OpenOCD and PicoTool (both documented in the Getting Started Guide) compiled and worked OK on Raspbian but did not compile under Fedora. There were two specific things I found that did not work on Fedora without modification.
Fedora tends to be on the leading edge and has more recent software development ‘ toolchain‘ packages. Actually, some of the pico tools do not compile correctly on Fedora without some modifications. Fedora is a lot different than Raspbian and some of the software dependencies needed for pico development and debugging are not documented. I happen to like and use the Fedora Linux distro (Fedora 34 at the time of this post). If you are developing in C/C++, I highly recommend the Pico Project Generator tool for creating new projects. Programmers have their choice of Python (using MicroPython or CircuitPython), C/C++ (using the SDK) or native assembler (using pioasm). There is a pico-setup script provided but it is only useful on Rasbian.
setting up a development environment) for the Raspberry Pi Pico on a Raspberry Pi is made easy by all the great documentation that is available from the Raspberry Pi Foundation.Īlthough, the documentation is designed specifically for using a Raspberry Pi and the Rasbian OS, you might find other similar Linux distros mentioned in the documentation (like Debian). It will be interesting to see how this chip is used in the future, especially in regards to the programmable I/O (PIO).Ĭoding (i.e.
The RP2040 was also made available to other microcontroller board manufacturers so we are now seeing boards from Adafruit, Arduino, Sparkfun and others. The PIO is something unique in the microcontroller world. The microcontroller chip (RP2040) used on the Pico was designed by the Raspberry Pi foundation and features a dual-core Arm Cortex-M0+ processor with 264KB internal RAM, support for up to 16MB of off-chip Flash and a wide range of flexible I/O options which includes I2C, SPI, and Programmable I/O (PIO).
