hi,

I want to boot from nand flash,so I need to flash uImage and file system to nand flash.

Now I know the adress where I need to write the uImage,it is 0xa0000,and use the command:

nand erase 0xa0000 $(filesize)

nand write 0x80700000 0xa0000 $(filesize)

I flash the uImage successfully.

Now I have a problem where I need to write the file system (ramdisk.gz) and what's the bootargs.I want to know the adress of nand flash that the file system should be in.

Or are there other methods to restore the 6467 Nand Flash?

Thank you!

Typically on the DM6467 EVM the file system is stored on the ATA hard drive as opposed to NAND flash, though this should also be possible. For writing a file system to the NAND flash you would typically do so from Linux on the device, for example see this wiki article which was written in regards to DM6446, it should apply similarly to the DM6467.
