有网友来信要介绍一下Umon和nand在2416上的移植，时间有点久了，大概如下：
一. 需要实现三个文件：
SD卡启动的boot、Nand上启动的Boot、Umon。
二. SD-boot启动文件：
sd-boot主要代码如下，其中加载是利用了2416内置Irom提供的加载函数：
void Lcd_Off(void);
void Clk0_Enable(int clock_sel);
void Clk1_Enable(int clock_sel);
void Clk0_Disable(void);
void Clk1_Disable(void);
void ClearMemory(void);
volatile U32 downloadAddress;
void Uart_SendString(char *str);
volatile U8 dma_done=0;
int download_run=0;
volatile U32 tempDownloadAddress;
int menuUsed=0;
extern char Image$$RW$$Limit[];
U32 *pMagicNum=(U32 *)Image$$RW$$Limit;
int consoleNum;
/**
* This Function copies a block of page to destination memory.( 8-Bit ECC only )
* @param uint32 block : Source block address number to copy.
* @param uint32 page : Source page address number to copy.
* @param uint8 *buffer : Target Buffer pointer.
* @return int32 - Success or failure.
*/
#define NF8_ReadPage(a,b,c) (((int(*)(uint32, uint32, uint8*))(*((uint32 *)0x40004000)))(a,b,c))
/**

* @return int - Success or failure.
*/
#define NF8_ReadPage_Adv(a,b,c) (((int(*)(uint32, uint32, uint8*))(*((uint32 *)0x40004004)))(a,b,c))

/*
CopyMovitoMem(HSMMC_CHANNEL, MOVI_BL2_POS, MOVI_BL2_BLKCNT, (uint *)BL2_BASE, MOVI_INIT_REQUIRED);
HSMMC_CHANNEL这是SD/MMC通道号，手上板子运用的是CH1，而默认是CH0，所以须要对这个实行修改。
MOVI_BL2_POS 是须要 copy 的数据位于SD的起始扇区，其计算要领 是这样的，
先得到这个SD的总扇区数TOTAL，再减去256K的BL2和8K的BL1所占的扇区数，
结尾减去0.5K 的eFuse和0.5K的保存区所占的扇区数，
而这里还解释SD的扇区为512B。从这里能够看到和IROM_Fusing_tools对SD卡的处理是完全对应的。
这里还有一个疑问，总扇区数TOTAL是如何得到的？从程序来看是从(TCM_BASE - 0x4)这个地址读取到的，
至于TOTAL是如何 被放到这里的就只好从BL0的代码找答案了。
MOVI_BL2_BLKCNT是须要复制的扇区数目，这里就是解释为256K，
这也是为什么必须把u-boot.bin转换成256K的文件
BL2_BASE是目标地址，也就是SDRAM中的地址。这里解释为0x57E0000?
是128M 的SDRAM的结尾 2M，因为到这里为止MMU尚未打开，因此这里运用的是物理地址。*/

四. Umon的代码就好说了，把开发板上的拿过来修改下就行了，我这个做了一些有关nand的扩充。另外预定义__NANDBL不要设，现在代码上还有是没来得及删除这些东西。

五. sd-irom制作
sd-boot注意连接时的地址，编绎完的代码不能超过8K。然后用工具把文件扩充到8K，然后把sd-boot和umon的bin文件合并到一起，命令：
批处理命令：
copy /y ..\SD-BOOT\SDLoader.nb0 .
copy /b/y SD-Umon.bin+SDLoader.nb0 SD-IROM.nb0
pause
另附本人做的小工具下载地址：
http://ishare.iask.sina.com.cn/f/13568428.html
六. nand启动制作
用sd 启动后，把nand-boot和umon烧进去就ok了。
