Splitter Command Line
Table 7-2. Splitter Command-Line Switches (Cont’d)
Item Description
-r # [# …] The -r (PROM widths) switch specifies the number of PROM files
and their width in bits. The splitter utility can create PROM files for
8-, 16-, and 32-bit wide PROMs. The default width is 8 bits.
Each # parameter specifies the width of one PROM file.
Place # parameters in order from most significant to least significant.
The sum of the # parameters must equal the bit width of the destination
memory (40 bits for DM, 48 bits for PM, or 64 bits for 64-bit
memory).
Example:
elfspl21k –dm –r 16 16 8 myfile.dxe
This command extracts data memory ROM from myfile.dxe and
creates the following output PROM files.
myfile.s_0—8 bits wide, contains bits 7–0
myfile.s_1—16 bits wide, contains bits 23–8
myfile.s_2—16 bits wide, contains bits 39–24
The width of the three output files is 40 bits.
-ram The -ram (include RAM in PROM) switch directs the splitter utility
to extract RAM sections from the inputfile. The -dm, -pm, and -64
switches select the memory. The -s switch is not influenced by the
-ram switch.
-f h
-f s1
-f s2
-f s3
-f b
The -f (PROM file format) switch directs the splitter utility to generate
a non-bootable PROM image file in the specified format.
Available selection include:
h—Intel hex-32 format
s1—Motorola EXORciser format
s2—Motorola EXORMAX format
s3—Motorola 32-bit format
b—byte stacked format
If the -f switch does not appear on the command line, the default
format for the PROM file is Motorola 32-bit (s3).
For information on file formats, see “Build Files” on page A-5.
-s section_name The -s (include memory section) switch directs the splitter utility to
extract the contents of the specified memory section (section_name).
Use the -s section_name switch as many times as needed. Each
instance of the -s switch can specify only one section_name.
Warning: Do not use -s with (-pm, -dm, or -64).
