| How to add an external power button? |

Does the RockPro64 have header pins (or something similar) for an external power button? I would like to add such a button, since the on-board one can be difficult to use.
I see four holes at the corner of the board near the headphone jack. They're at the bottom right of this close-up view. One of those contacts is labeled PWR. Does that mean it's for delivering power, or will grounding it act like pressing the power switch? (The other contacts are labeled GND, REC, GND.)
If those holes are the contacts I need, what size header will fit them?
Is there a better way to do this?

I found it this script useful. So I'm sharing it.
It monitors CPU/GPU frequencies, temperatures and gives basic info from top.
Code: #!/bin/bash
a53=$(cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq | awk '{print $1 / 1000000}')
a72=$(cat /sys/devices/system/cpu/cpu4/cpufreq/scaling_cur_freq | awk '{print $1 / 1000000}')
cpu=$(cat /sys/class/thermal/thermal_zone0/temp)
gpuf=$(cat /sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/cur_freq | awk '{print $1 / 1000000}')
gpu=$(cat /sys/class/thermal/thermal_zone1/temp)
echo CPU temperature '>' ${cpu::2}C
echo GPU temperature '>' ${gpu::2}C
echo A53 Little frequency '>' ${a53}Ghz
echo A72 Big frequency '>' ${a72}Ghz
echo GPU frequency '>' ${gpuf}Mhz
echo ""
top 1 -bn1 | head -10
Copy code, save as eg. script.sh. Then:
If you want to refresh information every 0.5 seconds:
Code: watch -n 0.5 script.sh
Every 2 seconds:
Code: watch -n 2 script.sh

I installed manjaro 20.03 in march, and pretty much haven't touched the pinebook since april. Now I am back to it, every time I try to run pacman it can't connect to the package servers.
Is there any way of fixing this? Or will I have to completely reinstall to a newer manjaro? I just want to install a few more packages and update what I have.
I get this output:
Code: :: Synchronising package databases...
error: failed retrieving file 'core.db' from manjaroarm.mirrors.lavatech.top : Could not resolve host: manjaroarm.mirrors.lavatech.top
core is up to date
error: failed retrieving file 'extra.db' from manjaroarm.mirrors.lavatech.top : Could not resolve host: manjaroarm.mirrors.lavatech.top
extra is up to date
error: failed retrieving file 'community.db' from manjaroarm.mirrors.lavatech.top : Could not resolve host: manjaroarm.mirrors.lavatech.top
community is up to date

there is nothing to do

| Questions about the PinePhone component list |

I have compiled a list of the components in the PinePhone v1.2a by looking at the schematic:
https://wiki.pine64.org/index.php?title=...onent_list
However, I have several questions, and maybe someone here can answer them.
What do the abbreviations DU, ED and FB mean when they are used to identify components? - DU : "U" is for an integrated circuit, but not sure what the "D" means. (e.g. DU1)
- ED : "D" is for a diode, but not sure what "E" means. (e.g. ED600)
- FB : ? (e.g. FB804, FB805)
Also, I see 2 accelerometers/gyroscopes on page 12 of the schematic:- U1202: TDK InvenSense MPU6050 six-axis, low-power MEMS gyroscope and accelerometer, QFN-24 4x4x0.9 mm [datasheet]
- U1204: Bosch Sensortek BMI120 3-axis gyroscope and accelerometer, LGA-14 2.5x3.0x0.83 mm
Note: Listed as “NC/BMI120”, where “NC” probably means “not connected”, so there may be circuits in the PCB for the part, but it is not placed on the board. This is probably an alternative to the MPU6050.
It looks like the Bosch part is not placed on the board, however, it looks like there are two magnetometers in the Pinephone and I can't figure out why:- U1200: STmicroelectronics LIS3MDL ultra-low-power three-axis magnetometer, LGA-12 2.0x2.0x1.0 mm [datasheet]
- U1203: Asahi Kasei Microdevices (AKM) AK09911 3-axis electronic compass IC with Hall sensor, 8-pin WL-CSP (BGA), 1.2×1.2×0.5 mm
or
- U1203: Voltafield Technology Corp. (VTC) AF8133J 3-axis electronic compass with proprietary anisotropic magneto resistive (AMR) technology, 8-pin WLCSP 1.2x1.2x0.5 mm
Note: Both parts are listed, so have to check the PCB to see which was used. It is not clear why this part is needed when the device already has the LIS3MDL.
Can someone please check on their PinePhone whether there are really two magnetometers and which models are being used.
Another question is whether the schematic for the Pine64 doesn't include all the circuits. I noticed that the schematic for the Librem 5 has twice as many parts as the PinePhone and has a lot more detail. I have compiled a list of the parts in the Librem 5 and the difference is noticeable:
https://source.puri.sm/Librem5/community...onent-list
Is the schematic for the PinePhone complete or did Pine64 leave out some of the circuits?

I just ordered a PinePhone, and I've been doing some reading on the wiki... It sounds like it will be possible to get several SD cards, and install a different OS on each card, and then swap OSes by powering off, swapping the SD card, powering back on. Is that correct? I'm hoping it is, because it will make it super-easy to try out some of the more interesting (and maybe less polished) OS options.
Is there any particular reason to install an OS on the internal storage (versus SD card)? Maybe better performance?
