Design of bootloader in video analysis platform based on DM6446

摘要

On the base of Analyzing DM6446 different booting ways and UBL and U-Boot source code operating mechanism, Successfully transplanted UBL and U-boot to the intelligent video surveillance hardware platform, thus realized hardware platform's booting and operating system's startup. We described in detail the procedure and key technologies of transplanting U-Boot to the DM6446 platform. It is helpful to other embedded systems development.
