If it exists then zbarebox.bin please. There is a convenience link
(barebox-flash-image) which always points to the correct binary.

Hm, strange. This should be a Samsung 128MiB NAND flash. The id is in
the database. I currently have no good idea why this isa unknown.

For testing I would recommend the SD card. You can simply write the
binary to the card:

cat barebox-flash-image > /dev/sdx

The FCB is not part of the image. However, when you start from SD card
you should be able to use barebox_update to flash to the nand, given
that it works of course...
