I think that the best retro emulation system is Android with Retroarch, because it runs without the problem, so I installed Android 9 with play store. Everything works except Kodi, it keeps crashing every time I run it. Can anyone confirm that it is not a problem with my RockPro? Maybe I should try older Android?

Hello, Would someone know GPIO pinout for these header on Popcorn Hour Transformer.
Thanks.

Hi

As the system is changing constantly at the moment and I often update the image I am looking for a way to backup user data and settings
and restore them once the new image has booted or even before writing the image to the SD card.

E.g. how to backup and restore:

• WiFi set up via the Posh UI
  
• call logs
  

Hello everybody,
I have an application written in electron for raspberry. Without going too deep, it's just set on/off some GPIO output at some predeterministic time.
I just bought a PINE A64-LTS, installed last armbian verson and ported the application, which start just fine.
My problem is now the gpio configuration, with raaspberry I use pigpio package (https://github.com/fivdi/pigpio), I was wondering if there is a similar library to use/manage gpio in electron framework.

thanks a lot for any good advice





hehehelloasas

does anyone know why certain packages aren't compiled for aarch64 but are for eg. armv7? I want to install rofi, but it's only available on armv7. there's no place to comment or feature request on the alpine packages site, the only option is to flag out of date, which the packages aren't.

In the "settings -> default applications" menu, I can't choose "firefox" in the "web" dropdown (in fact, I can't choose anything), and so links from other applications open with the text editor. similarly, "text editor" is selected as "calendar", and it's the only option, despite having Calendar installed.

Is this a known issue? If not, where should I report it? And lastly: can these settings be changed from the command line?

I tried the "usual" tricks like volume up + volume down, volume up + power to take a screenshot on my PinePhone with Manjaro + Phosh, but it doesn't work. I read on this old blog post that it's now possible, but it doesn't explain the procedure. How can I do it?

Hi,

Apologies if this is a stupid question, or if it's already been answered before...
I've got an OS installed on my SD card and the SD card is inside the Pinephone. So, when starting the phone, I have no choice but to boot from SD?
Is there any way I can then flash the SD card with a different OS from the Pinephone itself?

Thanks

Well, I already managed to drop my Pinephone about 2 feet onto a plastic chair mat and the lower left part of the screen cracked. (The soft case either didn't protect it or prevented worse damage, hard to say which.) It actually is not that bad as the crack is mostly in the blacked out part of the bottom, but it will probably spread and seeing as how replacement LCD panels are available for only $30 I figure it should be replaced. I searched for a guide but didn't find one. How tough a job is this? (I'm pretty comfortable taking various types of equipment apart and putting them back together.)

Edit: After kicking myself for dropping the thing I've taken a closer look. Fortunately although one leg of the crack spread across the screen diagonally it does not affect the image or touch. Really if you were not looking for the crack you'd barely notice it. Still, I was about to buy some accessories anyway so I added a replacement screen to my cart and ordered it. I've checked that I have a precision screwdriver small enough for the tiny screws and am set there.

Would love to hear from anyone who has replaced their screen as to the procedure. Searching all I've found are some references saying it's not difficult. I see there are 11 screws around the perimeter of the case, I assume those all have to come out. There are also 3 screws down the center, do those get removed also? What do I need to look out for when taking this all apart?

I have an Inland Cellular SIM card. Inland is NOT an MVNO and Inland owns the only towers and provides the only cellular service in my part of rural Idaho, US. I really wanted PinePhone to work and I'm very disappointed. (I will give up mobile phones entirely rather than use a spy phone, even though the telecom networks still spy on those of us using PinePhones.)

I hope someone here has a few ideas or suggestions that will help me.

My PinePhone receives an Inland 4G signal and Internet data works, but voice and SMS text are completely non-functional (inbound and outbound). The Inland tech was very helpful and even loaned a Samsung phone to me that, of course, works reliably on their network. I use the loaner phone to check SIM settings, signal strength, and functionality. (I appreciate the "hometown" feel and personal support of this carrier, compared to my previous dealings with Verizon, AT&T and a couple of their MVNOs. The tech was very interested in my PinePhone too!

I also tried my old, no longer subscribed Verizon SIM card some miles away where Verizon towers are visible. It too produced a good 4G signal bar indication, but I have no idea whether or not Verizon would work because the subscription has expired. Guess I could have tried calling 911!

The Inland tech told me that Inland does not support VoLTE but they are working on it. The following Inland frequency and band specs are posted at https://www.signalbooster.com/pages/what-are-the-cellular-frequencies-of-cell-phone-carriers-in-usa-canada.

Inland Cellular

3G Frequencies / Wavelengths
3G : 835 - 845 MHz, Block B Band 2 (CDMA2000). 880 - 890 MHz, Block B Band 2 (CDMA2000).

4G, LTE, 5G frequencies / Wavelengths
4G : 800 MHz ESMR, Band 26 (LTE700). 1900 MHz PCS, Band 25 (LTE700). 2.5 GHz BRS/ EBS, Band 41 (TD-LTE700/ LTE Advanced).


The following PinePhone specs are summarized in the wiki: https://wiki.pine64.org/wiki/PinePhone#Specifications

Communication: G25-G

LTE: B1, B2, B3, B4, B5, B7, B8, B12, B13, B18, B19, B20, B25, B26, B28, B38, B39, B40, B41 WCDMA: B1, B2, B4, B5, B6, B8, B19 GSM: 850, 900, 1800, 1900 (MHz)

Though I'm a retired electrical and computer engineer, I find cellular freq / band and modulation specs to be baffling. Are these Inland and PinePhone specs compatible? What is the difference between CDMA and WCDMA?

I tried Manjaro Phosh (I updated to Beta2 level using pacman) and I also tried UBports Ubuntu Touch (Lomiri) and Mobian (Phosh) from the p-boot build and multi bootloader. Actually, I tried all the OS images on the p-boot SD but only Ubuntu and Mobian worked to check or set the APN and establish a connection. They worked far better than Manjora Beta2, in fact.

Manjaro Beta2, updated from OEM and booted from eMMC, was barely usable to set the APN and connect to the Inland network, because the Manjaro Beta2 cellular settings are unstable. I never figured out how I sometimes managed to get a connection (accompanied by Internet data) and Manjaro always required a lot of setting, resetting, and turning the modem off and on. Sadly, the effort was always lost at each reboot.

But these OS configuration utility issue are subjects for other bug reports and p-boot Mobian and Ubuntu seem reliable enough to test any suggestions forum members might prescribe!

My next step will probably be to download the factory test image and boot it from an SD card. Factory-loaded Manjaro build with testing utility. Maybe the test utilities will detect something wrong with my hardware.

Although I was mostly a hardware and signal integrity engineer before I retired, I did a lot of low level programming (boot ROMS, device drivers, diagnostics) during my career and a good deal of it was for *NIX operating systems. I'd very much like to solve this partial, but critical, Inland non-functionality (Internet data IS working). Hopefully I'll then find the spare time to contribute to this project as a developer. (I'm actually busier than ever in retirement on this old rural Idaho homestead!)

Thanks so much for reading and thanks for any help that you may be able to provide to me!
