BSL 5525

Hi Satish,

I was a bit unsure from your questions what you were trying to do - are you trying to create a custom BSL in the BSL area of memory, for doing field firmware updates? Or are you trying to just load new firmware into your device using the existing USB BSL?

The two main resources for BSL are:

MSP430 Programming Via the Bootstrap Loader  - this tells how to load new firmware into your device using the existing BSL. There is a zip file that goes with it with code and tools like the BSL Scripter for communicating with the MSP430 BSL.

Creating a Custom Flash-Based Bootstrap Loader - this shows how to make your own custom BSL if you don't want to use the one that comes pre-loaded in the part. It also explains how the pre-loaded one works and has a zip file that goes with it with source code for the different BSLs.

For the USB BSL there is also:

USB Field Firmware Updates on MSP430 MCUs - this discusses different types of applications using USB for field firmware updates, and how to implement USB updates for these different models.

There is also this useful wiki page on MSP430 BSL: http://processors.wiki.ti.com/index.php/BSL_(MSP430)
