DM8127调试nor flash擦写出错，提示“no source available for "0x4030fc10" ”.

        我自己画的板子，调试裸机程序，连接了一片64Mbit 16位nor flash，由于连线错误，现只能当做8位flash调试。但执行完FLASH配置后，一执行擦除命令就出错，提示“no source available for "0x4030fc10" ”，请问是哪的问题？

我的配置如下：

CM_ALWON_GPMC_CLKCTRL = 0X02;

GPMC_SYSCONFIG = 0X0;

GPMG_IRQENABLE = 0X0;

GPMC_TIMEOUTCTRL = 0X0;

GPMC_CONFIG = 0X0;

GPMC_CONFIG1_0 = 0X00000010;

GPMC_CONFIG2_0 = 0X00101080;

GPMC_CONFIG3_0 = 0X00020201;

GPMC_CONFIG4_0 = 0X0F031003;

GPMC_CONFIG5_0 = 0X000F1111;

GPMC_CONFIG6_0 = 0X0F030080;

GPMC_CONFIG7_0 = 0X00000F01;               //flash base address = 0x01000000;

GPMC_CONFIG7_0 = 0X00000F41;
