Shakti¶

Registry:: https://registry.platformio.org/platforms/platformio/shakti
Configuration:: platform = shakti

Shakti is an open-source initiative by the RISE group at IIT-Madras, which is not only building open source, production grade processors, but also associated components like interconnect fabrics, verification tools, storage controllers, peripheral IPs and SOC tools.

For more detailed information please visit vendor site.

Examples ¶

Examples are listed from Shakti development platform repository:

Debugging ¶

Debugging - “1-click” solution for debugging with a zero configuration.

Tools & Debug Probes ¶

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.
