TM4C1294ncpdt 特定位置 呼叫 ROM 发生 FaultISR

各位前辈,目前使用TM4C1294ncpdt 呼叫ROM API发生一些问题

此问题如下,当呼叫test function会发生FaultISR.
test function 有定址 只要定址的位置小于0x7F000就不会有问题。

想问各位前辈是哪边设定有异常吗 谢谢

#pragma CODE_SECTION(test, ".flash_bl");  //0x0008F000
void test(void)
{

//BOOT Configuration (BOOTCFG);
// turn off SysTick and its interrupt before entering the boot loader!
SysTickIntDisable();
SysTickDisable();

ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);

HWREG(NVIC_DIS0) = 0x0;
HWREG(NVIC_DIS1) = 0x0;
HWREG(NVIC_DIS2) = 0x0;
HWREG(NVIC_DIS3) = 0x0;
HWREG(NVIC_DIS4) = 0x0;
