Version 3.2.x Boot ROM Reference Manual
3.1 Image Module Format
Table 5:
The Image Module format for the boot operation consists of the structures described in this section.
Table 5 provides information on required fields and optional fields for NTIM headers. The constant
part of the Image Module (CTIM struct) is defined below. This structure is used to calculate
dynamically the size of the NTIM. The structures IMAGE_INFO (or IMAGE_INFO_3_1_0 for NTIM
v3.1), and KEY_MOD are stored as arrays of structures. The size of the array is specified by the
NumImages and NumKeys variables, respectively, in the constant part of the NTIM. The
SizeOfReserved variable is used to specify the number of reserved bytes stored in the NTIM header
for optional parameters.

{ VERSION_I VersionBind;
FLASH_I FlashInfo;

unsigned int NumKeys;
unsigned int SizeOfReserved;

Based on the information in the CTIM structure, the NTIM can be sized using the following
calculation:
• Size of NTIM = sizeof(CTIM) + (NumImages * sizeof(IMAGE_INFO)) + (NumKeys *
sizeof(KEY_MOD)) + SizeOfReserved
Optionally, a master structure such as the NTIM structure below could be used to set pointers to the
start of each section of the NTIM. The SetTIMPointers() below show C code examples. The
SetTIMPointers() check the version of the NTIM to determine which Image information structure to
use. Two versions of the NTIM header are currently supported: version 3.1.x (0x00030100) and
version 3.2.x (0x00030200). The version identifier determines features supported in the header.
