器件型号：TM4C1294NCPDT 工具与软件：
你(们)好
IAM 尝试 通过为自定义引导加载程序和自定义应用对闪存进行分区来通过以太网引导加载程序代码执行自定义固件升级
我所面临的问题是
固件升级后、非 RTOS 应用程序正常工作并正常引导
而 在固件升级中使用基于 RTOS 的应用程序,它会卡在下面提到的切换地址功能中
void SwitchAddress (uint32_t StartAddress)
｛
UARTprintf ("Start at %x\n"、StartAddress)；
IntDisable (INT_TIMER0A)；
IntDisable (INT_TIMER1A)；
IntDisable (INT_TIMER2A)；
IntDisable (INT_EMAC0)；
IntDisable (FAULT_SysTick)；
IntDisable (FAULT_NMI)；
IntDisable (FAULT_hard)；
//
//禁用所有处理器中断。 而不是禁用它们
//一次写入一个 NVIC 可以禁用所有功能
//外设中断。
//
HWREG (NVIC_DIS0)= 0xffffffff；
HWREG (NVIC_DIS1)= 0xffffffff；
HWREG (NVIC_DIS2)= 0xffffffff；
HWREG (NVIC_DIS3)= 0xffffffff；
HWREG (NVIC_VTABLE)= StartAddress；
//从应用程序的向量表加载堆栈指针。
_asm (" LDR R1、[r0]\n"
" mov sp、R1")；
//从应用程序的矢量表加载初始 PC 并分支到
//应用程序的入口点。
_asm (" LDR r0、[R0、#4]\n"
" bx r0\n");
}
我将共享引导加载程序和应用程序.CMD 文件

您能帮助我们检查.cmd 文件中的任何配置错误、或者对引导基于 RTOS 的代码所做的任何更改吗
