Your old fx35 image in FIS has a length 0f 0x00010000 but your new
image has a size of 0x002184bc - 0x00205000 (which is more than
0x10000). That means that only the first 0x10000 bytes of your new
image will be programmed to flash (and loaded to RAM afterwards).
Either try to create a new image (with a new name) or remove your
old fx35 image before creating a new one.
