Something like

nandwrite -s 0x02000000 -p /dev/mtd0 test.txt

(mtd0 depending on which device your nandflash is)

(Note: you don't have to specify the padding size, nandwrite figures it 
out by querying mtd).

Something like

nanddump -o -b -s 0x02000000 -l <filesize> -f test2.txt /dev/mtd0

where <filesize> is the size of your file.
