I've been troubleshooting two Pine64 2G LTS boards for several days now and I haven't been able to get either to boot. I've read the instructions on flashing an SD card and the troubleshooting section in the Getting Started section of the wiki. I've also read the relevant threads in the aptly named Useful Threads posts, yet I haven't gotten a board to boot yet.

I've used balenaEtcher to flash two, known good, SD cards with Armbian 22.11 Jammy XFCE. I also tried the CLI version on both SD cards for thoroughness sake. Still no dice. I flashed the devices on a Windows 10 machine and on a Ubuntu 22.04 machine with the same result. The same SD cards can successfully boot other SBCs I have. I've powered both boards with a known good bench top power supply via GPIO pins 1 and 3 and with a 5V 2A power adapter. I can't actually confirm that the power adapter is good because the LTS boards are the only devices I have that accept the barrel connector. But regardless of how I power the boards, a green power LED lights up. My bench top power supply says the LTS boards are pulling ~125mA if that helps troubleshoot. The same supply can power much hungrier dev boards I have.

I've used two, known good, HDMI monitors with two, known good, HDMI cables to see if screen resolution was the problem, but that still didn't work. I connected a known good Ethernet cable to both LTS boards and there is no activity on the pine 64 nor the port on the router. The same port and same cable plugged into other devices supplies Ethernet and lights up the jacks on both ends. I left a board on for a while and checked devices connected to my router just to see if it had an IP address, but no dice.

I even tried randomly pressing the power and reset buttons to see if that changed anything, but I'm seeing no signs of life from either of the boards I have. Since I can't even SSH into either device I've basically exhausted all the trouble shooting options I can think of. All the tools I'm using are working with other devices on my bench.

I tried flashing an SD card with Manjaro to see if it was an Armbian problem but couldn't get the installer to run on my Ubuntu machine. I intentionally buy two devices when bringing up new-to-me devices to rule out a DOA board. The fact that I have two boards that refuse to boot makes me think I'm doing something wrong. This isn't my first rodeo with open source hardware, but I'm out of ideas. Any troubleshooting suggestions will be greatly appreciated.

Hello,

Is there a way to export accelerometer and ppg signals to a computer? 

Thanks

Hi, recently ordered pinebook pro. For the first couple days it worked just fine, and then one day the display just completely stopped working. As far as the green LED is concerned, it powers on and off just fine whether plugged in or on battery.

Sorry I'm new to this, but here's what I've done so far (spoiler alert none of it has worked):

1. Took the base off, and hit the reset button (and I made sure the emmc module switch was on).
2. Demonstrated my Galaxy brain intellect by taking the base off again, disabling the emcc switch, spent 5 hours backing up several years of important stuff stored on my SD card, flashed Armbian to the SD card, and then realized the PBP doesn't actually have a full sized SD slot. Turned emmc switch back on.
3. Downloaded Manjaro, wrote it to a USB drive using https://gitlab.com/bztsrc/usbimager and tried to boot that way.
4. Connected a USB-C cable to a USB-C monitor.

I'm still a bit lost on all the USB versions so I'm not 100% sure if the USB-C cable I grabbed supports DP alt mode, but I'll double check that when I get off work here in a few minutes. If that doesn't work, my next idea is to redownload Manjaro, flash it to a USB drive with Etcher, disable the EMCC switch and attempt to boot that way. aaaand if that doesn't work my next thought would be to take advantage of the 10000 mAh battery and thin metal container and use it as a desktop hotplate/coffee warmer. That's not exactly what I had in mind when I ordered it though, soooo any suggestions would be greatly appreciate. 

Hi everyone!

Today I reinstalled my PB Pro with last Manjaro distro. When a started process of installation of all my soft at previous instance I faced a problem with transaction commit. After any soft installation attempt I have error "nvalid or corrupted package (PGP signature)" (even pacman in terminal). I found some advises about refreshing keys, but still haven't solution. Please help to solve it.

Installation example:

Has anybody successfully remapped keys in the physical kb? I've tried xmodmap and xbindkeys, and while I'm not producing errors in console, I'm not producing the changes either.

My goals:

/? = Right Shift
AltG+3 = Slash
AltG+4 = ?

Any advice about how to pull this off?

EDIT: specs = PinePhone + Manjaro Phosh Beta 29

I've noticed for a while now that after booting up my Pinephone and connecting wifi that internet access wasn't working. It turns out that a default gateway of 192.168.225.1 on device "enxxxxxxxxxxxxx" is spontaneously appearing:

Dear all,
could anyone please advise about the best way to receive information about the PineTab 2?
I visit their page every now and then, but I never see any news.
I was hoping I could buy one after the Chinese new year, but it seems it's too early
Which is the best way to be informed? This forum, the discord chat, or the matrix group?
Thank you in advance if you can help me

for a preview, this shell looks very ok. Nextcloud syncing (for Calendar and Contacts) is a breeze, where in KDE it never worked properly. Nextcloud desktop is not that easy, it does not seem to work. Gnome mobile crashes on install. But it looks like a well designed and actively evolving system. Diealer, Contacts, Calendar are more touch friendly as KDE's and also the to-do list connects to NextCloud. However I'd wish a screen resolution between 100% and 200%, first is too small and 2nd too big for me. Also the search field takes much space and does not go away when not needed.

According to the pine64 instruction, pine phone should only be connected to its special keyboard, customers should not use generic USB keyboards to connect to the pinephone because it would cause the USB keyboard to charge the phone, that does not make sense, I have a DELL laptop that can only be charged by a USB power supply, I can connect to the USB keyboard or any USB peripherals to the same laptop USB socket whout charging the laptop battery

I would like to see pine phone is more flexible in regard to USB peripheral connections, I thought it should not be hard in hardware design to only allow the USB power supply unit to charge the battery and to filter out other peripherals for battery charge, are there any reason why the pine phone could not do it?

Thank you.

Kind regards,

Hello,




I am considering to buy a pine64 phone, will I be able to run ssh from my laptop to connect the pine64 when both connect to my home WiFi?



Thank you.



Kind regards,
