  Pinebook pro and usb power
Posted by: pjsf - 11-10-2019, 05:37 PM - Forum: General Discussion on Pinebook Pro - No Replies

I currently use my original pinebook quite often as an off-grid media center, by attaching a usb dvd drive which I power from a largish portable phone powerbank. I intend to use my PBP this way too. It all works fine but I've noticed that when the voltage from the powerbank drops a little the dvd starts to draw power from the pinebook which really shortens battery life. Is there any way of preventing this? I suspect it's probably a requirement of the USB spec, so I don't really expect so.

I also would like to be able to run a powered hub with the PBP so I can try out some usb dvb-t sticks, will using a powered hub always have the effect of charging the PBP and hence draining the external power source quicker?

On a side note does anyone know if such a thing as a combined battery/powerbank/usb hub exists?


  USB C video and hub/net/audio/whatever
Posted by: Corkonian - 11-10-2019, 01:30 PM - Forum: Pinebook Pro Hardware and Accessories - Replies (1)

Do we have confirmed working USB C video/hub/whatever?
I would like to use my Microsoft Lumia dock, but apart from charging, it wouldn't do anything, not even the USB hub.
Since the Pinebook Pro is actually a good working computer, I wold rather travel with it than with my Macbook or my Hackintosh.
I am looking for a device that puts video to an HDMI, audio to the HDMI, charges the PBP and acts as a USB hub. If possible.
An Amazon/Gearbest/Aliexpress/Banggood link would be preferred.

Thanks!


  Always in 'Charging' state, despite being disconnected from external power

Already ran the updater.

Battery is always in the 'Charging' state despite not being connected to external power.

Persists across power cycles.


  Longer Power Cable
Posted by: Tekchip - 11-10-2019, 09:51 AM - Forum: Pinebook Pro Hardware and Accessories - Replies (4)

The power cable that comes with the device is incredibly short. Nearly useless. It doesn't reach my couch from an outlet so I can't sit on the couch and use the laptop when battery is low while it's charging. I've tried a few different USB-C wall warts and cables and while most can charge the laptop while I'm not using it they can't really push enough power to charge in a reasonable amount of time while in use.

Does anyone have recommendations for either a USB-C wall wart that can charge the laptop quickly?

Alternatively can a USB-A wall wart of reasonable power used in connection with this https://store.pine64.org/?product=2-mete...ower-cable be used? If yes, then what wall warts are others using with this cable? This cable is listed under the laptops section of the store page and it's noted it works for "Pinebook" but I don't want to assume this matches the PBP as there are a hand full of other exceptions I've seen mentioned. If this does match with the PBP perhaps this could be more explicit on the store page.

Thanks for any help or insight anyone can provide!


  Oops! I messed up the graphics drivers
Posted by: diodelass - 11-10-2019, 08:48 AM - Forum: Linux on Pinebook Pro - Replies (1)

Okay, I admit I'm in over my head a little bit here. I know messing with the graphics drivers wasn't a very clever idea this early in the software ecosystem's life, but I bear a certain curse of wild curiosity and can never leave anything alone. It's my cross to bear, but if anyone else has useful insight into what's going on with my unit, I would be quite grateful indeed.

I have ayufan's Bionic image running. The other day, I was poking around the list of packages, and I encountered three that were of interest:

Code:
libmali-rk-midgard-t86x-r14p0 [installed]
libmali-rk-midgard-t86x-r14p0-gbm
libmali-rk-midgard-t86x-r14p0-wayland

I'd previously tried to no success to get Wayland working, and here I thought - hey, there's what I need, I better install those other two drivers. So I did, and now Wayland appears to work (!) but... now a lot of other stuff is broken. Namely, sddm and lightdm won't work (the former exits with status 6), and KDE plasma (which worked fine before under X) will not start, popping up a nice little dialog box informing me that my OpenGL 2.0 is broken (when run from either X or Wayland). Xfce still works alright (using that now to post this) but the general status of the system's graphics is perplexing.

