Vi+ 3.5 Loader Manual 5-13
for 16-Bit Processors
ADSP-218x DSP Loader/Splitter
ADSP-218x IDMA Loader Command-Line Reference
To create an IDMA boot file, use the following syntax for the ADSP-218x
loader’s command line.
elfspl21 sourcefile [ outputfile ] -218{x|1} -idma
Table 5-6 lists and describes each switch used in IDMA mode.
No Booting
In very rare cases, applications require that the DSP not be booted after
reset, or that the DSP is booted with a ROM connected to the DSP’s
off-chip DM/PM address space.
Preparing a non-bootable PROM image is called splitting. In most cases,
developers working with ADSP-218x DSPs use the loader instead of the
splitter. For ADSP-218x DSPs, splitter and loader features are handled by
Table 5-6. ADSP-218x DSP: IDMA Command-Line Switches
Switch Description
sourcefile
Specifies the executable file (
.DXE
) to be processed for a single-processor
boot-loadable file.
outputfile
Specifies the output file (
.IDM
).
-218{x|1}
Specifies the target processor:
•
-2181
—ADSP-2181 or ADSP-2183 DSP
•
-218x
—one of the ADSP-2184 through ADSP-2189 DSP.
When used with
-loader
, keeps the image.
-218{4|5|6|8|9}
Use in place of
-218x
. Specifies the ADSP-2184, ADSP-2185,
ADSP-2186, ADSP-2187, ADSP-2188, or ADSP-2189 DSP as a target
processor. Supports
PMOVLAY/DMOVLAY
.
-idma
Forces the loader to create an IDMA boot file. It overwrites most of the
BDMA boot-specific options.
