[oselas] Barebox gives error at "update -t barebox -d nand"

[Wingston]

i managed to get the barebox onto the nand via ftp once. but when i tried it 
after a while, it  got hung at 


mini2440:/ update -t barebox -d nand                                            
                                    host192.168.1.1 is alive                    
                                                                                
Erasing partition /dev/nand0.barebox.bb                                         
                                                                                
dev/nand0.barebox.bb                                                            
                                                                                
FTP fromserver 192.168.1.1 ('barebox-mini2440' ->'/dev/nand0.barebox.bb') 

and then after this a pipe keeps rotating like a progress bar but nothing 
happens.. i dont get the hashes that i got before and my barebox does not get 
into nand.

is there a way to clean up the tftp settings on my ubuntu 11/04' because i 
think 
thats the problem there..
