Overview
About J-Link BASE Compact

The J-Link BASE Compact is SEGGER’s entry-level debug probe in its smallest commercial form factor, functionally identical to the standard J-Link BASE with no code-size limits on debugging. It runs the same J-Link firmware as the PRO and ULTRA models and draws on the same device database spanning tens of thousands of devices. The licensed software add-ons, Unlimited Flash Breakpoints, J-Flash, and the Ozone debugger, come with the J-Link PLUS and above, or via SEGGER’s BASE-to-PLUS upgrade.
Supporting Arm Cortex-M/A/R and RISC-V architectures with download speeds up to 1 MB/s, the BASE Compact handles everyday development workflows with ease. RTT provides high-speed bidirectional communication for debug output, SWO enables trace-based profiling, and GDB Server ensures compatibility with every major IDE and editor.
At just 46 x 46 x 17 mm and 20 grams, with USB-C connectivity and two mounting holes for direct integration into fixtures, the BASE Compact fits into any workspace, test rig, or end equipment. Free software and firmware updates ensure long-term value and ongoing compatibility with new silicon releases.

SEGGER J-Link and J-Trace Now Support Andes Trace: Why This Matters for RISC-V
SEGGER's J-Link and J-Trace probes now support Andes Trace, the hybrid N-Trace plus E-Trace instruction-trace solution built into Andes RISC-V cores. Here is what Andes Trace is, why probe-level support closes one of RISC-V's last serious tooling gaps, and what it means for Indian embedded teams.
Choosing a SEGGER Flasher: Standalone vs Gang vs Secure vs Portable
Standalone, gang, secure, or portable, the SEGGER Flasher family covers four different production-programming problems, not one. Here is how Indian engineering and production teams should decide.
J-Trace PRO vs TRACE32: An Honest Comparison for India
SEGGER J-Trace PRO delivers much of the same core streaming-trace capability as Lauterbach TRACE32 for Arm Cortex-M/A/R and RISC-V targets, at a lower cost point. Here is where each platform is the stronger fit for Indian engineering teams.
