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
:: Starting full system upgrade...
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?

| Arch Linux Arm - external RTC problem |

I have connected an external RTC module (ds3231) to a Rock 64/4g.
I've loaded i2c-dev modules and rtc-ds1307 modules but my rtc mod is not detected by i2c (i2cdetect shows nothing connected at address 68)
Hardware is ok (if I boot with ayurfan distro I can see the external RTC module).
Could it be a kernel configuration problem? Has anyone had similar experience?
My Linux distro is Arch Linux Arm.
Regards
Max

| UBports: headsup for Manjaro! |

I like many others have remained focused on ub ports since the bulk of PP users either seem to use it or postmarket. I love the UI and responsiveness, consistent operating temp and overall stability. We appear to be very close to a working daily driver yet many things seem incomplete, held up in dev for a long time and it is taking a long time to iron out many bugs. Aside from UBports, i thought mobian may be showing the most promise and fastest progress. Until today, i checked into the very quiet Manjaro forum which has had limited activity and voila! Guess what? Looks like they have almost everything working and stable. Im posting this here under UB ports for one reason: i really like ubports and i think its got amazing potential. I think the devs here should take a good hard look at what Manjaro has quickly and simply done with a smooth and rapid roll-out. I feel some lessons can be learned and we can get ubports up to par! Perhaps ub & pmos got a bit too big and complex too fast making it harder to troubleshoot while manjaro kept it simple?
