写了个裸机代码，通过DNW去下载到板子上，却不能运行，大牛帮忙分析分析下，具体操作步骤：
(1)选择1：Download to flash
(2)选择3：烧写到myApp分区
(3)通过DNW连接USB进行烧写
Now download and write nand flash part [ MyApp ]
press [USB Port-->transmit] to choose the file

Now, Downloading [ADDRESS:30800000h,TOTAL:1046]
RECEIVED FILE SIZE: 1046
(156.0KB/S,0.0S)
Now, Checksum calculation
Download O.K.

Now write nand flash page 0x300 from ram address 0x30800000, filesize = 1046
.Program nand flash partition success

(4)烧写完成后选择3：Boot My Application
出现问题：
NAND ID is 0xecda
Memory Test(30200000h-33ff0000h):O.K.
Load Application...
run 0x32000000...
NAND ID is 0xecda
Set boot params = root=/dev/mtdblock3 init=/linuxrc load_ramdisk=0 console=ttySAC0,115200 mem=65536K devfs=mount display=lcd480
Load Kernel...

貌似没有运行myAPP分区的代码，去启动内核了，大神有遇到过这种问题吗？？？
