Introducing PineBook Pro

Pinebook Pro running stock Debian with MATE

The Pinebook Pro is a Linux and *BSD ARM laptop from PINE64

It is built to be a compelling alternative to mid-ranged Chromebooks that people convert into Linux laptops. It features an IPS 1080p 14″ LCD panel, a premium magnesium alloy shell, high capacity eMMC storage, a 10,000 mAh capacity battery, and the modularity that only an open source project can deliver.

Key features include: the RK3399 SOC; USB-C for data, video-out and power-in (3A 5V); privacy switches for the microphone, BT/WiFi module, and camera; and expandable storage via NVMe (PCIe 4x) with an optional adapter.

The Pinebook Pro is equipped with 4GB LPDDR4 system memory, high capacity eMMC flash storage, and 128Mb SPI boot Flash. The I/O includes: 1x micro SD card reader (bootable), 1x USB 2.0, 1x USB 3.0, 1x USB type C Host with DP 1.2 and power-in, PCIe 4x for an NVMe SSD drive (requires an optional adapter), and UART (via the headphone jack by setting an internal switch).

The keyboard and trackpad both use the USB 2.0 protocol. The LCD panel uses eDP MiPi display protocol.

Many different Operating Systems (OS) are freely available from the open source community and partner projects. These include various flavors of Linux (Ubuntu, Debian, Manjaro, etc.) and *BSD.


Software and OS Image Downloads

Pinebook Pro

Under 'Pinebook Pro Software and OS Image Download Section' you will find a complete list of currently supported Operating System images that work with the Pinebook as well as other related software.

The list includes OS images and descriptions of:

Quick Links to OS Images Build Sources

Some of the provided OS images are still in beta or nightly build and only fit for testing purposes. These images ought to be avoided for normal usage - use them at your own risk

Keyboard

The Pinebook Pro is available in two keyboard configurations: ISO and ANSI. Both the keyboard and trackpad in the Pinebook Pro use the USB 2.0 protocol and show up as such in xinput. The keyboard features function (Fn) keys in the F-key row, which include display brightness controls, sound volume, trackpad lock, and other functionality. There is also a custom PINE64 logo key that functions as Menu/Super key. It has also a secondary functionality for setting the privacy switches.

The keyboard firmware binary can be flashed from userspace using the provided open source utility.

Documentation for the keyboard can be found in Datasheets for Components and Peripherals.

Typing special characters

The UK ISO Layout does not have dedicated keys for characters like the German umlauts (Ä,Ö,Ü, etc). Certain characters can still be generated by means of either key combinations or key sequences.

Character Key combination/sequence
Ä, Ö, Ü, ä, ö, ü [AltGr]+["] followed by [A], [O], [U], [a], [o] or [u]
µ [AltGr]+[m]
Ø, ø [AltGr]+[O], [AltGr]+[o]
@ [AltGr]+[q] (as on the German layout)
ß [AltGr]+[s]
§ [AltGr]+[S]
° [AltGr]+[)]

Privacy Switches

There are three privacy switches mapped to the F10, F11 and F12 keys on the Pinebook Pro keyboard. They de/activate the following:

Privacy switch function and description
Combination Effect Description
PINE64 logo key+F10 Microphone Privacy switch CAPs lock LED blinks. 2 blinks = enabled, 3 blinks = disabled
PINE64 logo key+F11 WiFi Privacy switch NUM lock LED blinks. 2 blinks = enabled, 3 blinks = disabled. Re-enabling requires reboot (or a command line hack to bind/unbind).
PINE64 logo key+F12 Camera privacy switch CAPs lock and NUM lock LEDs blink together. 2 blinks = enabled, 3 blinks = disabled

(Press the PINE64 logo key plus Fn (10/11/12) for 3 seconds)

The keyboard uses special firmware that operates separately of the operating system. It detects if either the F10, F11 or F12 key, and the Pine key were pressed for 3 seconds. This disables the peripherals as listed above by cutting off their power. Which has the same result as cutting off the power to each peripheral with a physical switch. This implementation is very secure since the firmware that determines whether a peripheral gets power is not a part of the Pinebook Pro’s operating system. So the power state value for each peripheral cannot be overridden or accessed from the operating system. The power state setting for each peripheral is stored across reboots.

