The PineNote

The PineNote is the first hybrid notepad computer device combination of notebook, tablet and e-reader using an e-ink panel. It is derived from the Quartz64 Model-A single-board computer and powered by Rockchip RK3566 quad-core ARM Cortex-A55 64-bit SoC with Mali G52 GPU.

Introduction

State of the software

Warning: The version of Debian-based Linux distribution shipped with the second PineNote batch contains a U-Boot build that prevents suspend-to-RAM from working correctly and make entering MaskROM mode using a magnet not possible. This was caused by the unfortunate timing, so the factory ended up installing version of the operating system image that contained these issues. The required fixes are already available in the shipped Linux distribution, but they need to be installed manually by the users.

The PineNote is based on the Rockchip RK3566 SoC, which was released in 2021. The upstreaming status of the SoC functionality can be found on the Quartz64 development wiki page of the Quartz64 single-board computer that uses the same SoC. In the PineNote development wiki page you'll find the items specific to the PineNote.

The early adopter's batch of the PineNote is aimed solely at early adopters - more specifically, the units are solely intended to find their way into the hands of users with extensive Linux experience. If you’re looking to buy a PineNote in the first batch, you must expect to write software for it, not to write notes on it. The software shipping from the factory for the first batch will not be suitable for taking notes, reading e-books, or writing your dissertation. It may not even boot to a graphical environment.

In October 2024, the second PineNote batch was announced. This batch started shipping during the first half of November 2024 with a Debian-based operating system, currently developed here: [1]. Please note, however, that this batch is still aimed at developers with Linux and embedded experience, and should not be expected to meet general-user readiness.

Help and support

Still have any questions regarding software, shipping, or ordering after reading this wiki? Please don't hesitate to contact the community in the bridged community channels for detailed answers or simply to chat with friendly people in the community! See Main Page#Community and Support.

Please keep in mind that PINE64 is not like a regular company (see the PINE64 philosophy) and that support resources are limited - the best way to get support quickly is to ask in the community chat! Please only contact the PINE64 support directly if questions couldn't be solved via the community chat or this wiki.

Software releases

While there are no robust and tested operating system releases for the PineNote available at this time, various linux distributions can be installed on the PineNote, with various degrees of working functionality. Operating system software releases, or efforts to create them, can be found in the PineNote Software Releases section. Please join the development effort and help creating one.

Hardware

This section includes discussions and their results regarding hardware changes and debugging of the PineNote.

Resolved issues

The following topics have resolved:

  • PineNote/Hardware Changes/Closed Case UART
  • Could the USB-C port support USB 3.1 5Gbps? Yes and no. The RK3566 only has a host-mode 5Gbps controller, meaning it can only negotiate such a high data rate with a device such as a flash drive. When the RK3566 is acting as a device, it only supports 480Mbps transfer rates. The hardware required to switch between these modes would raise the PineNote's price unreasonably. Therefore, the USB-C port will remain at USB 2.0 speeds for Host and Device mode.
  • Could the USB-C port output DisplayPort? Yes and no. The hardware required to support such a feature would raise the PineNote's price unreasonably. Therefore, DisplayPort output will not be possible through the USB-C port.
  • Where is the microSD card slot? The case design of the PineNote is fixed, making physical changes like adding a microSD card slot would raise the cost unreasonably.
  • How will I install software to the PineNote? This is a hardware and software question. If the software on your PineNote is completely broken and cannot boot to a recoverable state, a Hall (magnet) sensor was fitted to the PineTab motherboard as U9009. This sensor is attached to SARADC_VIN0_KEY/RECOVERY on the RK3566. With the device powered off, and screen face down, holding a magnet over U9009 and plugging in a USB-C cable causes the device to boot into "rockusb" flash mode. With proper flashing software and drivers, it should be possible to load a new operating system using rockusb if the system is soft-bricked. Of course, software vendors will need to be more careful with flashing firmware and providing useful "recovery" options on this device due to this process's relative difficulty to other PINE64 devices.
  • PineNote/Battery Replacement

Unresolved issues

The following concerns have been brought up as open, unanswered topics:

  • Does Audio Adapter Accessory Mode work? It appears that the Headphone output of the audio codec was routed to the USB-C audio+USB switch, but it's unclear whether CC lines are hooked up correctly for detection of such a device. The PineNote hardware team will be testing this functionality soon (as of August 19, 2021). Note that Audio Accessory mode is detectable by reading the I2C registers of the WUSB3801Q. So connecting ASEL to a GPIO would be enough to get this working if it is not working already.
  • Why is the Headphone output of the audio codec routed to the speakers? HPL_OUT is routed from the RK817 PMIC and audio codec to U9010 (the USB-C switch) and U6 (the audio amplifier). SPK_OUT is unused. It seems like SPK_OUT should be routed to U6 and HPL_OUT to U9010.
  • Nitpick: The cold white charging LED bleeds through the gap between the rear case and the device's face. It does not bleed onto the screen, but it is jarring in low-light conditions or when the screen is amber. Could be resolved in software by turning off the charge LED when the screen is on.
  • Is there any way to indicate when the device is in rockusb mode, such as connecting a certain magic pin to the power LED?
  • The modem/4G connector (J6010) has its I2C and UART pins unconnected. Could those be connected to the SoC?

UART Dongle

See main article: PineNote Development/UART
Warning: The second PineNote batch, which started shipping during the first half of November 2024, is the last batch that has the USB UART dongle included in the box.

The USB UART dongle delivered with the PineNote allows you to have access to a serial port via USB-C Debug Accessory Mode (DAM) without having to open up the device. The factory-installed firmware runs at a baud rate of 1,500,000 bps, 8 data bits and 1 stop bit, no parity, and no flow control. The USB-C male end should go into the PineNote and the female end can be connected with a standard USB-C cable to your computer.

It is relatively easy to build your own UART interface with a USB-C breakout board (for example https://www.ebay.com/itm/275407037613), two resistors and a 3.3V USB serial adapter. It is basically just two 1K pull up resistors (R3, R4), the data sheet values of 10K isn't whats on the real hardware, see the schematic. The pull ups enable the serial output on SBU1 and SBU2 you can use with any 3.3V USB serial adapter.

The UART dongle is not necessary to flash the PineNote, but is essential if something goes wrong to fix it without having to open the case.
