Generic Zephyr Demo

The generic Zephyr demo works on any board with a J-Link debug probe. No Nordic-specific dependencies, no Bluetooth LE required. Use it to try LogScope on your own hardware. See supported boards for tested targets and J-Link setup instructions.

Quick Start

# nRF52840 DK
west build -b nrf52840dk/nrf52840 samples/zephyr-generic-demo -p
west flash

# nRF54L15 DK
west build -b nrf54l15dk/nrf54l15/cpuapp samples/zephyr-generic-demo -p
west flash

# STM32 Nucleo
west build -b nucleo_f401re samples/zephyr-generic-demo -p
west flash

Buttons

Uses standard Zephyr GPIO with sw0-sw3 devicetree aliases. Boards without buttons still run all periodic events automatically.

Button	Action
sw0	Sensor anomaly sequence
sw1	Flash corruption sequence
sw2	Stress burst (50 messages)
sw3	Reserved

Recurring Events

Same timing as the BLE HCI demo (heartbeat every 5s, sensor reads every 2s, retransmission warnings every ~8-12s, etc.) but without Bluetooth LE events.

Differences from BLE HCI Demo

Feature	Generic Demo	BLE HCI Demo
RTT logging	Yes	Yes
Button triggers	Yes (standard GPIO)	Yes (Nordic DK library)
Bluetooth LE	No	Yes
HCI packet decoding	No	Yes
Board support	Any Zephyr board	nRF54L15 DK only
Nordic SDK required	No	Yes (NCS v3.2.0)

Suggested Watch Patterns

Configure these watch patterns to highlight key events:

"logscope.watchPatterns": [
  { "name": "Errors", "pattern": "failed|error|fault|CRC|timeout", "regex": true, "color": "#f44336" },
  { "name": "Retransmission", "pattern": "Retransmission", "color": "#ff9800" },
  { "name": "Heartbeat", "pattern": "Heartbeat", "color": "#4caf50" }
]
