I've just successfully started using MSP430 devices with MSPGCC and the Python JTAG parport program. I wonder whether this Python program can also deal with the TMS470? It's a different architecture, so it would need a different flasher firmware, but I guess the JTAG part is much the same -- has anyone done any work on this so far?
i doubt that this works out of the box. the MSP430 JTAG interface allows accessing the internal data and address bus of the MCU. and exactly this feature is used to reprogram the flash. this is very MSP430 specific.
however, the JTAG hardware adapter could be be used for other systems as well if the signal levels/voltage matches. the HIL library that implements helper functions to work with the JTAG registers are hardcoded for 8/16 bit use an other architecture may need different sizes so you'll end up extending that library and implementing an other algorithm to program the flash, but it certainly possible. (i also abused the JTAG interface as SPI master. there is an example in the CVS/python folder you can definetly use that interface for more than just JTAG on the MSP430 ;-)
