Alexander, The MSP430 doesn't go into BSL mode automatically when a USB cable is plugged in. You have to detect this condition in your application and then make the jump into the BSL code. It might help us to help you if you could: 1. Briefly list your reprogramming scenario (use case) to describe how you envision your system getting programmed. 2. Post a snip of your hardware schematic showing how you have the USB port wired from MSP430 to the external connector. This is the most expeditious way to get a solution, so we don't spend time giving you bad advice based on an incomplete picture of what you need.
