we've a working design based on ML510 eval board and VxWorks 6.5. We can download applications from Workbench to the target and start these from the VxWorks command line. Unfortunately, when we start the debugger from Workbench to debug applications, the connection with the target is lost and the target hangs and must be restarted. The debugger is configured in task mode. The VxWorks image has been compiled with gnu tool-chain.
Did somebody successfully used the Workbench debugger in the past?
