How to clone flash memory over JTAG connection?

I am a computer software programmer. I am trying to deal with some basic electronic concepts.
I have an onboard TMS320F243 which needs to be cloned.

I currently have the following setup…

1. I have installed XDS100v2 driver over USB
2. I have connected the XDS100v2 emulator throughout JTAG connection
3. I have Code Composer Studio v5 installed ( I also have ver 3.3 installed)

Unfortunately F243 does not exist in search.

I need to CLONE contents of one particular TMS320F243

HOW DO I READ contents of one particular TMS320F243 ?

HOW DO I WRITE this content to some other TMS320F243 ?

I don’t need to do anything else I just need a backup of my TMS320F243.

I want to …

• connect throughout the JTAG connection
• get data inside TMS320F243 to
• write it to a file rewrite it to another TMS320F243.

Which software should I use?

Is there simple software just for cloning purposes?
