nsx view

Opens the SEGGER SWO viewer for a generated NSX app.

By default, nsx view starts the viewer first and then runs the app's normal SEGGER reset target once. This avoids a common race where SWO stays empty if the target is already running before the viewer is listening.

Syntax

nsx view [--app-dir APP_DIR] [--board BOARD] [--build-dir BUILD_DIR]
         [--toolchain TOOLCHAIN] [--no-reset-on-open] [--reset-delay-ms RESET_DELAY_MS]

Main Arguments

  • --app-dir: app directory containing nsx.yml
  • --board: override board from nsx.yml
  • --build-dir: build directory override
  • --toolchain: toolchain override (gcc, armclang). Defaults to nsx.yml → arm-none-eabi-gcc
  • --no-reset-on-open: open the viewer without issuing the normal reset target after attach
  • --reset-delay-ms: wait time before issuing the reset target after the viewer opens

Example

nsx view --app-dir <app-dir>

Notes

  • requires SEGGER SWO tooling in PATH
  • depends on the target being configured for SWO output
  • uses the board's normal SEGGER Reset flow by default; it does not require a stronger reset mode for Apollo510
