| Abstract: | Based on three types of boot processes and the most commonly used ROM boot process, a basic flow of fast implementation of second-level bootloader in DSP application with encryption and decryption is proposed in this paper. Besides, problems which include the format conversion of DSP application program, how to work with Hex conversion utility, encryption and decryption of program data, bootloader's packing in ROM, and updating bootloader and DSP application program using emulator, are solved. The research result has applied to the Satellite Navigation and Positioning System. |
