Hi, this is my initial work on getting NuttX to run on PicoCalc with Pico 2 on board
Currently: SD Card, SPI, I2C, PWM, Speakers, Serial connection are working.
Next: Display and builtin PicoCalc keyboard.
There is also firmware uf2 file in pre-release on github for pico 2 based PicoCalc

Also year ago NuttX landed on the moon Apache NuttX Powers World's Smallest Lunar Robot in Japan's Historic Autonomous Lunar Exploration Mission | Developer World
