The simulated flash driver will bus fault if the flash device has not been written at the address of the first image. This can easily be recreated by erasing the flash, and then not programming an image in.

The datasheet for the device lists a possible way to use the controller to read without causing a fault, and the ECC register can then be used to determine if the read was successful.
