TM4C1294 EEProm读写问题

各位大侠：

        我在调试TM4C1294的Eeprom读写问题，一直都没有调通，哪位高手指点一下！

        时钟配置：

g_ui32SysClock = MAP_SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ |
                                                                          SYSCTL_OSC_MAIN |
                                                                          SYSCTL_USE_PLL |
                                                                          SYSCTL_CFG_VCO_480), 120000000);

        代码如下：        

        SysCtlPeripheralEnable(SYSCTL_PERIPH_EEPROM0);
        EEPROMInit();
        e2prodata.E2romFlg = 0x0555;
        EEPROMProgram((uint32_t*)(e2prodata.E2romFlg), EEPROM_BASE_ADDRESS, 4);
        e2prodata.E2romFlg = 0;
        EEPROMRead((uint32_t*)(e2prodata.E2romFlg) ,EEPROM_BASE_ADDRESS, 4);
        if(e2prodata.E2romFlg == 0x0555)
        {
               UARTprintf("Eeprom Read and write succeed.\n");
        }
       else if(e2prodata.E2romFlg == 0)
       {
               UARTprintf("Eeprom Read and write failed.\n");
       }

       感谢了！

找到一个例程，你可以参考看看。你是卡在哪一步了呢？你eeprom的地址是否正确。

     您好！如果我要改成120MHz是在这里改吗？

SysCtlClockSet(SYSCTL_SYSDIV_2_5|SYSCTL_USE_PLL|SYSCTL_OSC_MAIN|SYSCTL_XTAL_16MHZ); // islemcimizi 80 Mhz'e ayarlıyoruz.

Thanks and Best regards
