CCS/TMS570LC4357：TMS570LC4357：引导加载程序应用跳转至 SVC 条目。

最近我正在处理 TMS570LC4357上的 UART 启动加载程序。 我找到了 TI 自己的一个示例。

引导加载程序位于组0中、应用程序位于组1中。

从引导加载程序切  换到应用程序工作正常,但当进入应用程序并调用  OS_StartScheduler ()时,此操作不起作用。

正如我从文档知道的,"器件只支持一个异常矢量表,位于闪存的开头(0x00000000)。 当我的应用程序中发生一个 SVC 异常时、代码会转移到0x0000000中异常表的0x08"。

我的应用程序起始地址: APP_START_ADDRESS 0x00200100
