I asked in pine64 support and they said everything is fine and to ask here. Basically I have two different usb hubs one is an anker and one is a kind of no-name brand one. Neither work with the pinetab2. I plug them in and they make a concerning humming sound and no device actually works on them. Are there certain hubs that are known to work? The issue is that with using an wifi dongle it monopolizes my USBs and then I can't use a keyboard and mouse so I was hoping to use a hub to give me more ports. 

Thanks!

I'm getting rid of my 2020 PinePhone Manjaro CE EU, so I'm offering it in this forum first.

I used it for a few weeks, found a few software issues (see my other threads) but other than that it did its job (of convincing me that it was not ready to be my main driver). Shortly after buying it though suddenly it stopped booting and honestly I didn't have time to reinstall the whole thing, so I stored it and never looked back.

If you're interested please name your price below. Shipping costs are on you.

If there are no responses in about a month, I'll dispose it somewhere safe.

Happy New Year! 2024 is here and we’re running Apache NuttX RTOS (Real-Time Operating System) on Single-Board Computers with plenty of RAM. Like Pine64 Ox64 BL808 SBC with 64 MB RAM!

In this article, we create a Blinky LED app with a Python-like, Garbage-Collected Language that compiles to C: Nim Programming Language.

Garbage-Collected Languages (like Nim) require a bit more RAM than Low-Level Languages (like C). Perfect for our roomy (and vroomy) SBC!

(1) We test NuttX + Nim Blinky on QEMU Emulator for 64-bit RISC-V (minus the blinkenlight)

(2) Then we run NuttX + Nim Blinky on the Ox64 BL808 RISC-V SBC (with a real LED)

Hello, Where can i find component's layout scheme ?
I need it for repair.

Sorry if this has already been asked. I put Ubuntu Touch on an SD card and booted successfully. I enabled WiFi but it did not see my network. I manually added hidden network info with no luck. I am using the same wifi adapter setup I use with the stock OS which works well. If I need to direct this to UB Ports I will.

Oddly enough if boots from the SD card without using the UART adapter I purchased because my PT2 did not come with one. Purchased off eBay so original owner may have not seen it and accidentally discarded it.

I bought a PBP over a year ago and installed ArchLinuxARM on it. After initial install I could not make a wifi connection and was too busy to troubleshoot thoroughly. I've come back to it a few times since, but soon give up because screen is on low brightness and the adjustment keys don't work and I remain too busy to find the actual headache this produces worth going into.

Basically, no interface shows for wifi besides lo. I've tried device list in iwd, ip link, and looking direct at /sys/class/net. I've checked that the privacy switch for wifi is not blocking it, and get two blinks from the numlock light.

I thought I would just try a reinstall from scratch, but when I go into BIOS at the start (UEFI?, tow-boot?) and select USB it will not boot from the drive I have installed there. Installation instructions say any version of tow-boot should work for an install, and the version I have is the one released before the current one.

Where should I be looking for the wifi card? Instructions talk about USB or PCI, but the wiki says the adapter connects via SDIO?

I searched through the forum but could not find my issue. Anytime audio is called for, my Pinetab2 produces what sounds like static on the AM band from the speakers.  The speakers do play sound, but below 25% audio all you hear is the static. If you turn the volume above 25% then you can begin to hear the audio over the static noise. The Pinetab2 also makes the static noise while booting but I assume that there must be some kind of a boot chime or sound that is calling for audio and it just plays the static. If you dont have any system calling for audio the static noise will stop after about 20 seconds until the next time there is an audio event. I can insert a 3.5 mm headphone and turn off the speakers and the audio through the headphone is clear.I have also loaded Ubuntu and Rhino linux onto an SD card and booted them with the same issue. 

Anyone else had this issue and resolved it?

For over two years, there have been many scattered posts from people wanting
to be able to use their phones to make and receive calls using hands-free
bluetooth devices. This has been standard with android phones for well over
10 years.

From what I can see with pipewire and wireplumber, and from what others have
said, it is just a matter of creating the proper audio profile
(pipewire/wireplumber configuration) to route the audio between bluetooth and
the modem. If there was proper documentation of the relevant systems I would
figure it out myself and post the solution here.

There are certainly people who understand pipewire/wireplumber well enough
that it would be fairly straightforward for them to solve this problem if
they thought it worth the effort.

I will give $50 to the first person or project (Mobian for example) who,
before June 1, 2024, will come up with a solution compatible with hfp 1.5 and
later, and make it publicly available in a way that the common pinephone
(original) user can make use of it. This could be somthing like an
installable package or upgrade to a package, a script to make changes or, if
it came with complete step-by-step instructions, as a set of edits to
configuration files.

I realize $50 by itself might not be enough motivation so I would ask those
who also need this to at least register their desire for it by taking the
time to add a post to this thread, and for those who can, by also offering
additional money.

Maybe someone with the knowledge just needs to know that people need this.

Hi everyone!

I'm about to sell my Pinebook Pro because it annoys me too much due to it's design flaws. It's barrel port does not charge the battery (propably some part of charging circuit has fried). However when laptop is powered on through barrel port, without battery, with bypass connected it does power on and at certain point shuts down (probably fried IC causes too high power draw). On battery Pinebook Pro boots and works without any issues (well, kind of).

Issues that annoy me:
- very slow charging through USB-C (when disabled it takes about 4 hours to charge from empty to full),
- annoying noise from speakers when audio codec wakes up,
- when playing loud music speakers cause voltage drops and disconnects USB buses (including keyboard and touchpad).

Details about the laptop:
- updated touchpad/keyboard IC: touchpad works perfectly and very precisely better than in ASUS Chromebook C201PA (which I still own),
- installed official U-boot (master branch, compiled by myself in August 2023),
- installed Devuan unstable with XFCE (mainline kernel 6.5.8),
- configured suspend mode as s2idle because from deep sleep it never wakes up (should try linux-rockchip branch on kernel.org),
- probably part of charging circuit has fried, USB-C charging works without issues (except that it is slow), DC barrel charging and USB-C charging works without issues, original DC barrel adapter was faulty,
- case without cracks or any other noticeable damages case has cracked under USB ports (another typical design flaw of this laptop), no other damages,
- manufactured in April 2022,
- full battery can last around 5-8 hours of web browsing, source code editing

I want to sell it for 170 euros.

If nobody will be interested I will throw it's battery to trash and design my own power supply circuit with battery rated at 7.6V to eliminate all stupid design flaws mentioned above

I've had my phone for over a year and several months ago it started omitting every 4th or 5th row of pixels, all down the screen. This makes text look unsmooth and as if it was made of lines. It also does a strange ghosting type thing where it continues to display blocks of the last pixels displayed. It's much more noticeable on black areas of the screen.

Currently, I'm running Arch Linux on it (phosh), but it's the same with Debian phosh and Debian plasma-mobile and some other OS I've tried.

The bizarre thing is that it seems to be perfect at times, but will then all the sudden start ghosting and omitting rows of pixels. This often happens during boot up. Once it happens, it tends to not go away.

I will say that I have used the phone in my bath though have never gotten water on it, but it has been exposed to humidity, so maybe that's it? Never had a problem with any of my other devices doing this. Right now I've put it infront of a heater to see if just maybe there was some residual water in it that could be evaporated.

Otherwise, the phone is perfectly fine; touch works perfectly, it's just as fast (or slow :p ), and I can take calls...

I'll send a picture of it in a week or so, as I've finally caved and bought an Android phone so will have a decent camera.

Also, I've not done any tweaks to it, such as over-driving the CPU or whatnot.

Any ideas or similar experiences?
