Why can't register FRAM be written. The CCS is 12.1.0. The example cannot else.

你好，我想在指定的FRAM区域写数据。
首先定义了首地址
#if defined (__TI_COMPILER_VERSION__)
#pragma PERSISTENT(FRAM_TEST_START)
uint32_t FRAM_TEST_START =
#elif defined (__IAR_SYSTEMS_ICC__)
__persistent uint32_t FRAM_TEST_START =
#elif defined (__GNUC__)
__attribute__ ((section (".persistent"))) uint32_t FRAM_TEST_START =
#endif
0x5500;
将地址与数据传入函数开始写如指定位置
uint32_t * FRAMCtl_A_Memory32 (uint32_t *value,uint32_t *framPtr,uint16_t count)
{
uint16_t i=0;
while (count> 0)
{
*framPtr = i;
i++;
count--;
framPtr++;
}
return framPtr;
}
仿真观察对应地址，发现寄存器值没有改变
