Configuration

Please use swervolf_nexys ID for board option in “platformio.ini” (Project Configuration File):

[env:swervolf_nexys]
platform = chipsalliance
board = swervolf_nexys

You can override default RVfpga: Digilent Nexys A7 settings per build environment using board_*** option, where *** is a JSON object path from board manifest swervolf_nexys.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:swervolf_nexys]
platform = chipsalliance
board = swervolf_nexys

; change microcontroller
board_build.mcu =

; change MCU frequency
board_build.f_cpu = 320000000L

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).

RVfpga: Digilent Nexys A7 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