Trackpad

The trackpad is large, smooth (metallic to-the-touch), and has two actuating buttons. It is the only component of the Pinebook Pro held in place with strong adhesive tape. It supports multi-touch functionality. Documentation for the trackpad can be found in Datasheets for Components and Peripherals. The trackpad firmware binary can be flashed from userspace using the provided open source utility (https://github.com/ayufan-rock64/pinebook-pro-keyboard-updater).

Everyone with a Pinebook Pro produced in 2019 should update their keyboard and trackpad firmware.

Brief description of trackpad flashing process (please refer to original documentation for details)

Before you start: Your Pinebook Pro should be either fully charged or, preferably, running of mains. This utility will be writing chips on the keyboard and trackpad, so a loss of power during any stage of the update can result in irrecoverable damage to your trackpad or keyboard.

The scripts ought to work on all OSs available for the Pinebook Pro. Some OSs may, however, require installation of relevant dependencies.

What you'll need:

  • Your Pinebook Pro fully charged / running off of mains power
  • Connection to WiFi
  • An external USB keyboard/ access to the Pinebebook Pro via ssh

What you need to do: 

git clone https://github.com/ayufan-rock64/pinebook-pro-keyboard-updater
cd pinebook-pro-keyboard-updater
sudo apt-get install build-essential libusb-1.0-0-dev xxd
make

Step 1 

cd pinebook-pro-keyboard-updater
sudo ./updater step-1
sudo reboot

Step 2 (after reboot) 

cd pinebook-pro-keyboard-updater
sudo ./updater step-2
sudo reboot

Power Supply

  • Input Power: 5V DC @ 3A
  • Mechanical: 3.5mm OD / 1.35mm ID, Barrel jack
  • USB-C 15W PD quickcharge
  • Only use one power input at a time, barrel jack OR USB-C

LEDs

In total there are four LEDs on the Pinebook Pro, three of which are placed in the top left side of the keyboard, and one near the barrel-port:

1. The red LED next to the barrel-port indicates charging. It will illuminate when mains power is supplied to the Pinebook Pro from either the standard power supply unit or a USB-C smartphone charger.
2. The power indicator LED on the Pinebook Pro supports three different colours: green, amber and red. It is also capable of flashing/blinking to indicate activity. In the default Debian with MATE build, green LED means power and red means suspend (amber is unused).
3. The Num lock, green LED.
4. The Caps lock, green LED.

(The Num and Caps lock LEDs have a secondary function. When the privacy switches get activated they blink to confirm that switch has been activated.)

Using the UART

Headphone Jack UART wiring reference

UART output is enabled by flipping the UART switch to the ON position (item 9). To do so you need to remove the Pinebook Pro's bottom cover - please follow proper disassembly and reassembly protocol. The OFF position is towards the touchpad, the ON position is towards the display hinges.

With the UART switch in the ON position, console is relayed via the audiojack and the laptop's sound is turned OFF. PINE64 store sells a dedicated serial console but you can make your own if you have a serial console USB 2.0 adapter and old/ broken headphones. If you do make your own cable, please ensure that you are using a 3.3v interface (such as the CH340, FTDI-232R or PL2303 - which are often sold in 3.3v and 5v variants) to avoid damage to the CPU.

Insert the USB plug of the cable into an open USB port on the machine which will monitor. Run the following in a terminal:

$ lsusb

you should find a line similar to this:

Bus 001 Device 058: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter

You may have to clean the USB contacts of the Serial cable to get a good connection if you do not find that line.

The audio jack of the Serial cable should be fully inserted into the Pinebook Pro audio port.

Serial output should now be accessible using screen, picocom or minicom (and others). Examples:

screen /dev/ttyUSB0 1500000

picocom /dev/ttyUSB0 -b 1500000

minicom -D /dev/ttyUSB0 -b 1500000

Current versions of U-Boot do not use the UART for console output. The console function is activated by the Linux kernel. Thus, if you use a non-Pinebook Pro Linux distro and want the UART as a console, you have to manually enable it.

