The bootloader can be used to upgrade product firmware via the MCU communication port, with a low learning curve.
The Bootloader provided in this article integrates some UDS (14229, 15765 specifications) services with the TSMaster host computer and can download APP programs through the CAN FD interface.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The bootloader program will parse the data packets coming from the upper computer, combine the APP code packets and write them to the target Flash space in sequence.
After the APP program in the target Flash area is successfully started, the Bootloader program will automatically quit running and the APP will start working.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
