The PPP behaves as if the volume button is pushed all the time, how fix?

Posted by: guru - 08-31-2025, 04:39 PM - Forum: General Discussion of PinePhone Pro - Replies (2)

Hi all,

Recently I made the brave attempt to upgrade my PPP bought before 2023, with RK2AW.

The point with installing RK2AW is to get decent behavior in case of battery depletion - before RK2AW, if you deplete the battery, the phone would go into a battery-depleting perpetual loop and the only way to get the phone working again was to remove the USB and battery, push the Maskrom/RE PIN, and then boot the phone, and leave it like that for 10-20 hours.

For RK2AW distribution, I took this archive https://xff.cz/kernels/bootloaders-2024.04/ppp.tar.gz , as suggested by the Pine wiki https://pine64.org/documentation/PinePho...ion_image/ and also by Megi in his blog https://xnux.eu/log/098.html .

The installation steps were really only:

Code:
sudo bash

cd /root

wget https://xff.cz/kernels/bootloaders-2024.04/ppp.tar.gz

sha256sum ppp.tar.gz

tar xvfz ppp.tar.gz

cd ppp

./spinor-flash-initial-setup.sh

And the outcome of this was that RK2AW with the "RKBIN" closed-source memory initialization blob + a recent U-Boot had been installed.

After that, I powered off the PPP, and disconnected USB and battery for 30 seconds. Not sure if all those steps are really needed but, after that definitely RK2AW worked as expected.

The issue came when I booted up PostMarketOS Edge with this new RK2AW-flashed PinePhone Pro:

The phone kept behaving as if I had tapped the volume up or volume down button, while I had not.

And meanwhile, the phone when in PostMarketOS stopped responding to when I actually pushed the volume button up or down.

I'm not sure if the issue is that I stopped using Tow-Boot and use U-Boot now, or if the issue lies in RK2AW.

Googling and asking Perplexity AI, I see that other people have had the same issue.

The quick fix is to disable the OS' event logics for when you push the volume button in the first place.

But, I cannot find any concrete suggestions for this fix.

I have also seen PostMarketOS insert gibberish in both directions into the UART data. It is so bad that the UART at least periodically becomes unusuable, because new gibberish is pushed every second, and often the gibberish is interpreted as special key combinations, that make you get logged out.

I saw some suggestion that at the root of this is a driver issue, so it sounds like it's fixed by including a particular Linux kernel patch into PMOS.

I tried with the latest PMOS Edge dated 20250830 and the problem is there too.

Did anyone have this problem too, can you share exactly how you fixed it?

Do you know any Linux distribution for PPP which has fixed the issue?

Any insights appreciated.

A few questions before I jump in

Posted by: L67GS - 08-30-2025, 11:32 PM - Forum: General Discussion on PinePhone - Replies (4)

Apologies for starting in this sub-forum, I didn't see an "introductions" section.....

I'm a Linux user since 1998, but admittedly not a real "power user", every computer I own is Linux based, but I have to use an abomination at work like most people.

I have several years experience with SBC's and a healthy collection of them. As far as coding goes I know some C++, and know enough to do fun stuff, but I'm not a developer by any stretch of the imagination.

I'd like to order a PinePhone, and use it as my daily but I really need to know a few things before I do. I read through the forum some, and watched some YouTube videos but we all know how quickly things change and I didn't see anything super recent about my concerns.

It's understood that PinePhone is under development, and there are going to be quirks and plain old "don't work for that" scenarios (like everything Linux), so I'd like to see a baseline of what IS happening before I commit....

I'm not only open to trying different distros, but enthusiastic about it, so if one is better at giving me the capabilities I need than the others that's great!

The things I need from a phone are:

1) 5G phone service on T-Mobile (USA)

2) RCS chat

3) WhatsApp

4) FireFox, or a secure browser that isn't going to get blocked by places like my bank, preferably NOT chrome

-------------------

Also I'm curious what development environments can run, my go-to is Geany, and I've also just barely started dabbling in front ends so I'm curious what's supported, QT or something?

And I'm assuming there's a way to encrypt a folder and make a safe place for sensitive storage like LUKS?

Thank you for reading, I'm really excited to get some feedback, if I can do the 4 things above I'm ordering a Beta,I've looked at the Pro, but it's out of stock.

Goolge banning Sideloaded APKs in 2026, Year of the really Linux Phone?

Quote:Given what Google just announced, I think that Linux phones are going to get very very popular very very soon. Does anyone here have experience moving from Android over to the pine phone? I use a lot of FOSS that Google really doesn't like and their policy changes coming in 2026 don't bode well for me. App developers on GitHub, F-droid anything not officially verified by Google or rather the developers of those apps are effectively going to be banned off of the ecosystem.

Just looking to pack a parachute.

Someone who uses Reddit should link back to this thread.
There is much misinformation, according to this thread a standard Pinephone is priced at $800 but only worth $200; the only available OS is Postmarket, and some feel the PP is a joke.

What's stopping you from daily driving the PPP?

