PineTab2

The PineTab2 with the detachable keyboard attached

The PineTab2 is PINE64's successor to the original PineTab Linux tablet computer, featuring a faster processor and better availability. The tablet is available in two configurations, 4GB of RAM and 64GB of internal storage or 8GB of RAM and 128GB of internal storage. The tablet ships with a detachable keyboard that doubles as a protective cover.

The tablet is designed around the Rockchip RK3566 processor, which features 4 energy-efficient Cortex-A55 64-bit ARM cores and enjoys good mainline Linux support. Similarly packaged RISC-V tablet is PineTab-V.

Pre-orders started on the 13th of April 2023, with pricing starting at USD 159 for the 4GB/64GB version and USD 209 for the 8GB/128GB version. The PineTab2 began shipping on June 2, 2023.

Getting started

The PineTab2 can be started by pressing and holding the power button for two seconds. The device is initialized at the first boot and will power-cycle while the partition table is populated.

Note: If the initialization process is interrupted it might lead to a corrupted operating system installation. In that case reinstall the operating system as explained below.

The PineTab2 ships with DanctNix Arch Linux and comes with a pre-set user and the default password 123456.

Default credentials
Default user	123456

You can create a new user and set your own password after the initial boot. To do so, go to system settings -> users and create a new profile using your preferred name and password.

Software

All operating systems for the PineTab2 are delivered by community developers and partner projects. Aside from the operating system that comes pre-installed on your device, you can install and run any other operating system available for the PineTab2. Most, if not all operating systems for the PineTab2 are open and free, such as Linux and BSD.

Releases

The PineTab2 ships with Danctnix Arch Linux. The factory image can be found here:

• https://echo.danctnix.org:7269/danctnix-factory-image-20230527.img.xz (1.5 GB)

There are currently no further releases. Future releases for the PineTab2 will be listed under PineTab2 Releases. Your contributions are wanted!

Installation instructions

The PineTab2 is capable of running different operating systems from the internal flash memory (eMMC) and from microSD card.

Preparing the microSD card

To write an operating system to the microSD card (typically called "flashing" in the community), you need to first download a compatible image from the releases section.

Next you need to decompress the downloaded image. The images are typically compressed in an archive format such as xz to reduce the download size. If you are using a graphical tool such as balenaEtcher or Gnome Disks it will handle the decompression of the image in the flashing step automatically.

Further you need to flash the image to the microSD card. This can be done using various tools, for example balenaEtcher (recommended for new users), Gnome Disks or command-line tools such as cp and dd. Insert the microSD card in a microSD card reader connected to your computer and then choose a tool of your liking.

Graphical applications:

• balenaEtcher (Microsoft Windows, macOS, Linux): Click on Flash from file and select the image. Then select the microSD card target device and click on Flash!.

• Gnome Disks (Linux): Select the microSD card target device on the left side in the Disks list. Then select the three dot menu on the top right and click on Restore Disk Image.... Select the image, verify the correct device is selected and then click on Start Restoring....

Command-line tools:

• cp: sudo cp IMAGE.img /dev/[DEVICE]

• dd: sudo dd if=IMAGE.img of=/dev/[DEVICE] bs=1M status=progress conv=fsync

Note: Make sure to replace IMAGE.img and [DEVICE] with the filename of the image (double check if it is decompressed and has the file extension .img) and the device name. You can use the command lsblk to find the device name. Make sure to flash to the whole device instead of partition 1 and that you're NOT selecting /dev/sda1 or /dev/mmcblk0p1 as target. Be very careful to select the correct device, as the tools can overwrite your data when the wrong device is selected.

Then insert the microSD card into the PineTab2 and boot the device. It should now boot the new operating system from the microSD card.

Keyboard

When connecting the keyboard to the Pinetab2 ensure that the camera and the golden pogo pin connectors are correctly aligned.

Change the backlight with Pinekey - Ctrl-Right.

