SiFive¶

Configuration:: platform = sifive

SiFive brings the power of open source and software automation to the semiconductor industry, making it possible to develop new hardware faster and more affordably than ever before.

For more detailed information please visit vendor site.

Examples ¶

Examples are listed from SiFive development platform repository:

Debugging ¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.

On-Board Debug Tools ¶

Boards listed below have on-board debug probe and ARE READY for debugging! You do not need to use/buy external debug probe.
