What SEGGER Ozone is
SEGGER Ozone is a graphical debugger and performance analyzer for embedded applications targeting Arm and RISC-V processors. It provides source-level debugging for C, C++, Rust, and Assembler, alongside instruction trace, code profiling, and code coverage tools. Ozone works with J-Link and J-Trace probes and can connect to third-party probes or simulators through a GDB server. Supported toolchains include Embedded Studio, GCC-based IDEs, Clang/LLVM, IAR, and Arm Compiler. RTOS plug-ins and a SmartView interface support work with RTOS software and middleware; target terminal I/O is available through RTT, SWO, and semihosting. Scripts and a console interface can automate nearly all graphical actions, including event-triggered ones. Ozone runs on Windows, macOS, and Linux and supports remote debugging and conditional and exception breakpoints. Commercial use requires a perpetual Commercial-use License. The single-user license is €798, paid once, includes a 12-month Support & Update Agreement, and excludes German sales tax.
