The PineTab-V with the detachable keyboard attached

The PineTab-V is PINE64's first RISC-V tablet. It is based on the JH7110 64-bit RISC-V SoC. The packaging is very similar to ARM-based PineTab2.

Introduction

In late 2022, PINE64 announced plans to help grow the RISC-V hardware ecosystem alongside the existing ARM-based device line-up. The PineTab-V is an experimental device, which ships without an OS and without any promises. The JH7110 RISC-V SoC, and the RISC-V architecture in more general, is currently best described as having limited Linux support. You can think of it as a convenient development platform targeted at those of you interested in bringing Linux support to JH7110 and, by extension, the entire RISC-V ecosystem.

Software

State of the software

Connecting the UART adapter

UART Adapter

The UART serves as a console for early boot and kernel messages, and also offers access to a root shell in the factory test image. The UART adapter allows access to the UART through the USB 2.0 Type-C port:

  • Insert the UART adapter face-up in the USB 2.0 Type-C port (the USB port furthest from the power button).
  • Connect a USB cable from another computer to the port on the adapter marked "DEBUG". The green LED on the adapter should light up. The other adapter port can be connected to USB power if you don't want to run the tablet on its battery.
  • In a terminal window on the other computer, use tio, screen, minicom, or another application that supports serial port communication to connect via USB serial at 115200 bit/s 8N1 (8 data bits, no parity, 1 stop bit):
    tio /dev/ttyUSB0
    screen /dev/ttyUSB0 115200
    minicom -D /dev/ttyUSB0 -b 115200
    • Install one of the above from your distribution's package manager if none are already installed.
    • The device may have a different name, particularly if multiple USB serial devices are connected. On macOS it will have a name like /dev/tty.usbserial-nnnn.
    • If Permission denied is reported, you may need to be added to the group that can access the port with a command like sudo usermod -a -G dialout $USER. Then log out and log back in or use a command like newgrp dialout to create a new shell in that group.
    • Ubuntu-based distro users may encounter the error, "cannot open /dev/ttyUSB0: No such file or directory". If this occurs, check the output of sudo dmesg --follow and unplug/replug the USB to look for any errors. If you see an error like, "usb 1-1: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1", then the brltty service is likely conflicting with this device. Brltty provides access to blind users who use a braille display; if you do not need this service, try disabling it using these commands:
      sudo systemctl stop brltty-udev.service
      sudo systemctl mask brltty-udev.service
      sudo systemctl stop brltty.service
      sudo systemctl mask brltty.service

The switch on the UART adapter has no function on the PineTab-V; the boot order is controlled by the Vol-/Vol+ switches.

Frequently asked questions

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.
