I have finally managed to get the FET talking to my board! I downgraded the FET to V2 and then upgraded it again to V3 using TI's MSPFlasher. Now I can make a JTAG connection to the board using both MSPFlasher and mspdebug.
I have one more query related to this. My board comes pre-programmed with software from the vendor and is functioning properly. Now before I start playing with it, I want to read out an image that I can use to restore the board to its working state if I mess up. Looking at the memory map of MSP430F5528 in the data sheet, the flash memory starts at 0x4400. So doing a "hexout 0x4400 0xbbff defaultimage.hex" on mspdebug prompt will give me a restorable image? Or do I have to do something else to achieve this?
