Pine64 PineNote Testing list

Nice to have

• Documentation and gui/tooling to set off-screens for the panel (tooling is there - needs polishing)
• Tooling to regenerate the u-boot logo partition with updated images

Functionality to be tested

• Factory image Check when flashed with Windows factory flashing tool!
• Can you enter maskrom with the pen
• Suspend:
  • Suspend-to-ram is working
  • Suspend-on-cover close/resume on cover-up works and is configurable
  • Travel mode can be activated and works
• Bluetooth:
  • Can be started and stopped (hciconfig hci0 up and hciconfig hci0 down, repeatedly)
  • BT Keyboard can be successfully paired and connected and used
  • BT Headphones can be used, uncluding volume keys
  • BT Microphone is usable
• [-] Working Pen Button (separate BLE-chip) (only batch-1)
• Working built-in audio
• USB:
  • usb-2 working
  • usb gadget mode (mtp, tablet)
  • usb mouse/keyboard is working
• xournalpp:
  • Writing in P-mode with waveform "BW+dithering" is smooth
  • Acceptable level of artifacts (in pure writing mode and in pdf-annotation mode)
• backlight:
  • warm backlight works
  • cold backlight works
• u-boot:
  • boot-into-maskrom with pen-magnet works
  • [ ]

Known issues

Bluetooth

• It seems any use of rfkill or hciconfig hci0 up/down will somehow break BT in the sense that transfer speeds drop dramatically, leading to consistent stuttering
• The combined BT+Wifi chip is the same one used in the Rpi3. Most reported issues also apply here: The BT and Wifi parts apparently share the same antenna, leading to significant cross-talk and interference, especially since the BT frequencies overlap with certain channels of the 2.5 GHz WIFI ranges. Moving to 5Ghz-Wifi will dramatically improve BT quality. Also, expect small stuttering during wifi scans or connections.

Things to implement/test

• [-] Simple gui for pen buttons/configurations (kernel stuff will be handled by the dbus service for non-root usage)
  • -> not required for batch 2
• How to boot into maskrom from linux
• Documentation/gui on how to configure Suspend-on-cover close/resume
• kexec (won't work on that before batch 2)
  • [-] kexec can be used to reboot into another kernel
  • [-] kdump works
