Stupid me. Of course it was the wrong device file. MTD Devices have an 
even minor number (mtd->index*2). The odd minor (mtd->index* 2+1) 
number is used for readonly device files. Now I use the device 
file /dev/mtd5,c,90,10.

Now I get output from nanddump. But I cannot see the file contents that 
I wrote to the DoC.

testfile: "0123456789ABCDEF"

/> nandwrite -p /dev/mtd5 /mnt/testfile
MTD_open
MTD_ioctl
MTD_ioctl
Writing data to block 0
MTD_ioctl
Bad block at 0, 1 block(s) from 0 willM be skipped
Writing dataT to block 4000
D_ioctl
MTD_write
MTD_close

Seems to have worked. However nanddump (I dumped the complete 16 MB) 
does not show the file contents on the DoC.
Do I have to format the DoC or do any other preparation? I thought that 
was only necessary with the "old" driver.

This is also my next step. Preparing for a filesystem. I think I have to 
format it with the ntfl_format tool and then mkfs.jff2. Right?
