    Siva,

    Please go through these sections, "Programming Flash Memory via the Bootstrap loader (BSL)" and "Programming Flash Memory via a Custom Solution", in the MSP430 user guide.

    Also please refer this page: http://focus.ti.com/lit/ug/slau319a/slau319a.pdf

    Hi..

    Thanks for reply..

    In my application UART data was coming from another controller..so is it really possible to done the flash write by using BSL or JTAG methods...Please clarify ..

    Hi siva,

    so, where's the problem? Your second controller needs to 'invoke' the BSL of your first controller (the one which you want to re-flash), send the commands to erase the flash, and then send your new firmware.

    Everything you need to know (commands, etc. is documented in the app note mentioned above.
