Loader for ADSP-21161 SHARC Processors
Table 4-10. ADSP-21161 Loader Command Line Switches (Cont’d)
Switch Description
-h
or
-help
Command-line help. Outputs the list of command-line switches
to standard output and exits.
Combining the -h switch with -proc ADSP-21161; for example,
elfloader -proc ADSP-21161 -h, yields the loader syntax and
switches for ADSP-21161 processors. By default, the -h switch
alone provides help for the loader driver.
-hostwidth # Sets up the word width for the .ldr file. By default, the word
width for PROM and host is 8, for link is 16, and for SPI is 32.
The valid word widths for the various boot modes are:
PROM—8 for hex or ASCII format, 8 or 16 for include
format
host—8 or 16 for ASCII or binary format, 16 for
include format
link—16 for ASCII, binary, or include format
SPI—8, 16, or 32 for Intel hex 32 or ASCII format
-id#exe=filename Specifies the processor ID. The -id#exe= switch directs the
loader utility to use the processor ID (#) for the corresponding
executable file (filename) when producing a boot-loadable file
for EPROM boot of a multiprocessor system. This switch is used
only to produce a boot-loadable file that boots multiple processors
from a single EPROM.
Valid values for # are 0, 1, 2, 3, 4, 5, and 6.
Do not use this switch for single-processor systems. For single-processor
systems, use filename as a parameter without a
switch. For more information, refer to “Processor ID Numbers”
on page 4-23.
-id#ref=N Points the processor ID (#) loader jump table entry to the ID (N)
image. If the executable file for the (#) processor is identical to the
executable of the (N) processor, the switch can be used to set the
PROM start address of the processor with ID of # to be the same
as for the processor with ID of N. This effectively reduces the size
of the loader file by providing a single copy of an executable to
two or more processors in a multiprocessor system. For more
information, refer to “Processor ID Numbers” on page 4-23.
