Supports multi-architecture bootstraps (assembly language) for various companies' microcontrollers such as RH850 and TriCore.
At Alive Vision Software, we develop a vehicle ECU reprogramming (reprogram) system and new reprogramming sequences that comply with the standards of various automobile manufacturers via CAN communication. Reprogramming requires an implementation that is deeply dependent on the individual architecture of the microcontroller, as the ECU itself switches control while operating to rewrite the firmware. Our company has been responsible for low-layer development of the bootstrap section (Boot section) for numerous major automotive microcontrollers in assembly language and C language, flexibly responding to specification changes and bug fixes. Additionally, we have extensive experience in adhering to strict quality management processes using various verification tools essential for automotive software development, such as CANoe, WinAMS, and QAC.
