We use a BSL-module on MSP430F6725 and MSP430F6735 in our devices.
We used 9600 baudrate before. Now we need to make this process faster. We have investigated a communication protocol of GANG-programmer firmware updating. It was detected, that at the beginning GANG communicates with MSP on 9600 baudrate, and downloads some data into MSP. After that the speed is changed to 115200 and downloading process continues.
But Slau319.pdf says, that for F5x and F6x devices “The only supported baud rates are 9600 and 57600”. How is this possible?
So we have 2 questions:
1. What is the data downloaded into MCU by GANG on 9600 speed? We want to see this data, to realize how it can impact on stability and reliability of our device.
2. How can we implement bootloading process on speed 115200 whithout GANG?
