If everything goes well you should have a UF2 file in build/fuzix.uf2 and a filesystem.img image file in your current working directory. So for instance if you’re building things on a Raspberry Pi and you’ve run the pico_setup.sh script, or followed the instructions in our Getting Started guide, you’d point the PICO_SDK_PATH to export PICO_SDK_PATH = /home/pi/pico/pico-sdkĪfter that you can go ahead and build both the FUZIX UF2 file and the root filesystem. Then change directory to the platform port $ cd Kernel/platform-rpipico/Īnd edit the first line of the Makefile to set the path to your pico-sdk.

If you don’t already have the Raspberry Pi Pico toolchain set up and working you should go ahead and set up the C/C++ SDK.Īfterwards you need grab the the Pico port from GitHub. While there is a binary image available, it’s easy enough to build from source. Building FUZIX from sourceįUZIX is a “proper” Unix with a serial console on Pico’s UART0 and SD card support, using the card both for the filesystem and for swap space. So you can now run Unix on a $4 microcontroller.

Earlier in the week David Given - who wrote both the MSP430 and ESP8266 ports - went ahead and ported it to Raspberry Pi Pico and RP2040. Since then FUZIX has been ported to other architectures such as 6502, 68000, and the MSP430.
