System Workbench for STM32

I have made some progress. I have tested from the J-Link command line and everything works as expected.

System Workbench now recognises the J-Link device, now my problem is that when I choose debug the most recently compiled binary (.elf) is loaded to my target and the program starts. Debugging is not enabled, the program continues to run and the debug window displays the following messages.

MyProgram GDB SEGGER J-Link Debugging
JLinkGDBServer
gdb
Semihosting and SWV

The Debugger console displays the following:
MyProgram GDB SEGGER J-Link Debugging ${cross_prefix}gdb${cross_suffix}(???)
