TI中文支持网如题，我想把ubifs文件系统从nand flash中读出来，但是，我如何确定这个文件系统存储在nand flash的什么地址？
我是执行mmc_flash_ubifs进行烧录，我想问，如何确定在nand flash中的存储位置？
uboot环境变量如下：
bootargs=console=ttyS2,115200n8 ip=192.168.4.191 mem=64M@0xc0000000

感谢回复，但我是想把文件系统通过烧写nand flash的烧写器从nand flash中读取出来啊，我想确定当我们从SD卡拷贝文件系统写入到nand flash时，存放在nand flash中的地址
