Updating Software using MSP430 USB BSL

Recommended Posts



We need some advice on updating MSP430F5529 program using USB BSL.
We want to add/update a small part of data to the current firmware through USB BSL.


But the problem is the BSL automatically performs a mass erase,

TI's Appl note(SLAA452B) mentions that the BSL password reside at addresses 0xFFE0 to 0xFFFF

which changes for every new program and fixing the ISR locations solves the problem of MASS Erase.


But we don't know how exactly do we Fix the ISR locations.

Could you please let me know if there is a reference or example on how to Fix the MSP430 ISR locations.
