Reading memory of a T1042D4RDB (Memory Dumping?)

Hi,

I am working with a T1042D4RDB board and using a Codewarrior TAP probe. I'm still new to the Codewarrior development studio so I'm not completely sure of all the capabilities.

 

But essentially I'm trying to investigate how the JTAG port is a security hazard. To do this I just want to be able to actively read the memory with the probe and maybe even change memory values. But at the moment, all I know how to do is run a blank project, and add a memory monitor.

They description page for the TAP says "Offers complete system visibility and control, including reading/writing of CPU registers, memory mapped registers, block reading/writing of memories..." but I'm not sure how to go about this.

 

If I could create a memory dump that would be useful as well. With either the develop studio or maybe adding an option for it in the U-Boot start up menu?

 

Thank you.