Posted by: teekay - 08-22-2025, 11:58 PM - Forum: General Discussion of PinePhone Pro - Replies (15)

For those who have a PPP gathering dust in a drawer somewhere, what's stopping you from daily driving it? When I got mine earlier this year, I tried it out and made a list of things that stopped me from ditching my Android for it, which was:

Need physical protection (cover). I looked around for other phone covers that could work for the PPP, but eventually got the PPP TPU cover. I wish it had the corner bumpers as well as extending over the front screen for better protection, so I'll keep looking for alternative covers.
The biggest issue was battery life. Using Mobian, suspend worked, which helped, but I could barely browse the web for 1 hour before the battery meter dropped from 100% to less than 30%. YouTube went from 100% to 5% in under 30 mins! Luckily I discovered this is a software problem rather than hardware, hence my efforts to patch the kernel to fix the battery meter (see other threads), which is now working quite reasonably for me.
A semi-working camera so I can document things or scan QR codes (not worried too much about quality). This is working now.
Less of an issue: an offline GPS app for my camping/hiking trips. There are some options now (not all mobile optimized yet) like Organic Maps.

After the battery fix (still WIP), I've been able to daily drive the PPP for more than 2 weeks now without once reaching for my Android. I am surprised at how many things I use that works great:

Calls and SMS
Bluetooth audio playback
Bluetooth keyboard for some terminal usage
Software updates (and some great apps on Flathub like Foliate, Cozy, Papers, Telegram, Delta Chat)
Web browsing with Firefox + uBlock Origin
Media playback (videos, audiobooks, podcasts)
Reading e-books
Contacts/Calendar sync with my Nextcloud
Alarms work even when the phone is suspended
General reliability, i.e. phone doesn't randomly reboot or heat up in my pocket, etc.

There are still a few bugs I'm logging and hoping to either file an issue or fix myself, but nothing too serious. So the PPP might be discontinued, but I feel like it's just come alive for me! I ordered a USB-C dock so I can try out the convergence feature (there's a YouTube video of a guy doing web dev on this PPP like this and it has me excited!)

So if you've got a PPP and you aren't using it, what's stopping you?

Multiple NEMA 17 stepper motors with the Teensy 4.0

Posted by: Harry - 08-22-2025, 12:24 AM - Forum: General - No Replies

	Good afternoon everyone, I'm working on a project that requires six NEMA 17 stepper motors. I can use the standard A4988 or the more powerful DRV8825 driver, but both are 5V devices, while the Teensy 4.0 is a 3.3V device. Can these drivers be used directly with the Teensy without damaging it? Do they require a logic level converter? Are there other compatible 3.3V stepper drivers?

Giving away a Pinebook Pro for free (with a broken hinge)

Posted by: tuxifan - 08-20-2025, 03:59 PM - Forum: Pinebook Hardware and Accessories - Replies (4)

Hey!

The hinge on my Pinebook Pro has broken and I don't feel like fixing it. And since I'd hate to throw this thing away for just that reason, I'm willing to give it away for free.

I'm shipping from Germany near Hamburg, just send me a message here or on IRC (same username as here) if you're interested. You would however have to pay for shipment, after successfully receiving the Pinebook Pro.

Fixing that hinge apparenly involves gluing it, for more info post a message in the #pinebook channel on the Pine64 IRC, it appears to be pretty repairable using the correct type of glue.

Tell me what you're going to use the PBP for!
This is how I'm going to rank this:
1. Developers - reputable developers in the Pinebook Pro community who need some extra hardware to play with and don't necessarily need a working hinge.
2. Newbies - people interested in buying a Pinebook Pro and in fixing that hinge.
3. Enthusiasts - existing Pinebook Pro users interested in spare parts and willing to distribute remaining spare parts further.

If you're a developer, send me a link of some sort to a list of previous contributions.

fixing the ppkb mainboard rather than replacing...

Posted by: Jite - 08-16-2025, 02:20 PM - Forum: PinePhone Pro Accessories - Replies (2)

Dear all,

I was hoping to brain storm the community on how to fix the pinephone keyboard mainboard rather than just replacing it when the charging chip overheats and gets fried as it seems to do every 4-9 months for me.

I must have at least 6-7 mainboards in my possession now (only one of which is working sadly).

I have never soldered before, but would be willing to learn, particularly if the replacement charging chip could be bought for very cheap and it just needed desoldering the old one and soldering on the new one. This would be a good reason to start my soldering journey...

Glad for anyone's tips on this.

Pinephone pro stuck while booting

Posted by: Supervisor - 08-16-2025, 11:35 AM - Forum: PinePhone Pro Hardware - Replies (3)

So i have a pinephone pro and i have tried every thing provided here https://forum.pine64.org/showthread.php?tid=18216 and gotten assistanve on discord which still did not help. Ive charged for approximately 10 hours on Maskrom, tried using a sd card, flashed directly to EMMC, attempted to reinstall Towboot, Used a gui tool and dd, and still it will not work. Whenever i turn it on with a working os installed it will flash red then yellow then stay stuck, the screen wont even show anything. If i try without an os on the phone it reboots as the it knows there no os installed. Sometimes too when i turn it on it will stay red and just vibrate as soon as it is turned on. It will not even boot to an SD card if i use either the RE button or the volume down button. I can however boot into mass storage mode by holding volume up and connect it to the computer, im not sure how much this can help but if anyone can help pls do.
