How to use vxWorks debugging tool to perform kernel kernel debugging?

Question

The vxWorks documentation says:

The WDB agent itself is independent of the target operating system: it connects to OS services at run time through the execution of a virtual function interface. The WDB agent can be executed before VxWorks starts (as in the early stages of porting a BSP to a new board).

How can I use the debug agent before starting the vxWorks kernel?

Answer 1

First, in order to be able to use the agent to perform pre-debugging, you must have a serial port for debugging. This serial port must be initialized and functional, as it will be a debug channel.