Using the optional NVMe adapter

The optional NVMe adapter allows the use of M.2 cards that support the NVMe standard, (but not SATA standard).

Installing the adapter

The v2.1 SSD adapter that is shipped with the initial Pinebook Pro batches has a couple of problems although with a little hacking they can still be used. There is an unofficial tutorial on the forums describing the mods.

Using as data drive

As long as the kernel in use has both the PCIe and NVMe drivers, you should be able to use a NVMe drive as a data drive. Even automounting at boot, (from eMMC or SD card). This applies to both Linux and FreeBSD, though Android or Chromium OS may need testing. Simply use the normal partitioning and file system creation tools.

Using as OS root drive

It is not possible to boot directly off a NVMe drive. The SoC does not include the NVMe boot code, thus the NVMe is not in the SoC's boot order.

Howevever, it is possible to initially boot off an eMMC or SD card, then transfer to a root file system on the NVMe. Even have all the other file systems on the NVMe. except /boot.
Instructions for doing this are not complete as of 2019/11/20, but the forums has had people doing this with successful results.

Another user has described in the forums a modified version of U-Boot with NVMe drivers, that uses /boot and / off the NVMe drive.
The U-Boot code does still has to exist on an eMMC or SD card.

Caring for the PineBook Pro

Bypass Cables

The mainboard features two (disconnected by default) bypass cables that are only to be used with the battery disconnected. The female (10) male (6) ends of the bypass cables can be connected to provide power to the mainboard if you need to run the laptop without a battery. Please refer to this engineering notice.

WARNING: Do not connect the bypass cables with the battery connected. Using the bypass cables with the battery connected can permanently damage the computer.

Troubleshooting guide

Tips, tricks and other information for troubleshooting your Pinebook Pro

New from the factory - Pinebook Pro won't boot / power on

  • Some Pinebook Pros came from the factory with the eMMC switch in the disabled position. It should be switched towards the back / hinge to enable the eMMC.
  • The eMMC may have come loose during shipment. Open the back and verify that the eMMC is firmly seated.
  • You may want to try unplugging the SD card daughterboard ribbon cable and see if it powers on (remove the battery and peel off a bit of the tape before unplugging it to avoid damage). If it does, try reseating it on both sides. It might have come loose during shipping.
  • It's possible that your eMMC is empty from the factory. Simply create a bootable SD card and see if your Pinebook Pro boots. If so, you can then write an OS image to the eMMC.

Pinebook Pro won't boot when using UART console cable

  • If you're using the UART cable sold on the Pine Store, you may want to see if it boots after you disconnect it. Some users report that custom-made cables based on FTDI UART adapters do not cause this issue.

Pinebook Pro will not power on after toggling the eMMC enable/disable switch

  • This may happen if you meant to toggle the UART/Headphone switch (9) towards touchpad for headphone use and instead you toggled the eMMC enable/disable switch (24).
  • After reenabling eMMC by toggling switch (24) towards hinge, if Pinebook Pro does not turn on then press the RESET button (28). It is clearly marked 'reset' on the PCB board.

Keys not registering / missing keys when typing

This issue occurs when your thumb or edge of the palm makes contact with left or right tip of the trackpad when you type. This is due to the palm rejection firmware being too forceful. Instead of only disabling the trackpad, so your cursor does not move all over the screen, it disables both the trackpad and the keyboard.

Using Fn+F7 to disable the touchpad will keep it from also disabling the keyboard.

A firmware update has been released to address this.

WiFi issues

  • First, check the privacy switches to make sure your WiFi is enabled. They are persistant. See Pinebook_Pro_Main_Page#Privacy_Switches
  • Next, you may have to modify the file "/etc/NetworkManager/NetworkManager.conf" as user "root", and replace "managed=false" with "managed=true". Then reboot.
  • For connections that drop and resume too often, it maybe WiFi power management from earlier OS releases. Later OS releases either removed WiFi power management, or default to full power. Try an updated OS.
  • When using an alternate OS, WiFi is un-usable or crashes alot. This may be due to the WiFi firmware in this alternate OS, is not appropriate for the WiFi chip in the Pinebook Pro.

