    TI USB BSL is open source slau319 MSP430 Programming With the Bootloader (www.ti.com/lit/slau319).

    There is boot code that after power up / reset checking PUR pin and 0FFFFh location. If PUR pin is high or at address 0FFFFh is word 0FFFFh, device entering to BSL mode.

    Do you mean you want to know how to load object code to a device?

    Or, do you mean you want to know how to improve/enhance/expend the capability of an existing firmware?
