Flash Images to NAND under Linux (Mini6410)

After a year playing around with the mini2440 i orderd myself a 
mini6410.

Now my question is: how can i upload a image (u-boot, kernel, rootfs) to
the nand flash WITHOUT using windows?
I flashed a SD Card with superboot under windows, now i can boot in
bootloader mode and coud flash nand, upload etc, but 
under linux my device isnt recognize so that i could use
dnw2 or xdnw?

Is there another way?

found the error on my own:

i was using a OTG cable and that didnt worked. exchanged the mini-usb cable
now everything works fine. XDNW can upload files throug USB :)
