Hi Team,

In my current project application, there is a need of firmware upgrade of MCU MSP430-FR-2476 using BSL- Rocket. For that i have installed BSL scripter (https://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSPBSL_Scripter/latest/index_FDS.html) in my linux laptop. I was trying to execute my firmware image (in txt) as shown below in snapshot, but could not get it worked. I am following BSL scripter user's guide. 

Can you please guide me step by step how to follow each and every step to upgrade my MCU with new firmare image?

    Hi,

    I could execute the UART script_FRxx_uart.txt and updated the script with offset and firmware binary name. The script_FRxx_uart.txt file looks as below for MSP430FR-2476,

    Below are the snapshots during BSL script exeuction for FW upgrade. The Unknown ACK Value! error is shown. Can you please suggest what is the wrong in my steps or i am missing?
