J-Link ARM JTAG Emulator is a JTAG emulator that supports ARM core chips, supports IAR EWARM, ADS, KEIL, WINARM, RealView and other integrated development environments, download speed up to ARM7: 600kB/s, ARM9: 550kB/s, maximum JTAG speed 12 MHz
This manual introduces the X-LINK J‑Link ARM JTAG emulator, a compatible alternative to SEGGER's J‑Link. It details core support for ARM7, ARM9 and Cortex‑M3 devices, connection methods with popular IDEs such as IAR, KEIL and RealView, and key features like high download speeds, USB power and multi‑device serial chaining.
Installation instructions cover driver download from SEGGER, ZIP extraction, and a straightforward wizard. An appendix provides a guide for using the built‑in GDBserver for debugging with GCC‑ARM toolchains. This manual is written in Chinese.
