| 摘 要： | 为了实现光电实时跟踪系统在脱机运行时用户代码上电自动加载，采用了ROM Bootloader加载方式。为了将全部的用户代码（>1KB）拷贝到L2 RAM中运行,引入了二次引导过程。文中分别在Non-BIOS 系统和BIOS 系统下编写了二次引导程序并在实际应用中得到了验证。实验证明，基于TMS320C6416的光电实时跟踪自引导系统，满足了系统的性能要求，在实际系统中运行稳定可靠。 |

| Abstract: | Aiming at implementing loading custom code automatically when the TMS320C6416 DSP runs offline in the Photoelectrical and real-time Tracking system，this paper adopts the way of ROM Bootloader. But in default mode，it can only copy 1KB data. It is necessary to write the secondary bootloader programmes so that the rest custom code in external ROM/FLASH could be copied into the high speed of DSP. In this paper the detailed secondary bootloader programmes are written detailedly in the Non-BIOS and the BIOS system. The experiments show the method described in this paper achieved complete success. The Bootloader based on TMS320C6416 is well realized and thus the design requirement on the real-time and reliable ability of the Photoelectrical and real-time Tracking System can be satisfied. |
