Hi

please be more detailed with your problem.
Are you using the IAR developing system!?

Perhaps the flash memory have some kind of problems!
Tries another device!!!

Yes im using IAR . But im able to download in other devices.
when i start downloading initial sequence on JTAG lines is correct . Im getting something on TDO line . so MSP is alive.
then wat could b reason.Its is MSP149

I'm also using MSP and sometimes it happens it cannot be programmed.

It is not clear if you use the JTAG interface or the bootloader.

If you use the boot loader then TI provides a program (with C sources) that you can use to download the code.

If you run the program in a debugger you can trace the problem.
