Before you start

  • Back up your stock system card. A full image of it is the only way back to stock.
  • You need a spruceOS nightly from after 2026-09-19 (newer than v4.4.2-20260919) on a second card, formatted FAT32 (exFAT won't mount). Older spruceOS builds boot, but touch, sleep and brightness won't work right.

Install

The spruce installer has beta support for oakMOSS.

To install manually:

  1. Write the image to the system card with Raspberry Pi Imager or a similar tool (in Imager: "Use custom", then pick the .img.xz). Leave verification on.
  2. Once the card is ejected, put it straight into the device. On Windows, don't plug it back into the PC first: Windows can rewrite the card's partition table so it no longer boots. If that happens, write it again.
  3. The system card goes in the slot your stock system card came from, and the spruceOS card in the other slot.
  4. Power on.

What's new

  • XU20 V32 support.
  • Touch on the XU20 and Zero 40.
  • Fixed: the XU20 and Zero 40 sometimes stuck at the boot logo.
  • Fixed: rebooting from spruce powered the device off.
  • The Zero 40 keeps the same WiFi address, and so the same IP, across reboots.
  • New oakMOSS boot logo. On the XU20 and Zero 40, bootloader warnings and the low-battery screen now show instead of looking like a freeze.

Known limitations

  • Sleep turns the screen off and pauses the game. Full suspend isn't supported on these devices.
  • Beta: tested on one unit of each device.

Checksums

sha256sum -c SHA256SUMS checks the downloads. Each *-BUILD-INFO.txt lists exactly what went into its image.
