The Porting Guide and the Users Guide offer more detail on the softwarecomponents and build information.The step in enabling trusted boot capability is the generation of trusted images, which requires thegeneration of the integrated verification module using the OEM keys. The integrated verificationmodule and binary are then packaged together. Once the image is packaged with the integratedverification module, a digital signature must be created and stored in the integrated verificationmodule. This creates a binary image ready to be downloaded or burnt to flash.12.2 Download ToolsThe Boot ROM supports downloading via USB or FFUART. See Table 1, Version 2.xx and Version3.xx High Level Differences, on page 15 for platform specific requirements.
