Under Linux, do I need DNW for Vivi usage?

Hi.

I am a Linux only guy, just starting out on Mini2440 development.
Reading the applicable docs on programming NAND it seems that a Linux user
has to run DNW.exe so as to get Supervivi to talk, upload, download via USB
correctly - Is this the case?

Has anyone got a Linux util that does the same?

Thanks.

Yes.  Supervivi = zImage.

Linux, you can use u-boot and convert zImage to uImage
or 
have a look at usbpush

I am not sure what files it handles.

Thanks Davef - I'll look into it and give it a try.
