TMS320F28379D: TMS320F28379D CPU2 FLASH操作故障

Part Number: TMS320F28379D

 F28379D 双核，自定义 Bootloader ，在CCS内仿真时正常工作，使用FREE RUN模式测试通过.

CPU2 烧录在脱离 CCS 仿真（Flash 直接引导）时失败,CPU1正常。

在执行擦除时,

g_nModbusRegister[0x78] = HWREG(FLASHPUMPSEMAPHORE_BASE); 返回值为0x0001 ;

g_nModbusRegister[0x75] = (uint16_t)(oFlashStatus & 0xFFFF); 返回值为0x0810 ;

g_nModbusRegister[0x76] = (uint16_t)((oFlashStatus & 0xFFFF0000) >> 16);返回值为0x0000 ;

g_nModbusRegister[0x74] 返回值为0x0000 ;

g_nModbusRegister[0x77] 返回值为0x0000 ;

CCS仿真引导和    Device_bootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH);引导可能在什么方面的差别会导致这个问题
