    That is a pretty ancient version of CCS.  Our current version is CCSv5.2.1.  There have been quite a few changes to the flashing tools over the past 7 years.  The best option would be to upgrade CCS to a newer version.  There is a trial version that you can download.  However you will need to figure out what JTAG emulator that is to see if there are drivers for it for newer CCS releases.

    The error may be addressed by just updating the flash API.  I found the following info searching around:

    From the TI web site (http://focus.ti.com/lit/an/spraab6/spraab6.pdf), the doc says: "The new F281x silicon version G requires Flash API V2.10 and will not operate correctly with Flash API V1.00. You will need to update the flash APIs to V2.10 in all areas, including product development, manufacturing, and any embedded software flashed onto the processor for field updates." "The REVID field for Rev G will be 0x0007 at memory address 0x883. Rev G devices will be symbolized as shown below. The ‘G’ represents the silicon version. TMS 320F2812AAAA CG-XXXXXXX"

    You can try installing the latest version of the flash plugin and API for CCSv3.x:
