Overview
About ULINKplus
The Arm ULINKplus goes beyond traditional debugging by combining JTAG/SWD debug, Serial Wire Viewer trace, integrated power measurement, and digital test I/O in a single adapter. The built-in current and voltage measurement capability correlates power consumption directly with code execution in the Keil MDK timeline view, enabling engineers to identify which functions, interrupts, and sleep transitions drive energy consumption, critical for battery-powered IoT and wearable device development.
Digital test I/O pins provide synchronization signals for external test equipment, enabling automated hardware-in-the-loop testing workflows where debug events trigger oscilloscope captures or test fixture actions. SWV trace with precise timestamps delivers real-time event tracing, data variable logging, and exception tracking without halting the CPU. The ULINKplus bridges the gap between pure software debugging and system-level power and timing validation, making it an essential tool for teams developing power-sensitive Cortex-M applications.

Arm's Agentic AI Push: What Indian Embedded Teams Can Actually Use Today
Arm has set out its platform strategy for the agentic era, putting inference everywhere it has compute. Indian embedded teams can start on that direction this quarter with the Cortex-M toolchain they already own: Helium, CMSIS-NN, Ethos-U and Vela, on boards you can order today.
Arm User-Based Licensing in CI/CD: armlm, Proxy Activation and What Breaks
A licensing failure in an Arm pipeline blocks the release branch and puts a firmware engineer on armlm output instead of driver code, up to seven days after the change that caused it. The reason: a UBL licence is a cached certificate valid for 7 days, not a checkout. Here is what that changes about pipeline design, and what to fix first.
