Bootloader with reprogramming functionality for STM based electronic control units

Tema diplomskog rada je analiza, dizajn i implementacija programa za učitavanje operacijskog sustava sa reprogramirajućom funkcionalnošću za elektroničke upravljačke jedinice temeljene na STM mikrokontrolerima. Prvo se obradio program za učitavanje operacijskog sustava te su se definirale njegove značajke i funkcionalnosti. Zatim se obradio CAN protokol i njegova primjena u prijenosu podataka kod ažuriranja sustava. Nakon toga se definirao transportni protokol te se dao pregled popularnijih transportnih protokola koji bi se mogli primijeniti u ovom projektu. Odabrao se XCP uz obrazloženje izbora. Naposljetku se detaljno opisala implementacija sustava na STM mikrokontrolere uz primjer.The topic of the master thesis is the analysis, design, and implementation of bootloader with reprogramming functionality for electronic control units based on STM microcontrollers. The bootloader was first processed with its features and functionalities. The CAN protocol and its application in data transmission when updating the system were discussed. After that, the transport protocol was defined and an overview of the most popular transport protocols that could be applied in this project was given. XCP was chosen with the explanation. Finally, the implementation of the system on STM microcontrollers was described in detail with an example
