Yeh that is very strange. According to the log it is happening in the
beginning, even before romcc.c, and it is the oppasite of
-DROM_IMAGE_SIZE='0x17000' -DPAYLOAD_SIZE='0x-17000'

Very strange. It built locally just fine for me....

Thanks - Joe

The problem is right here:

from src/rca/rm4100/Config.lb:
if USE_FALLBACK_IMAGE
    default ROM_SECTION_SIZE = FALLBACK_SIZE
    default ROM_SECTION_OFFSET = (ROM_SIZE - FALLBACK_SIZE)
else
    default ROM_SECTION_SIZE = (ROM_SIZE - FALLBACK_SIZE)
    default ROM_SECTION_OFFSET = 0
end
default CONFIG_ROM_PAYLOAD_START = (0xffffffff - ROM_SIZE + ROM_SECTION_OFFSET + 1)
default PAYLOAD_SIZE = (ROM_SECTION_SIZE - ROM_IMAGE_SIZE)

and from src/rca/rm4100/Options.lb:
default ROM_SIZE = 512 * 1024
default ROM_IMAGE_SIZE = 128 * 1024
default HAVE_FALLBACK_BOOT = 1
default FALLBACK_SIZE = 512 * 1024
