V9 Schematic: Jlink

: Genuine units use RSA digital signatures derived from unique hardware IDs to prevent firmware from running on non-Segger hardware.

The magic is entirely in the firmware. Segger’s intellectual property lies in how they manage the JTAG state machine inside the LPC MCU, how they handle the USB packet overhead, and their proprietary technology. RTT uses a ring buffer in the target MCU's RAM that the J-Link reads via background memory access—this is a software innovation, not a hardware one. jlink v9 schematic
