| 摘 要： | 在基于TMS320DM642 D6P的应用系统中。当应用程序代码量超过1K byte时，上电复位后，需要通过二级引导程序将存储在FLASH中的应用程序代码引导到DSP内部RAM。根据二级引导程序的引导机制实现二级引导程序的开发。并使用三个通用I／O口,对整个FLASH空间进行分页。实现了地址的重映射。利用16进制转换工具自动生成可以用来帮助二级引导装载程序引导代码的引导表。

| Abstract: | If the size of an application programme for a system based on TMS320DM642 DSP is greater than 1 K bytes, senondary bootloader is needed to copy the application from FLASH to RAM once the power is on and the system is resetted. The senondary bootloader could be developed based on its own boot mechanism.. Three GPIO pins are used to divide the whole space of the FLASH to pages, so the address can be remapped.. The boot table which will be necessary for booting code could be generated automatically by hex conversion. |
