<num> parameter: numeric string
0, 1, 2, 3

image 0

DESCRIPTION: If <num> is not specified, 0 is assumed.
Without options, the NBL Flash memory is programmed using the
contents of the data buffer. If no image is available in the data buffer,
programming is terminated.
If no offset option (“-o”) is specified the image is added along with the
CRC and length information.
Normally, the local data buffer holds the image to be programmed.
However, if the “-m” and “-l” options are specified, the image is
programmed from the absolute address specified.
