Supervivi Backup & Restore

Hello!

  I near the end of my mini2440 development project (yay me!) and I'm
looking for a good easy method for putting uboot, kernel, rootfs into the
NAND on the board. (something easy enough a monkey can do it...)

One of the items I've hit upon is using the:
[u] Backup NAND Flash to HOST through USB(upload) 
[r] Restore NAND Flash from HOST through USB 

...from the Supervivi menu.

If it works out, I can take a 'stock' mini2440 and in one swell foop turn
into a finished unit.

One to the query/help section:
Has anybody played with these?
How does one catch the output from the 'Backup NAND Flash'?
When using the 'Restore NAND Flash' option, does Supervivi take into
account the possible bad blocks?

Any generally helpful replies appreciated, thanks in advance.

> Has anybody played with these?

Yes.

What are you running to see the menu?  DNW? Then it just gets saved as a
file on your Windows box.

That's a good question!  I assume you can only restore to the machine you
backed it up from and then what happens if blocks go bad in the mean time. 
Sorry, can't help with that one.

A little followup:

DNW.exe (plus the Windows driver, and damn them for not having this
available for Linux!) works for catching the "Backup NAND through USB"
option.

However, the "Restore NAND" does not work.

// end output

Repeatedly.  Not sure why, no indicator of why it failed.  Seeing as I'm
running Windows virtualized, there's a chance something about the USB is
causing this failure, but I doubt it.

I'll keep fiddling with it, let you know if I get anywhere.  If anybody has
some suggestions please let me know, thanks.

Is yours a 1Gb mini2440?  I am sure it worked for me on a 64M machine, but
that was about 2 years ago.

Good luck!

Hi "bender b rodrigues",
I have the same problem as yours on restoring mini2440. Have you learn any
solution for that?