Sound issues

  • If you never get sound from the headphone jack, but do when you select speakers, the headphone / UART console switch may be set to the UART mode. You can open the back and check the switch's status. If set to UART mode, switch it to headphone mode. See parts layout for location and position of switch for each function.
  • Others report that certain OSes have no sound at all. Try another OS via SD card and see if you can get sound that way, to eliminate hardware problems.
  • When using the USB C alternate DisplayPort mode, it's possible that the audio has been re-directed through this path. If your monitor has speakers, you may see if they work. Otherwise, the fix is unknown at present.

Accessing the Internals - Disassembly and Reassembly

Pinebook Screw stand-offs correct placement and location


WARNING: Do not open the laptop by lifting the lid while the Pinebook Pro bottom cover is removed - this can cause structural damage to the hinges and/or other plastic components of the chassis such as the IO port cut-outs.

WARNING: When removing the back cover plate, use care if sliding fingertips between back cover plate and palm rest assembly. The back cover plate edges are sharp.

When disassembling the laptop make sure that it is powered off and folded closed. To remove the bottom cover of the Pinebook Pro, first remove the ten (10) Phillips head screws that hold the bottom section of the laptop in place. Remove the cover from the back where the hinges are situated by lifting it up and away from the rest of the chassis.

During reassembly, make sure that the back-screw standoffs are in place and seated correctly. To reassemble the Pinebook Pro, slide the bottom section into place so it meets the front lip of the keyboard section. Secure the front section (where the trackpad is located) in place using the short screws in the front left and right corners. Then proceed to pop in the bottom panel into place. Secure the bottom section (where hinges are located) by screwing in the left and right corners. Then screw in the remaining screws and run your finger though the rim on the chassis to make sure its fitted correctly. Note that the front uses the remaining 2 short screws.

NOTE: The screws are small and should only be finger tight. Too much force will strip the threads. If after installing screws the back cover plate has not seated properly on one side, open the display and hold the base on either side of the keyboard and gently flex the base with both hands in opposing directions. Once the side pops further in, then recheck the screws on that side. If it does not pop back in, just let it be.

Mainboard Switches and Buttons

There are two switches on the main board: disabling the eMMC (24), and enabling UART (9) via headphone jack.

The Reset and Recovery buttons (28): the reset button performs an immediate reset of the laptop. The Recovery button is used to place the device in maskrom mode; this mode allows flashing eMMC using Rockchip tools (e.g. rkflashtools).

Bootable Storage

The Pinebook Pro is capable of booting from eMMC, USB 2.0, USB 3.0, or an SD card. It cannot boot from USB-C. The boot order of the hard-coded ROM of its RK3399 SoC is: SPI NOR, eMMC, SD, USB OTG.

At this time, the Pinebook Pro ships with a Debian + MATE build with uboot on the eMMC. Its boot order is: SD, then eMMC. Booting off USB storage is not currently available, but will be in the future.

(An update has been pushed for the default Debian + MATE build that improves compatibility with booting other OSs from an SD card. In order to update, fully charge the battery, establish an internet connection, click the update icon in the toolbar, and then reboot your Pinebook Pro. Please see this log for details.)

Please note that PCIe, the interface used for NVMe SSD on the Pinebook Pro, is not bootable on the RK3399 and therefore is not a part of the boot hierarchy. It is possible to run the desired OS from NVMe by pointing extlinux on the eMMC to rootfs on the SSD. This requires uboot, the Kernel image, DTB, and extlinux.conf in a /boot partition on the eMMC.

eMMC information

The eMMC storage will show up as multiple block devices:

  • mmcblk1boot0 - eMMC standard boot0 partition, may be 4MB
  • mmcblk1boot1 - eMMC standard boot1 partition, may be 4MB
  • mmcblk1rpmb - eMMC standard secure data partition, may be 16MB
  • mmcblk1 - This block contains the user areas

Only the last is usable as regular storage device in the Pinebook Pro. The device number of "1" shown above may vary, depending on kernel.

Boot sequence details

The RK3399's mask 32KB ROM boot code looks for the next stage of code at byte off-set 32768, (sector 64 if using 512 byte sectors). This is where U-Boot code would reside on any media that is bootable.
