4.我的环境变量的offset 0x60000 size 0x20000,我的分区设置:
[0]=
{
.name="supervivi"
.size=0x80000
.offset=0x,
},
[1]=
{
.name='''kernel',
.offset=0x80000,
.size=0x200000,
}
[2]=
{
.name=''root',
.offset=0x280000,
.size=1024*1024*1024;
}
[3]=
{
.name=''nand',
.offset=0x00000,
.size=1024*1024*1024;
}
5.按照1的步骤,在SDRAM里面可以跑起来,打印如下:

6.将数据COPY到NAND里面去.
1)tftp 0x32000000 uImage
2)nand erase 0x80000 0x200000
3)nand write 0x32000000 0x80000 0x200000
上面就可以把核文件copy
4)tftp 0x31000000 ramdisk.gz
