Hello, I just point you into the right direction: you can launch the debugger standalone. The debugger itself is located in the prog folder, file hiwave.exe. The debugger has a set of scripting/command files. Basically what you need to do is to load the right configuration file (usually a project.ini). Such a file is created as well if you create a project in CodeWarrior using the new project/stationery wizard.
Simply launch the hiwave.exe with the corresponding .ini/configuration file, e.g. hiwave.exe -prod=myconfig.ini (see as well the other launch options described in the manual). There is as well a -cmd option: with this you can launch additional commands, e.g. loading a S-Record to the target. There are many commands available/described in the manual. Especially have a look at the LOAD command:
