I-jet Trace for Arm Cortex-M
适于 Arm Cortex-M 的调试和跟踪探针，赋予了 IAR Embedded Workbench 强大的功能。
01
广泛的调试
集成式工具简化了您的开发工作流程。我们功能丰富的在线跟踪调试探针赋予了 IAR Embedded Workbench for Arm 强大的功能。对嵌入式跟踪宏单元 (ETM) 的支持充分实现了代码覆盖和对时间轴中应用的调用堆栈图进行分析。
02
一流的性能
I-jet Trace for Arm Cortex-M 通过 JTAG 和 SWD/SWO 提供快速调试平台，下载速度高达 3.73M 字节/秒，支持速度高达 200MHz 的 SWO。JTAG 和串行线调试 (SWD) 的时钟高达 100MHz（对 MCU 的时钟速度没有限制）。
03
对 Arm Cortex-M 的广泛支持
支持所有半导体供应商的所有 Arm Cortex-M 内核，具有自动内核识别和 JTAG/SWD 检测功能。完全支持嵌入式跟踪宏单元 (ETM) 跟踪。
04
广泛的跟踪能力
I-jet Trace for Arm Cortex-M 配备了 SuperSpeed USB 3.0 接口，从探针到 C-SPY 调试器的数据传输速度高达 5Gbps。该探针有 64M 字节或 256M 字节版本，以满足不同的跟踪内存大小的需求。要收集跟踪数据，可以用 1、2 和 4 位的 150MHz ETM 跟踪时钟和 64 位的时间戳（具有 CPU 周期的准确性）进行。内含的流式跟踪功能可以实现无限的代码覆盖和剖析。
