How to use hex 80 in MSP430 bootloader (BSL) communication [Copy link]

Hex 80 is sent as a sync character before each transmission. The device acknowledges with hex 90. The data frame is then sent. Each frame begins with a header byte = hex 80. The other bytes of the frame follow the hex 80 header. The correct format for the BSL data frame is defined in the "MSP430 Bootloader Functionality" application note SLAA089 on the MSP430 website. A careful review of the code provided with the "Bootloader Application in MSP430 w/Flash - Hardware and Software Recommendations" application note SLAA096 shows that this is the best technique. The software and hardware in this application note have been tested and proven to work properly. TI does not directly provide specific tools to communicate with the bootloader. The application note "Hardware and Software Recommendations for Bootloader Applications in MSP430 Flash" SLAA096 contains proven software and circuit examples that can be easily built to connect to the bootloader. The application note "MSP430 Bootloader Functionality" SLAA089 also contains very useful information. These application reports are available through the MSP430 ti website. In addition, you can also visit the MSP430 website to find third-party companies that provide ready-made bootloader tools or solutions.
