Configuration
Please use hifive-unleashed ID for board option in “platformio.ini” (Project Configuration File):
[env:hifive-unleashed]
platform = sifive
board = hifive-unleashed
You can override default HiFive Unleashed settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest hifive-unleashed.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:hifive-unleashed]
platform = sifive
board = hifive-unleashed
; change microcontroller
board_build.mcu = fu540
; change MCU frequency
board_build.f_cpu = 1500000000L
Debugging
Debugging - “1-click” solution for debugging with a zero configuration.
Warning
You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.
You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).
HiFive Unleashed has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
