RTT provides for bidirectional, high-speed Terminal I/O (printf), setting an unlimited number of breakpoints even when debugging in flash memory, instruction trace, and ultra-fast flash download with J-Link/J-Trace. In addition to Segger RTT, other basic terminal I/O techniques such as ARM's Serial Wire Output (SWO) and semihosting are also supported.
J-Link Debugger can load applications/ELF files built with any compiler or even debug the target’s resident application without any source files being available. It is also fully controllable via script files making it a suitable solution for automated test setups. Instruction trace is also available in J-Link Debugger, allowing to view the stack of most recently executed machine instructions. This allows a better means of debugging complex problems and bugs.
The J-Link Debugger has been designed for the advanced set of Segger’s J-Link debug probes. This includes the J-Trace, J-Link PRO, J-Link ULTRA+, and J-Link PLUS. Other J-Link models may be used with the evaluation version of the J-Link Debugger.
