Wenbin,
Thank you for your reply. I would certainly request that ability to invoke code generation from CLI be added to GUI Guider. Any build automation process will depend on it.
I am trying to work a GUI Guider project into an automated build environment, the output of which is linked into an MCUXpresso project, itself automated. Depending on manual code generation is very sub-optimal, as it places a human dependency in the middle of the build and opens up the possibility that the generated code becomes desynchronized from the GUI Guider project, which in turn will require an extra process step by the team lead to guard against.
