CHIPS Alliance¶

Configuration:: platform = chipsalliance

The CHIPS Alliance develops high-quality, open source hardware designs relevant to silicon devices and FPGAs.

For more detailed information please visit vendor site.

Examples ¶

Examples are listed from CHIPS Alliance development platform repository:

Debugging ¶

Debugging - “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.
