Sorry, I probably use the wrong terms in my question. I do not mean
partition using file system,
but just saving files using the u-boot interface, for example saving the
kernel file in some space in the NAND and for the u-boot file in another
space in the NAND, and all done with the given write command in the uboot
(nand write...). And again with this u-boot interface I still need some
strategy for deciding where to put each file.

Thanks again,

Ran
