Debugging an embedded system—why is it crucial?
Debug and trace probes are essential tools for embedded development, enabling engineers to test, analyze, and optimize code directly on microcontrollers and other embedded systems. SEGGER’s J-Link and J-Trace models provide high-performance solutions for real-time debugging, breakpoint setting, and comprehensive trace analysis, giving developers deep insight into applications. With these tools, users can identify issues quickly, monitor program execution, and optimize the development process — all of which ensures efficient and reliable product performance.
SEGGER's debug and trace probes support a wide range of devices and development environments, making them versatile choices for embedded projects of all types.
J-Link debug probes
SEGGER J-Links are an industry-leading line of debug probes for embedded systems development. Known for their exceptional speed, reliability, and versatility, J-Links have become the go-to tools for developers around the world. For over two decades, these probes have been essential in enabling efficient debugging, programming, and performance analysis across a broad range of embedded applications and industries.
J-Link debug probes are the preferred solution for optimizing both the debugging and flash programming experience. Users benefit from record-breaking flash loaders, RAM download speeds of up to 4 MB/s, and the ability to set an unlimited number of breakpoints in microcontroller flash memories. This combination of speed, flexibility, and reliability makes SEGGER's J-Link an essential tool for anyone working in embedded systems — from hobbyists and students to professional developers.
