  keyboard problem
Posted by: romansvec - 11-04-2019, 03:43 AM - Forum: Pinebook Pro Hardware and Accessories - Replies (12)

Just got new Pinebook Pro and after first testing I realized the laptop keyboard is so bad I cannot write on it. I have to press key couple of times to type 1 single character. It is impossible to use such keyboard. It seems to be HW issue as when I attached external keyboard it worked fine.

How can this be fixed?


  reboot / crash
Posted by: Der Geist der Maschine - 11-03-2019, 09:42 PM - Forum: General Discussion on Pinebook Pro - Replies (40)

My Pinebook Pro was running for several hours. I left for an hour or so and when I came back, it had rebooted.

The systemd journal is not in persistent memory and so I don't know what happened right before the reboot or crash. All other logfiles in /var/log/ don't show anything in the 30 min before the reboot / crash.

Anyone has seen a reboot or crash, as well?


  How free actually PBP is ?
Posted by: as400 - 11-03-2019, 01:56 PM - Forum: General Discussion on Pinebook Pro - Replies (9)

Hello to everybody as this is my first post.

I was wondering how free actually PBP is ? I know that there is one blob needed for booting and another one for BT/WiFi. Anything else ?

I am asking this question being not very familiar with arm devices in general.


  Best distro for kodi with web browser
Posted by: vecnar - 11-03-2019, 11:53 AM - Forum: General Discussion on ROCKPRO64 - No Replies

Hello,

I have openmediavault nas running on one rockpro64 and i got second one as a backup but rather than laying on the shelf thought to use it as fire tv stick replacement in one room. 
Below are the things i tried:

  • Libreelec is great but lack of web browser is a big disadvantage as i have wireless keyboard with touchapad. 
  • Tried android 9.0 in hope to find and install some type of ui installer for and be able to control with hdmi cec but failed due to ethernet not working and i do not have wifi adapter.
What linux distro would you recommend that has some ui for remote control, quick to boot, kodi compliant, chrome compaitble and microsd card safe?


  LuneOS November Stable Release: Eggnog Latte

Here's some recent news on LuneOS: https://pivotce.com/2019/10/24/luneos-oc...nog-latte/

This is a general news release (not specific to the PinePhone) on the latest OS release.


  Pinebook Pro - No Audio
Posted by: bebop_man - 11-03-2019, 09:01 AM - Forum: Pinebook Pro Hardware and Accessories - Replies (13)

After I finally got it powered on, I I tried playing both a short movie, a youtube video, and a local MP3 file.  No audio from any source.

I did confirm the volume is 100%, not muted, and using the es8316-spk-sound device, output to the analog stereo output.

Test speaker buttons also make no noise.

I don't get anything from the onboard speakers or the headphone jack.  I haven't played with the UART switch yet as my understanding is that only affects the output of the jack itself, and not the onboard speakers.

apt update and apt upgrade have been run from the root logon.

Any suggestions?


  Overclock past 1.8/2.2
Posted by: kolbycrouch - 11-03-2019, 01:20 AM - Forum: General Discussion on ROCKPRO64 - Replies (3)

Hi everyone! I've been testing overclocking on the rockpro64 for some time now, and I've gotten a stable ( I think ) overclock of 1.8/2.2 for the little and big cores.

However, when trying to push them any higher than 1800000000 and 2208000000 in the dts for ayufan-linux-mainline it never works.

I can attempt to set the big core to anything I'd like ( 7.0ghz ) and I get no real warning, and the clock as reported by sysfs is still 2.208ghz

I had to crank the voltage up a good bit to get them stable at this freq anyways so I'm not sure how much further I could go, but I'd like to try.

The thermals with 20mm heatsink + fan are still well within reason too.


  Can I rewrite a non-bootable eMMC from the PBP itself?
Posted by: Kicou - 11-02-2019, 03:35 PM - Forum: General Discussion on Pinebook Pro - Replies (3)

I was playing with different OS images and decided that since I was able to successfully boot from SD card it would be OK to overwrite the eMMC module image.

I dd'ed a Rock64Pro (bionic-minal arm64) onto the eMMC and now it won't boot anymore, neither from eMMC nor SD.

I was able to eventually start from SD by disabling the eMMC via the internal switch, but since I can't see it I cannot write to it.

How can enable the eMMC but bypass it at boot in order to rewrite it from the PBP itself (I don't have any other equipment to which I can attach the eMMC).

I have enabled the serial connector and do have a serial console adapter that I can connect to a Linux box, and probably attach to via minicom.


  Horrible screen flicker/strobe on battery power
Posted by: mattjb - 11-02-2019, 03:18 PM - Forum: Pinebook Pro Hardware and Accessories - Replies (19)

Moving my information to its own thread here from the General Discussions forum as it seems like at least one other person is having the issue too. I'm thinking it is hardware related as it happens on bootup before it hits any graphical intensive tasks or a desktop. I can only adjust the brightness when  in desktop mode though, as it seems to be handled through the power management application.

Quote:I'm experiencing the exact same issue as Meatball regarding the flickering screen when on battery. When on AC power, it's fine, but as soon as I unplug it, any graphical related activity (even moving the mouse) causes random massive headache-inducing flickering. It seems to get worse as time goes on... It is still present with all dimming options off and happens at any brightness level as far as I can tell. I'm also hearing a high frequency whine when it switches to battery power though I haven't paid attention if it happens at different brightness levels. It's happening on both the default Debian install and on ayufan's rock64pro bionic-mate-pinebookpro-0.9.14-1159-armhf. I'll report back on other observations I make regarding this issue.

An update on the screen flicker:
Played around with the brightness a little to see the effect and here and these are my observations on brightness levels while on battery power only...
0: no coil whine, no flicker, but absolutely too dark to see anything worthwhile
1: bad coil whine, no visible flicker, usable, just a bit dim to liking
2: horrible continuous flicker/strobe - completely unusable
3: flicker but better than 2
4: a little better than 3
5: as bad as 2
6: better than 5
7: same as 6, just brighter
8: random flicker (1-2 per second), not continuous (fractions of a second) like levels 2-7
9: horrible flicker/strobe
10: worse than 9
11: worse than 10
12-22: same as 11, just brighter, completely unusable

The flicker/strobe is also visible in non-GUI applications, like when Ctrl+Alt+F1'd
For tracking purposes, battery level is being reported as 52%. I haven't had a full discharge yet.
I'm in the process of trying to drain the battery before a full recharge to see if that fixes it, just taking a while on brightness 1.
Could it perhaps be a defective battery? Any way to test this?


Thumbs Up Pinebook Pro Fingerprint Magnet
Posted by: neilman - 11-02-2019, 03:13 PM - Forum: General Discussion on Pinebook Pro - Replies (28)

I and a lot of other fine folks have noted that my/their beautiful black precious Pro seems to be a magnet for finger prints and smudges.
Only subtle mind, not blatant, however inquiring minds have to ask...

Any suggestions for the best and safest way to clean the case to remove fingerprints and smudges?
