Did you check that the flash geometry (page size / erase size) match the
flash device on your board? That would make the jffs2 image different in
content but not much in size as you see.
It's the "flash type" option in buildroot.
Parallel flash = NOR.
AT45 = SPI DataFlash from Atmel.
NAND flash = the usual these days.
Or you can go the custom way if one of the predetermined values doesn't
match your flash device.
