Hello, Can't we backup nand flash image of Mini6410 as we do it on Mini2440?
Mini6410 NAND Backup
I think you can, because, I remember seeing xdwn tool (the Linux equivalent of the windows DWN tool), being tested using a mini6410, i.e. if the google-translation of the README.txt file contained in the software package is interpreted correctly. The bootloader / options may be different. Don't own a 6410, so not sure.
