It appears that nearly all USB 3 supporting devices I try won't work on the type-A USB 3.0 port of the Pinebook Pro. I believe this is a power draw issue from what I've read, although it doesn't entirely match up with what I'm seeing.

• TP-Link 1G Ethernet adapter - Left port: "Cannot enable. Maybe the USB cable is bad?". Right port: Works as a USB 2.0 device.
  
• WD My Passport 2.5" spinning disk - Left port: Half-spins up, clicks, spins down, repeat. Right port: Works as a USB 2.0 device.
  
• Inateck disk enclosure with SATA SSD disk - Left port: Works as a USB 2.0 device. Right port: Works as a USB 2.0 device.
  
• Some generic SD card reader - Left port: Works as USB 3.0 device! Right port: Didn't bother trying.
  

Hello,

I am currently running Tow-Boot but I noticed similar behavior with U-Boot:
- If I reboot, and try to select boot from SD - it fails, sometimes it freezes or fails to detect the linux image
- If I power cycle - most of the times I can boot from SD.

With U-boot it was similar, after a reboot, only boot from emmc was possible. But if I powered off/on, it would boot from SD.

Is this intended behavior?

Hello all,

Two issues with audio on PBP that I see no way out of:
- the audio jack: when plugging in headphones with a TRRS plug - the mic is not detected, only the speaker function(someone on discord told me it might be related to alsa ucm2 - maybe because there is only a "High fidelity audio" profile available or something like that?)
- The internal mic picks up a TON of noise, messing around with the controls in alsa can reduce the noise, make it almost functional. If the audio jack mic would work then this is almost a non-issue, I do not want to use the integrated mic anyway.

I tried a bunch of distros - armbian, manjaro, arch(still working on it), kali - none of them have a properly working audio system.

Am I missing something obvious? Could my audio jack just be poorly wired or something?

P.S.
Also the popping and the hissing of the audio.... that has been reported by other users as well. I dealt with it by disabling suspend and switching to headphones(even if disconnected).

Hello,

The Pinebook pro webcam doesn't work either in Cheese or Kamoso with the preinstalled Manjaro, and it's definitely not a privacy switch issue as replies all over this forum suggest.

It actually works with any of these :

mpv /dev/video4
vlc v4l2:///dev/video4
guvcview-qt -d /dev/video4

It also works with webcamoid - that needs to be built from AUR although.

And it also works in a Jitsi echo test in Vivaldi : https://janus.conf.meetecho.com/echotest.html

However, the Webcam works out-of-the-box with Cheese using either Armbian or Twister OS (Both based on Ubuntu LTS), so I wonder what library or helper might be missing in Manjaro to get it working.

I tried to search for a while, but to no avail so far.

Any clue would be much appreciated.

Hi Mobian forum,

I'm trying to get my Pinephone into a state in which it suitable as a daily driver. I've updated to the latest version of Mobian and most things work most of the time (I do need to boot while the phone is plugged into the USB port to get the phone part working). The main blocker at the moment is that I can't receive MMS. I will send one to the phone but no joy, then after I reboot I get the message: You received an MMS, but it expired on: 1970-01-01 07:59

Any ideas?
This is with Telstra (Australia) and the UBPorts edition of the Pinephone.

Hello, this is my first time here. I received my Pine 64 a week ago and it powered up just fine. After getting familiar with the os that came with it I decided I wanted to try Mobian. After creating the jump drive and after installing the new os the battery had died. It was not charging in the phone so I bought an external battery charger and was able to fully charge the battery. I put the battery into the phone and it does not power up. I am at a loss as to what to do next. I have been wanting this phone for a long time and now its a brick. Can any one advise me on how to get this phone working again?

Hi,

https://wiki.pine64.org/wiki/ROCKPro64_Software_Release reports the possibility of installing debian on the ROCKPro64 using the Official Debian Installer via the installer image to be found at https://deb.debian.org/debian/dists/bull...rd-images/

I have verified that the installer image boots and does its job of downloading and installing stuff.  However, installing (at least installing on the EMMC) delivers a system incapable of booting.

I now wonder if this is because the official debian installer does not install a bootloader and expects a bootloader to be already present on the SPI.

If this is the case, the page at https://wiki.pine64.org/wiki/ROCKPro64_Software_Release shouild probably say so.

I have tried to install tow-boot on the SPI expecting it to be the best option for a general bootloader.  Unfortunately, It does not appear to work. After coming up, it hangs at

Hello,

I was following this guide to utilize my new NVMe drive.

When I flashed the eMMC from an SD boot, everything seemed to go well.

After shutting down, it will no longer boot. If I hold the power button for 20+ seconds, then press the power key, the red LED flashes but nothing is happening after that.

I've tried booting from the SD with and without the eMMC installed. I've also tried flashing the eMMC with the USB adapter.

I thought flashing the eMMC was a safe operation to perform. Am I missing something.

Any help is appreciated.