According to glxinfo, I have OpenGL 3.1 support:

Code:
% glxinfo | grep -i version

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Version: 19.0.8
    Max core profile version: 3.3
    Max compat profile version: 3.1
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.0
OpenGL core profile version string: 3.3 (Core Profile) Mesa 19.0.8
OpenGL core profile shading language version string: 3.30
OpenGL version string: 3.1 Mesa 19.0.8
OpenGL shading language version string: 1.40
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 19.0.8
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

However, systemsettings5 (the KDE Plasma system configurator) crashes immediately on startup, and most utilities related to OpenGL seem to emit a similar error that may indicate the problem:

Code:
libGL error: MESA-LOADER: failed to open rockchip (search paths /usr/lib/arm-linux-gnueabihf/dri:\$${ORIGIN}/dri:/usr/lib/dri)

libGL error: failed to load driver: rockchip


I admit I don't really know what's going on here, but it looks like something is missing. I have searched through my apt logs to see if I accidentally autoremoved something important, but I can't find it.

My real question now is simply: what do? Have I hosed it to the point where I need to reimage, or is there just some little thing missing that I can install and be on my way, or what?

Thanks in advance for whatever advice any of you might have.


  Help me understand the boot up process
Posted by: olivercfc - 11-10-2019, 08:30 AM - Forum: Linux on Rock64 - No Replies

I'm obviously missing something fundamental here.

I built an image with buildroot which creates a u-boot-tpl-spl.img, a u-boot.itb file and a root partition


Code:
        image = "u-boot-tpl-spl.img"
        offset = 32768 # 512 * 0x40 from start of sd card

        image = "u-boot.itb"
        offset = 262144 # 512 * 0x200 from start of sd card

        bootable = "yes"
        image = "rootfs.ext2"


In the rootfs partition there's a file called /boot/extlinux.conf which has the following

Code:
label rock64-buildroot
  kernel /boot/Image
  devicetree /boot/rk3328-rock64.dtb
  append console=ttyS2,1500000n8 root=/dev/mmcblk0p1 ro rootwait

This boots up and all is good.  However, I'm wondering why I can't just replace /boot/Image and /boot/rk3328-rock64.dtb (and /lib/modules/*) with the one from slack (for example) and have that boot up.

When I tried, it didn't find /boot/Image and tried to boot off the network.

What am I missing here?


  Original factory Pinebook64 bsp recently not booting
Posted by: Fox7799 - 11-10-2019, 08:25 AM - Forum: Ubuntu - No Replies

My Pinebook with factory software that arrived Nov 5, 2018 has been working with no problem (except no hdmi out) but now it suddenly will not boot. The red light at the charging port is not coming on but it apparently is getting power because the green power light comes on when I plug it in. Is there an approved fix for this? Thanks


Thumbs Down Dead in the water
Posted by: xircledev - 11-09-2019, 10:07 PM - Forum: Linux on Pinebook Pro - Replies (5)

Well... It's been three frustrating days trying to get this thing to work. It's pretty much dead in the water. Aside from being stuck in a loop when trying to boot it up, it won't turn on now. 

I followed all the troubleshooting instructions at the bottom of the Wiki. Toggling the eMMC switch, checking the ribbons, making sure the eMMC was in the socket... Nothing. It will not turn on.  Angry


  NVME not detected
Posted by: VoxUnius - 11-09-2019, 08:29 PM - Forum: Pinebook Pro Hardware and Accessories - Replies (4)

Guys, I've seen someone managed to get NVME working. My one doesn't work no matter what I do. I tried all possible OSes, checked the adapter in and out. No effect.

Does anyone know:
1. If it has to be a specific NVME card? My one is Samsung EVO 860, 250Gb.
2. If it's somehow related to the adapter problem? It thought the issue was only about the geometry and didn't affect functionality.

Cheers.


  Cannot power on the PBP
Posted by: MC68060 - 11-09-2019, 01:20 PM - Forum: General Discussion on Pinebook Pro - Replies (6)

Hi,

I just received my new Pinebook Pro today.
But I can not turn it on Sad

When I press the Power-Button most times nothings happens, sometimes the power-LED turns on for a quarter second and then it's off again.
I've tried with and without power-supply, read in the wiki about the emmc-switch and the SD-Card ribbon.
Tried both with no luck.

I tried also without battery and the power-brick cable connected, but also nothing.

Any suggestions?
