Perfect, problem solved. Anyway, I would be really interested in your kwb cfg file as it is probably image layout which reveal this issue.
It's a very basic configuration, inspired from board/mikrotik/crs3xx-98dx3236/kwbimage.cfg.in but for NAND booting:
VERSION 1 BOOT_FROM nand NAND_BLKSZ 00020000 NAND_BADBLK_LOCATION 00 BINARY ./board/qnap/qsw-98dx3236/binary.0 0000005b 00000068
I can't upload the actual KWB images I'm using because this is using a DDR3 training blob extracted from my vendor's build and I'm unsure about the licensing. But here's a complete hexdump diff of the images (before: without this patch, after: with this patch + the checksum fix).
