Invoking the Bootstrap Loader by Software with msp430f6779

Hi baycan,

Please see the BSL User's Guide www.ti.com/lit/pdf/slau319 section 3.8.1 Starting the BSL From an External Application.  

Basically, you'll call this from your code when you want to enter the BSL:

__disable_interrupt();
((void (*)())0x1000)();

But I would still read the section to make sure you've covered all additional considerations.

Hope this helps!

Basically, you need to restore the start conditions (as the BSL will expect power-on defaults for the parts it uses), then call the BSL code. Even on MSPs with protected BSL area, the firs tfew bytes with the entry points are reachable. I don’t know the address off-hand (as it depends on the actual MSP), but in C you can do something like

((void (*)(void))0x1000)();

(Katie's version of the function call may result in compiler error about the missing function parameter)
