There was a problem hiding this comment.
should come from wherever the start of the image is; which in flash binaries is affected by roll; and would be in RAM for RAM binaries (where i guess it must be at 0x20000000 in these cases)

Reads the entry point and stack pointer from the vector table, and adds them to the image_def as a new entry_point item. This is only done for signing Arm executable images.
This assumes that the vector table is at 0x10000000 unless a vector_table metadata item is present, which the SDK adds for no_flash binaries, so it should work with all SDK binaries.
