Revision as of 01:54, 8 February 2018
The TYPE tag is a 32-bit unsigned integer (uint32_t
) that when viewed in little-endian format, states the type of firmware image the IMG2/IMG3/IMG4/IM4P file is. Is is compared with the second parameter of image_load
(register r1
[1]). If it does not match, image_load
will fail and the image will not be loaded. If 0
is passed in r1
, then the check is skipped.
