If you are not flashing correctly, SPL does not run. It looks like that
your board boots (SPL runs).

erasesize = 1 ??

This larger NAND cannot be recognized correctly - it is not a problem by
flashing.

You have to investigate why this NAND (even if ONFI) is not recognized,
but it is a different problem as the one you reported previously.