Development efforts

Main Article: Quartz64 Development

Linux mainline is already quite far along for the device, as the SoC is the same as is used in the Quartz64 line of devices. Check the main article for the big picture; PineTab2 specific issues are listed here.

Known Issues

• The display panel driver is in PineTab2's kernel fork, and needs to be submitted to upstream.
• The BES2600 Wi-Fi driver needs porting/major cleanup. This is a priority, but for now, you can USB tether a phone or use a supported WI-FI dongle.
• The BES2600 Bluetooth driver needs to be implemented.
• The Camera driver needs to be written.
• Suspend does not currently work due to a driver issue. Suspend is disabled in the factory image for your protection. Caveat Emptor if you chose to unmask the feature prior to it being fixed.

Frequently Asked Questions

Does the Tablet support a Pen?

No, adding a digitiser for pen inputs would make the price too high.

Can I run Android on it?

Theoretically yes, practically there's little chance anyone wants to make a well-supported Android build for this device. If you're looking for an Android tablet, buy any mainstream tablet, you'll get better value for your money.

Is there SPI Flash?

Unclear. The schematic shows a 128Mbit SPI flash chip, but it's possible that production models won't have it populated. Update this section once we've determined this.

My only Development Experience is Visual Basic Macros in Excel and Redstone in Minecraft, should I buy this?

At this stage, probably not, unless you're happy with a tablet that has a buggy Wi-Fi driver and no camera controller driver.

How does the Tablet compare to a Pinebook Pro?

It's slower, as it is intended to be a successor to the PineTab1, not the Pinebook Pro. It'll still handle web browsing, video playback and documents fine though.

What is the Performance of the PineTab2 compared to the PineTab-V?

The PineTab2 is notably faster than the PineTab-V. You can see this by comparing the Quartz64 sbc-bench results to the Star64 ones. Performance should not be a factor of consideration when purchasing a PineTab-V.

Does PineTab2 play back DRM'd Content such as Netflix?

No, there are no Widevine binaries included in the image the PineTab2 ships with. They need to be taken from ChromeOS and probably patched https://gist.github.com/DavidBuchanan314/c6b97add51b97e4c3ee95dc890f9e3c8

How-to

Putting the Device into Maskrom Mode

To recover from a bad eMMC/SPI flash, it seems you can make the bootrom enter the USB recovery mode by applying a low(?) signal to the SSTX1_P or SSTX2_P pin of the USB2-only Type-C connector (the one that does UART.)

Networking using USB

Until the internal BES2600 WIFI has a stable driver, the community suggests that you connect using USB. This section summarizes the more detailed information in File:PineTab2 USB Guide.pdf, which covers connecting via a tethered Android phone, a suitable USB WIFI adapter, a wired USB Ethernet adapter, and a tethered iOS device.

Selecting a USB WIFI Adapter

Insert a supported WIFI dongle in the upper USB port, using a USB-C to USB-A adapter as necessary. As a general rule, single state adapters are recommended. Even better, select one from this list: https://github.com/morrownr/USB-WiFi/blob/main/home/The_Short_List.md

If you must use a multi-state adapter and it isn't recognized by the kernel, you can try ejecting the device. This should force it back into adapter mode. If this does not work, you can try installing usb_modeswitch to troubleshoot. You will need to temporarily use another method to get internet (such as phone tethering below) or load the package on an SD card to install it.

Performing USB Tethering with an Android Phone

This guide simply describes HOW to undertake this option. The user is responsible for ensuring that their wireless plan permits such use, and for any fees incurred.

You can use an Android phone as a network adapter.

You'll need:

• An Android phone
• A USB OTG adapter (USB-C to USB-C may work, not tested)
• Some knowledge of your variation of Android

Do the following in order:

• Plug in the device to the PineTab2 using the USB cable and a USB OTG adapter
• On your android phone, open the settings app (specifics from here may vary on version)
  • Navigate to "Network & Internet"
  • Navigate to "Hotspot & Tethering"
  • Tap on "USB Tethering"

You should now see a new network interface on the PineTab2.
