210从NAND复制代码到内存的只有前1K

我是smart210 3G 监控版，2G MLC nand flash的板子，现在在做uboot的启动代码，从nand复制代码到内存的时候，发现只有最前面1K正确复制了，
我在nand初始化部分代码如下

复制代码 //因为NAND的频率是200MHz 所以1HCLK=5ns #define NFCONF_TACLS (10<<12) #define NFCONF_TWRPH0 (10<<8) #define NFCONF_TWRPH1 (10<<4) #define NFCONF_ADDRCYCLE (1<<1) //注意一下因为我的开发版使用的是MLC所以以下参数设定 #define NFCONF_PAGESIZE (0<<2) #define NFCONF_MLCFLASH (1<<3) #define NFCONT_MODE (1<<0) #define NFCONT_NCE0 (1<<1) #define NFCONT_NCE1 (1<<2) #define NFCONT_NCE2 (1<<22) #define NFCONT_NCE3 (1<<23) #define NFCONT_SECCLOCK (0<<6) #define NFCONT_MECCLOCK (0<<7) #define NFCONT_RNB_TRANSMODE (0<<8) #define NFCONT_RNB_INT (0<<9) #define NFCONT_ENBILLEDALACCINT (0<<10) #define NFCONT_LOCK (0<<16) #define NFCONT_LOCKTIGHT (0<<17) #define NFCONT_MLCECCDIRECTION (0<<18) //初始化NAND void nand_init() {     //配置引脚-配置请见自己写的nand初始化文档     *MP0_1CON &= ~(0xff<<8);     *MP0_1CON |= (0x33<<8);     *MP0_1PUD &= ~(0xF<<4);          *MP0_2CON = 0x00002222;          *MP0_3CON &= ~0xFFFFFF;     *MP0_3CON |= 0x22222;     *MP0_3PUD &= ~(0x3ff);         //初始化NFCONF     *NFCONF &= ~(0xFFFF);     *NFCONF |= (NFCONF_TACLS | NFCONF_TWRPH0 | NFCONF_TWRPH1|NFCONF_ADDRCYCLE|NFCONF_PAGESIZE|NFCONF_MLCFLASH );     //使能NAND Controller //    *NFCONT &= ~(0x707C7);     *NFCONT = (NFCONT_MODE|NFCONT_NCE0|NFCONT_NCE1|NFCONT_NCE2|NFCONT_NCE3|NFCONT_RNB_TRANSMODE|NFCONT_RNB_INT|NFCONT_MECCLOCK \                 | NFCONT_SECCLOCK | NFCONT_ENBILLEDALACCINT | NFCONT_LOCK | NFCONT_LOCKTIGHT | NFCONT_MLCECCDIRECTION );     //复位NAND     nand_reset();      }

然后做页复制

复制代码 #define NAND_PAGE_SIZE 4096 #define BL1_SIZE (16 * 1024)  //定义BL1的大小，BL2在此地址之后 #define BL2_SIZE (48 * 1024)  //定义BL2的大小，决定要复制多少代码 #define CONFIG_SYS_BOOT_BASE (0x20008000)  //BL2复制到内存的基地址 #define NF8_ReadPage_Adv(a,b,c) (((int(*)(unsigned int, unsigned int, unsigned char*))(*((unsigned int *)0xD0037F90)))(a,b,c)) void copy_bl2_to_ram(void) {     void (*BL2)(void);     /**********************************************************     * 因为BL0会自动把前16K放进IRAM所以我们从NAND的16K偏移处开始复制代码     * 之前使用自己寫的NAND copy函數不知道為什麼不好使     * 改成固化代碼試試     ************************************************************/     ///********以下這段使用BL0固化好的代碼************     int i = 0;     int pages = BL2_SIZE / NAND_PAGE_SIZE;        // 多少页     int offset = BL1_SIZE / NAND_PAGE_SIZE;            // u-boot.bin在NAND中的偏移地址(页地址)     int block,page;     unsigned char *p = (unsigned char *)CONFIG_SYS_BOOT_BASE;     for (; i < pages; i++, p += NAND_PAGE_SIZE, offset += 1)     {         block = offset / 64;         page = offset % 64;         NF8_ReadPage_Adv(block,page , p);     }     BL2 = (void *)CONFIG_SYS_BOOT_BASE;     (*BL2)();      }

但是发现复制到内存的部份，内存中只有前1K内容是正确的，请问有知道的吗

自己发现了应该是mlc的问题，mlc因为是双倍密度在1k后面的数据居然跳了1k也就是 0x1000的数据跑到了0x2000位置处了，
还没解决不过找到病根了
