![]() ![]() Now plug the card into a USB card reader and then into your Raspberry Pi or laptop computer. I was using a 4GB card, as that was the smallest I could find, but it’s not that important. As the partitions we’re going to put onto it are only going to take up 34MB it doesn’t really matter what size you’ve got to hand. Command line missing coolterm windows#Comparable tools are available on both MS Windows and Apple macOS, but the exact details will differ. The following instructions are for building your file system on a Raspberry Pi, or another similar Linux platform. We’re going to have to get our hands a bit dirtier than that. Unlike the Raspberry Pi OS images you might be used to, you can’t just use something like Raspberry Pi Imager to write it to an SD card. The filesystem.img image file we built earlier isn’t a bootable image. Unfortunately, it won’t be much use without a filesystem. The volume will automatically unmount, and your Pico is now running Unix. Double-click to open it, and then drag and drop the UF2 file into it. Then release the button after the board is plugged in.Ī disk volume called RPI-RP2 should pop up on your desktop. Plug the cable into your Raspberry Pi or laptop, then press and hold the BOOTSEL button on your Pico while you plug the other end of the micro USB cable into the board. Go grab your Raspberry Pi Pico board and a micro USB cable. You can now load the UF2 file onto your Pico in the normal way. 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. Command line missing coolterm serial#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. ![]()
