| SystemImageKit? |

I was just browsing through some AppImage stuff and stumbled across this:
https://github.com/probonopd/SystemImageKit
It made me wonder if this isn't ideal for SBCs, phones, etc.
What if /boot/grub2 (uboot in our case?) existed on some small bit of NAND,
along with /boot/SystemExtensions (chip/board-specific binaries not yet in mainline kernel, lima, panfrost, etc)
while /boot/iso is a symlink to the SD card with live ISO images with mainline kernels,
and persistent $HOME/ resides on either SD card or installed eMMC.
Is this a viable future path for SBCs and devices like PinePhone/Tab?

| How to switch to OTG from usb-network? |

I am playing with pinephone and somehow its stuck with usb0 as network device attached to usb connector. I want to use mouse and keyboard and be able to switch between those two modes.
How do I do that?
PS. I think i had the OTG cable working once but now both my distros (MATE and XFCE) are stuck with usb-net.

Hi Everyone,
How's your wifi performance? I'm interested in figuring out what the maximum is, and what kind of access point is going to work best with the pinebook pro.
Please post iperf measurements, ideally within LAN, and details of your wifi setup.
I'm getting 20.5 Mbits/sec to a wired machine on my LAN, using the 5Ghz band and a NETGEAR C3700-100 router. I'm sure you can do better than that!

Getting Started: Maemo Leste - Devuan / Debian distro for your PinePhone |

Did you know Maemo Leste is Debian for your PinePhone? For real! It is Devuan with the arm64 architecture running on stretch. They will soon be upgrading to buster and supporting both Debian and Devuan simultaneously. They use automation in their package maintenance with jenkins (similar to debian's buildd) to ease porting and updates. Porting packages to Maemo Leste is basically a simple matter of porting to arm64 version of Debian, which benefits both projects. So you will pretty much have all the benefits of the Debian repository, especially as the project matures. In addition to the main repositories, there is a community repository (so, like AUR).
There have been a few parallel attempts to port Debian to the ARM architecture, Maemo being the longest running. Currently, the project for porting Debian to arm and arm64 is unmaintained. You might be wondering, why hasn't this been done sooner? Simply put, everyone has been relying on the Android kernel, so benefits are not making it back to Linux. However, there are a few more projects for Debian on ARM (mainly ARM64) including PureOS, Dragonbox Pyra, Armbian, and Debian + phosh, so that's about to change rapidly.
Most discussion about Maemo occurs on their website and platforms, go here for an updated list of links. There is an ongoing thread about Maemo Leste for the Pinephone.
With volunteers we can easily test and get it to a stable condition on the PinePhone, so I compiled some useful links:

| Battery life and ways to improve - request for official statement |

Hello folks,
so far I didn't see any official statement why the battery life is so poor and whether there's anything to try/test to improve it. This should be the top priority imho! Observations:
- it's always top of the phone which gets hot (where the modem is located).
- touching the uncovered modem my guess would be between 55-65C all the time. This higher heat from the modem can be felt also on the screen side
- pmOS with plasma-mobile is way cooler based on my tests today than the Phosh image (tested today with latest images, no SIM)
- checking the CPU frequencies seems to be ok, however the lowest frequency seems to be high imho, is this due to hw limitations ? Trying to set the available frequencies to be lower didn't do the trick
Code: current CPU frequency is 648 MHz (asserted by call to hardware).
cpufreq stats: 648 MHz:73.58%, 816 MHz:3.03%, 912 MHz:0.67%, 960 MHz:0.54%, 1.01 GHz:0.60%, 1.06 GHz:0.57%, 1.10 GHz:0.84%, 1.15 GHz:20.17% (4271)
- is there any way to exactly track what is eating up the battery ?
- is the a known method to reduce power usage siginificantly ?
- is there any supported way to measure the temperature of various components in alpine linux ?
- why is the modem so hot even though I have no SIM inside the phone ?
Cheers!
