Redlink (also known as Link Server) is the mechanism used by LPCXpresso to provide a debug connection down to a target MCU. It provides the means to connect to single MCUs or to multiple CPUs within the same MCU via a single debug probe.
Redlink consists of a number of layers which you may see referenced in various places within LPCXpresso when making debug connections. These include:
A number of Redlink compatible probes are available. These include:
Redlink is also used for communication to other CMSIS-DAP enabled debug probes. For more details, please see the FAQ "CMSIS-DAP support in LPCXpresso".
Note: From LPCXpresso IDE v8.1 Redlink/Linkserver is also the primary scheme used for connection to the LPC-Link and Red Probe+ debug probes.
Note that we have no plans to support debugging of ARM7/9 based parts with any 'redlink' connections (including CMSIS-DAP). To debug such parts, you will need to continue to use Red Probe+ or LPC-Link1 and connect via compatable debug drivers. LPCXpresso IDE will automatically select the correct mechinsm for such parts.
