Abstract
A system and method for verifying that operating software and calibration files are present and valid after a bootloader flashes the files into the memory on a vehicle ECU before allowing the operating software to execute. The ECU memory defines a memory segment for the operating software and the calibration files. A software manifest is provided in a memory slot before the operating software segment in the memory. Likewise, a calibration manifest is provided in a memory slot before the calibration segment in the ECU memory. After the software has been flashed into the ECU memory, a software flag is set in the software manifest memory slot and each time a calibration file is flashed, a calibration flag for the particular calibration file is set in the calibration manifest.
