  Vertical Grey Bars on PBP Reboot
Posted by: MickTheGeek - 05-18-2021, 09:41 AM - Forum: General Discussion on Pinebook Pro - Replies (5)

Hello all.  I'm still having problems when I reboot my PBP.  When I do, I get a screen with grey vertical bars and it just stays in that state until I shut it off with the power button.  I posted back in October of 2020 when I first started having this problem, but the only solution available at the time was to just do a shutdown and power back on the machine to restart it, and a kernel update or fix would come it the future.  Is there a fix for this issue, and if so how do you fix it.  I have a PBP ANSI running up to date Manjaro.  Any help/info is appreciated.  Thanks.

/Mike


  chats not working
Posted by: rvh - 05-18-2021, 07:48 AM - Forum: Mobian on PinePhone - No Replies

the last time this happened the only way to fix this i could figure out was to reinstall the OS. thats kind of a nuclear option. Is there any other way to get it working?


  no 911

i had to call 911 and to my surprise, the call wouldnt go through. Is there a way to fix this?


  I am ready to accept that there may be a problem with my emmc.
Posted by: djhnsn - 05-17-2021, 07:53 PM - Forum: General Discussion on Pinebook Pro - Replies (4)

At first, I was convinced it must be something else, because my uboot and intitramfs load. I thought my uboot was doing something wrong. 

However the latest uboot, gives an error definition for the error 110 that I have been getting.
emmc not responding to voltage select.

If you look at the output of this uboot, you will see that regardless of the error, it still finds initramfs. 
After that finishes, if I click the arrowkeys on the manjaro boot menu I get hit with error 110 4 times and that's the end. 

Clearly there is some kind of problem that doesn't matter if it does happen to boot. 
Does customer service respond to this forum? If not, where can I open a ticket?

On another note, does anyone know of an alternate emmc that could work that I can get shipped quickly from amazon?
There are several on there, but I don't think they are all the same. 

Pictures of uboot and post uboot attached.

  PWM whine near earpiece in low signal phone call and loud sound sent to the other end
Posted by: vortex - 05-17-2021, 05:47 PM - Forum: PinePhone Hardware - Replies (29)

For reference, my phone is a Beta Edition Convergence PhonePhone (1.2b hardware). I am running Mobian with the following modifications:

  • Running 5.11 kernel
  • Flashed the anx7688 with the latest firmware
  • Installed crust-firmware package
In all of this, I was calling a land line.


Today, I had my first chance to see the PinePhone in action with phone calls in a location with very poor reception. Many places there have no reception. Many other places a phone has to drop to 2G. 4G in a few places, though it is marginal. This was the pattern with my old phone (Nexus 5), and is the pattern with my new PinePhone. At first glance, it looks like my PinePhone is doing a bit better reception wise than my Nexus 5.

Yesterday, I called the landline from a location with good reception and there were no problems. I also did the same earlier tonight at the same location to check, and had no problems.

But in the location today with bad reception, there were major problems that were strongly correlated with the reception.

On my end, there was a loud sound coming from inside the PinePhone case near the earpiece. The sound seemed like PWM whine. So I think it is a switching power supply and a capacitor combination. It quite bad in one location. I moved to another location with better reception and it decreased some. I ended the call and tried again in a location outside with slightly better and the sound was a lot quieter, and I could make it slightly quieter by rotating myself so it would aim in certain directions. My Nexus 5 makes a similar sound but much quieter even in poor reception, and has a similar pattern.

On the other person's end was much worse. They said a very loud sound was coming through on their end which made it even harder to understand me than the sound on my end made it hard to understand them, though my voice was coming through better than on my old Nexus 5 except for the added loud sound. The intensity of the sound decreased as the signal quality improved. From how they described the sound later, it seems like it might have been RF pickup in the microphone line or the sound connection line to the modem. Tomorrow, we are going to attempt to record the sound on their end so I can listen to it and try to figure out more.

Based on the pattern, I think that the sound on my end and the pickup causing loud sound to be transmitted to the other end are due to the increased transmission power as the signal quality decreases. In the worst reception area, the modem is operating at maximum and the problem is at its worst.

For the PWM whine on my end, I am doubtful there is a software solution. Only possibility would be if the PWM frequency is controllable from software. But the PWM whine on my end isn't too terrible (it is tolerable). For the noise transmitted to the other end, it is possible that the settings of the modem, CPU, and sound hardware may have some tangible effect; but I don't know. There is more likely to be a solution, though than for my end.

Hardware wise, assuming I am not the only one with this problem and that the electronics causing it are not inside the modem itself, it might be possible to reduce by finding the particularly switching supply and changing it to a different one as well as changing the capacitor to one that will make less noise (hopefully the capacitor is easy to get to because then it would be possible for the brave to desolder it and solder a new one on). That by itself my reduce the problem to no longer be an issue. The RF pickup can probably also be reduced in other ways.

Anyone have any ideas on this and/or have experienced it?


  Fraud Warning on purchase attempt?
Posted by: kriscj - 05-17-2021, 10:28 AM - Forum: General - No Replies

Hello, Pine community.  

I attempted to buy a pinephone this weekend (mid-May, 2021) using my credit card and was declined, and knowing my finances are OK, asked the bank the reason for the decline.  They stated that the purchase was blocked because the vendor has a history of fraud reports against them.

Now I'm not sure what to do... I could probably go through PayPal, but SHOULD I?  I love the idea of the pine universe of devices and am an IT guy, so I'm a good early adopter, but this fraud warning has me really worried.

Interested to hear your experiences and opinions on the matter, please?


  OpenBSD 6.9 install
Posted by: StickyPine - 05-17-2021, 02:30 AM - Forum: BSD on Pinebook Pro - Replies (18)

Hello,

I attempted to install OpenBSD 6.9 on the PineBookPro. I essentially followed those steps https://github.com/ndhwyd/roc-rk3399-pc_openbsd and changed rk3399-roc-pc.dtb with rk3399-pinebook-pro.dtb. 

When starting the machine, the booting process halts with the following message:

Code:
bwfm0: failed loadfirmware of file brcmfmac43456-sdio.rockchip,rk3399-evb.bin

(I have the same issue when using rk3399-roc-pc.dtb)

Has anyone experienced something similar or would know how to solve this ?


  are you supposed to be able to remove & put back the keycaps?

Hi,

Before I pull on them and maybe break it;
Are you supposed to be able to remove & put back the keycaps of the Pinebook pro?

If so; just pull on them?


  PINE A64 AUDIO DAC POT BOARD On A64 LTS w/ Armbian FOCAL
Posted by: A64mediaplayer - 05-16-2021, 11:43 AM - Forum: SOEdge Hardware - No Replies

Hi Folks!

Setup an A64 LTS board with Armbian focal and trying to get the Pine DAC POT running.  Any insight into the method to make this work? 
Is it via dt-overlay like in raspian ... or something else?  I am assuming this is possible since the Volumio image claims to work ...

Thanks!


  no unlock screen (plasma mobile)
Posted by: dieselnutjob - 05-16-2021, 08:39 AM - Forum: Manjaro on PinePhone - Replies (6)

I just reflashed Manjara plasma mobile and then did pacman -Syu
Now I can ssh into the phone but I can't get an unlock screen to appear.
If I reboot the phone sometimes the unlock screen briefly flashes on just before the KDE start logo think.

What should I do?
