platform = riscv
RISC-V is an open, free ISA enabling a new era of processor innovation through open standard collaboration. Born in academia and research, RISC-V ISA delivers a new level of free, extensible software and hardware freedom on architecture, paving the way for the next 50 years of computing design and innovation.
For more detailed information please visit vendor site.
Examples are listed from RISC-V development platform repository:
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 using debug_tool options.
Boards listed below have on-board debugging tools and ARE READY for debugging! You do not need to use/buy external debugger.
