SystemView Tracing

Introduction

This is a library that adds support for using Segger SystemView tracing for ODP projects.

Usage

To get started with adding SystemView tracing to your Embassy application:

1. Add this crate to your Cargo.toml.

 systemview-tracing = { git = "https://github.com/OpenDevicePartnership/systemview-tracing", version = "0.1.0" }

2. Add this feature and enable the following dependencies:

[features]​
systemview-tracing = [​
    "systemview-tracing/tracing-enabled",​
    "embassy-executor/rtos-trace",​
    "embassy-imxrt/systemview-tracing",​
]

3. Initialize SystemView tracing by adding the following line to the beginning of your main function

systemview_tracing::init_tracing(system_clock_frequency)

Note: You can find system_clock_frequency by SYS_CLK_FREQ = CORE_CPU_FREQ / 2

4. Since the defmt_rtt crate cannot be used with this crate simultaneously, make sure to add this config flag before any defmt_rtt import:

#[cfg(not(feature = "systemview-tracing"))]
use defmt_rtt as _;
