MAKEROM
11.1 Overview
The MAKEROM tool builds a ROM image by adding header information to the
input files. Each input file generates one header plus the image, which is then
concatenated and written to the output file. These headers are used by the SROM and
other software to identify an image contained in the ROM. MAKEROM can also
compress these input files using a simple repeating byte compression algorithm. The
decompression code is provided in the SROM. Other improved compression
techniques that embed appropriate decompression code can also be used, such as the
HFCOMP tool.
11.2 ROM Header Information Fields
The ROM header information placed at the beginning of each ROM image contains
the fields shown in Figure 11–1.
