Vi+ Loader Manual 2-43
for 16-Bit Processors
Blackfin Processor Loader/Splitter
-h
or
-help
Invokes the command-line help, outputs a list of command-line
switches to standard output, and exits. By default, the
-h
switch alone
provides help for the loader driver. To obtain a help screen for your
target Blackfin processor, add the
-proc
switch to the command
line. For example: type
elfloader -proc ADSP-BF535 -h
to
obtain help for the ADSP-BF535 processor.
-ghc #
Specifies a 4-bit value (global header cookie) for bits 31–28 of the
global header.
-HoldTime #
Allows the loader to specify a number of hold-time cycles for
PROM/Flash boot. The valid values (#) are from
0
through
3
. The
default value is
3
.
Note: Currently supported only for ADSP-BF535 processors.
-init filename
Directs the loader to include the initialization block from the named
file. The loader places the code from the initialization section of the
specified .
DXE
file in the boot stream. The kernel loads the block and
then calls it. It is the responsibility of the code within the block to
save/restore state/registers and then perform a RTS back to the ker-
nel.
Note: This switch cannot be applied to ADSP-BF535 processors.
-kb prom
-kb flash
-kb spi
Specifies the boot mode (PROM, Flash, or SPI) for the boot kernel
output file if you select to generate two output files from the loader:
one for the boot kernel and another for the user application code.
This switch must be used in conjunction with the
-o2
switch.
If the
-kb
switch is absent on a command line, the loader generates
the file for the boot kernel in the same boot mode as used to output
the user application code file.
-kf hex
-kf ascii
-kf binary
Specifies the output file format (hex, ASCII, or binary) for the boot
kernel if you select to output two files from the loader: one for the
boot kernel and another for user application code.
This switch must be used in conjunction with the
-o2
switch. If the
-kf
switch is absent from the command line, the loader generates the
file for the boot kernel in the same format as for the user application
program.
