I have a target with 4 processors in a JTAG chain and am using JLink for the debug connection. Can arguments be added to the JLinkGDBSever command to target a particular device and byte offset? When using JLinkGDBServer the jtagconf argument would be added.
You might be using an older VisualGDB version then. Please ensure you update to v5.3 (or v5.4 Preview) and also install the latest Segger package via VisualGDB Package Manager.
