Greetings!

I am interested in getting a Linux-based tablet for grading. I unfortunately have to use BlackBoard Ultra for grading, or else download student papers (PDF or Word format usually). I don't plan to use the tablet for anything else except reading journal articles and/or books.

Would the PineTab or PineNote be better for this particular use (primarily grading)? My sense is the stylus would be great for making grading faster (as opposed to typing comments, which requires highlighting particular passages using BlackBoard's clunky in-browser system and typing, which I think is slower than my writing), and the PineTab (I think?) isn't compatible with a stylus.

Advice on one or the other would be greatly appreciated. Thank you kindly!

Hi everyone,

Using PineWatch and reading Open BLE was very easy to implement to my App.
Just with Built in OS.
So far, im using HeartRate in my App, no Gatebridge needed, just simple as can be. 

Thanks for that.

Hi,

I am interested in knowing if anyone has been able to run Instagram or discord apps using waydroid (or alternative setups) on the pinephone with stable performance. I am also interested in knowing if anyone has been able to run any youtube app with stable performance. 

Aside from the proprietary apps, I would also love to hear from anyone using alternative opensource apps? I know some projects exist for discord, such as WebCord, ArmCord and maybe there are more projects like those some of you have had success with and would like to share.

Please also share what OS + mobile shell combination you are using and anything else you can think of that was important for performance and stability.

cheers!

Hi,

I re-registered my nick yesterday on IRC because I have been inactive for a while. I have not received a confirmation email and I just wanted to let you know incase my registeration got missed somehow. My IRC nick is dustfinger, just like my forum username.

Thanks,

dustfinger.

Would cpu rk3576 be suited for running a phone? My information is that the cpu rk3576 is able to run
on free software except from a ram training blob. Thank you.

I noticed mesa updated on my pinetab2, so i tried it out.

both mpv and browsers got a HUGE speed boost, with almost perfect video playback.

I would further recommend

Debian 13 / xfce with Daniel Thompon's ancient 5.7 kernel and updated touchpad firmware (too long ago that I remember the details).

Under xfce -> settings -> mouse and touchpad, I checkmarked "tap touchpad to click". Tap to click works with one finger taps, only. For 2 or 3 finger clicks, I need to press the touchpad.

On other computers running Debian / xfce, I can tap with two and three fingers as well.

What about you? Does it work for you on the Pinebook Pro and I just need to dig deeper?

Hello,
I just flashed postmarketOS onto my PinePhone Pro, and everything seems to be functioning well, except the OS can't detect the battery. There's no battery indicator in the top-right corner of the screen, and the settings menu shows 0% under Energy. I installed the PowerSupply app, but all the fields are displaying "N/A." I've checked to ensure the battery is properly seated and that the phone turns on when unplugged. I can't find any information about this issue. Has anyone else experienced this or know what might be causing it?

I'm still working full-time on my educational bare metal OS project for the PinePhone.  Zig has been a great match for this project, and with a sprinkling of arm assembly, the OS is now booting in 800ms!  Who needs modern hardware   

Anyway, I'm almost at the point where I can add some basic Apps, and then I'll have to think about distribution to a couple of colleagues for testing.

First I need to ensure my OS can only boot on the PinePhone v1.2b, since that is the only device I have for development.  Does anyone know if there there is a version string somewhere within the hardware?

The other unknown is U-Boot.  It seems to do a lot of the hardware configuration before it reaches my kernel code, and I am a little concerned that people might be running different versions from me (U-Boot 2020.07).  Currently I'm running from SD card, but maybe the boot process/chain is different once I figure out how to install my kernal onto the eMMC?

Do we know how many v1.2b devices were sold? and how long they will stay in production?  Since that obviously limits the scope of my project.  The device I have is continually out-of-stock, maybe already discontinued?  And the expensive model is currently $270, which is a bit of a worry when I see android 14 phones going for 79eur.  Are the PinePhones still selling?

Anyway, whatever becomes of this project, I wanted to thank the community for their support over the past 2 years.  It's a shame I didnt discover the PP sooner!  I was hoping to add LORA and Keyboard case support next, but just discovered they are no longer available

Just thought if anyone was thinking/trying to use a rock64 to control their 3d printers with Klipper / Mainsail over serial, that this might help
I did this with four rock64 v3 and got everyone working exactly like my pis, controlling 2 Prusa MK3S each.
I am not a Linux user, I managed to piece this together for the first one and the other 3 went smoothly following this.
Some of these steps may be redundant or unnecessary, but the result is that it works.

Base Setup:

Wipe SD card with SD Card Formatter
Download and use Armbian Imager to image SD
select board and OS
I used OS Minimal 25.5.1 bookworm

sudo apt update && sudo apt upgrade
sudo apt-get install git -y
sudo apt install network-manager
sudo reboot

Set up wifi dongle: (you may need specific firmware for brand if not Linux native. Mine was, I used a Ralink dongle)

nmcli device wifi list
nmcli dev wifi connect "Your_WiFi_SSID" password "Your_WiFi_Password"
nmcli device status
sudo reboot


Setup Mailsail and klipper, just follow prompts to install 1-3 or follow a guide for Kiauh:

cd ~ && git clone https://github.com/dw-0/kiauh.git
./kiauh/kiauh.sh
(install 1, 2, and 3)
sudo reboot
sudo apt update && sudo apt upgrade


Reduced bootup time for no Lan connection from 2min to 10 sec:

find / -name "systemd-networkd-wait-online.service"
(This should be the location, but confirm with the find)
sudo nano /etc/systemd/system/network-online.target.wants/systemd-networkd-wait-online.service

(add text under [Service])
TimeoutStartSec=10

(At this point you could run klipper over a usb to the printer
Mailsail/klipper web GUI is whatever IP the rock64 or wifi dongle grabs
It will be at the top of the screen when you ssh/login)

Tx/Rx setup on UART2/tty2:

sudo apt update && sudo apt upgrade

1.Overlays
sudo armbian-config
system>kernel>boot01
(added text to boot/armbianEvn.txt under overlay)
overlays=rk3328-uart1 rk3328-uart2 rk3328-uart3

2.Kernel
sudo armbian-config
system>kernel>ker001 - alt kernel
updated to the newest rock kernel

3.disabled console
sudo systemctl mask serial-getty@ttyS2

4. Added users to dialout group
sudo usermod -a -G dialout <username>
(confirm user is in dialout group)
groups

5. echo test with jumper if you want(jump the UART2 Tx and Rx pins(8,10) together with a wire, no ground needed)
sudo apt install picocom
sudo picocom -b 115200 -r -l /dev/ttyS2

Type anything, if writing appears port is working
ctrl a then ctrl x to exit

In your printer.config file under the MCU you will use
serial: /dev/ttyS2


Happy Printing!!!
