My kwbimage looks similar:
VERSION 1
BOOT_FROM nand
DESTADDR 00600000
EXECADDR 006a0000
NAND_BLKSZ 00020000
NAND_BADBLK_LOCATION 01
BINARY arch/arm/boards/netgear-rn104/binary.0 0000005b 00000068
PAYLOAD ./payload
The other kwbimage.cfg files don't have a "PAYLOAD" line though, but if
I read the source correctly this shouldn't a problem.
BTW, is this binary.0 expected to be located in the source or the build
directory for oot-building? I would expect to provide it in the source
tree, but it's not picked up from there.

With the patch I just sent, kwboot doesn't take 30+ minutes anymore, but
dies when an error occurs. (Unfortunately this happens 100% reproducibly
with two different USB-to-RS232 adapters.)
Best regards
