desktop. The general idea would be a usable mini arm computer of many usages suck as a Media box, large screen tv web surfer, software development device and other options such as a media center. So not quite a pc desktop but way more advanced than a arm media center and usable as a computer for say Arch Linux for pine arm development with a high end arm system with a newer arm processor as they are getting to the point to be competitive with a X86 system.

  opemmediavault plugin error on "Check"
Posted by: clach04 - 04-21-2020, 10:13 PM - Forum: Linux on Rock64 - No Replies

I've been experimenting with pre-release and stable builds of Open Media Vault for rock64 (see https://github.com/ayufan-rock64/linux-build/issues/426 but right now I can only get stable to boot).

Occasionally when hitting "Check" for plugins I get and error popup with:


Code:
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; apt-get update 2>&1' with exit code '100': Reading package lists...

I think it is failing due to missing sudo, running in ssh session as root works:


Code:
root@rock64:~# export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; apt-get update 2>&1


  Blood pressure estimation from heart rate sensor
Posted by: wibble - 04-21-2020, 08:36 PM - Forum: General Discussion on PineTime - Replies (8)

https://www.nature.com/articles/s41746-019-0136-7#Sec9

I wondered how the original firmware was supposed to get blood pressure from the available sensors. Perhaps it was using one of the methods outlined in the link. Samsung's latest watch is claiming to measure blood pressure too, but needs calibration from a normal cuff at least every 4 weeks to maintain accuracy.


  Wifi drops out frequently (dev phone)
Posted by: jfloren - 04-21-2020, 07:19 PM - Forum: PinePhone Hardware - Replies (2)

I've got a dev phone (pre-Braveheart) running Debian+phosh with the ssh server running. I find that my connection frequently hangs and stops responding, only to "catch up" a minute or two later, but in general ssh is almost unusable. Continually pinging the phone from my laptop seems to help keep things alive a bit, but I'll notice that it sometimes takes up to 15 seconds for the ping response to come back. I'm sitting about 15 feet from the wifi AP.

I recall some discussion about problems with the wifi antennas on dev phones; is this what's biting me, or is there some kernel parameter I need to tweak or something?


  No underscores visible/typeable in the Geany IDE.
Posted by: Faradn - 04-21-2020, 12:08 PM - Forum: General Discussion on ROCKPRO64 - No Replies

SBC:    RockPro64 4Gb v2.1
OS:     Manjaro-ARM 20.04
           Linux rockpro64 5.6.0-1-MANJARO-ARM #1 SMP Tue Mar 31 12:35:20 CEST 2020 aarch64 GNU/Linux
        
I'm using the latest version of the Geany IDE to work on some GPIO
projects and one cannt see *ANY* underscores ``_'' in the source
files.

Oh and Pamac is starting to mis-behave; locking up and freezing
the desktop environment.

Any ideas/suggestions?

TIA,
/Faradn

  br_netfilter
Posted by: LMM - 04-21-2020, 09:11 AM - Forum: Linux on RockPro64 - Replies (4)

Hi all,
I flashed the 0.10.12 linux image with container capability. But I am facing a problem : the file /proc/sys/net/bridge/brige-nf-call-iptables is missing and I cannot initialize Kubernetes (kubeadm init) : an error rises.
modprob br_netfilter returns an error because the module is not found

I will try with the stable version.
