What is J-Link?

J-Link debug probes are the most popular choice for optimizing the debugging and flash programming experience. Benefit from record-breaking flash loaders, up to 4 MB/s RAM download speed and the ability to set an unlimited number of breakpoints in the flash memory of MCUs.

J-Link also supports a wide range of CPUs and architectures. Everything from single 8051 to mass market Cortex-M to high-end cores like Cortex-A (32- & 64-bit).

J-Link supports directly interfacing SPI flashes, without the need of a CPU between J-Link and the SPI flash (directly communicating via the SPI protocol). J-Link is further supported by all major IDEs, from free Eclipse-based ones (directly or via GDB) up to commercial ones, including SEGGER Embedded Studio.
