RV-LINK¶

RISC-V emulator implemented with RISC-V development board. Unlike other emulators: RV-LINK interacts directly with GDB via a USB serial port and does not require an intermediary such as OpenOCD. Official reference can be found here.

Configuration¶

You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):

[env:myenv]
platform = ...
board = ...
debug_tool = rv-link

If you would like to use this tool for firmware uploading, please change upload protocol:

[env:myenv]
platform = ...
board = ...
debug_tool = rv-link
upload_protocol = rv-link

More options:

  • Debugging options
  • Upload options
