KotoOS v0.2 expands the original RP2040 PicoCalc platform with a hardware-validated RP2350A / Pico 2 W target while preserving compatibility with the RP2040 profile.

What's included

  • kotoos-firmware-rp2040-v0.2.0.uf2 — product firmware for Raspberry Pi Pico / RP2040 PicoCalc modules
  • kotoos-firmware-rp2350a-v0.2.0.uf2 — product firmware for Raspberry Pi Pico 2 W / RP2350A PicoCalc modules
  • kotoos-sdcard-v0.2.0.zip — common FAT32 SD card contents with 19 self-contained KPA apps and the CC0 SKK dictionary
  • SHA256SUMS.txt — SHA-256 checksums for the firmware and SD card archive

Install

  1. Format an SD card as FAT32 and copy the contents of kotoos-sdcard-v0.2.0.zip to its root.
  2. Hold BOOTSEL on the Pico or Pico 2 W and copy the matching UF2 onto the mounted drive.
  3. Insert the SD card and power on; KotoOS boots into the launcher.

Use only the UF2 matching the controller installed in the PicoCalc.

Highlights

  • Hardware-validated RP2350A / Pico 2 W support alongside RP2040
  • KotoIDE VS Code extension foundation, app project workflow, and live simulator reload
  • Retained tilemaps and streamed full-color KIM1 image galleries
  • SLD4 background audio streaming with cooperative SD I/O
  • Hardened SD SPI startup with 400 kHz acquisition retries and 25 MHz transfers
