@item -b @var{byte}
|
||||
@itemx --byte=@var{byte}
|
||||
Keep only every @var{byte}th byte of the input file (header data is not
|
||||
affected). @var{byte} can be in the range from 0 to @var{interleave}-1,
|
||||
where @var{interleave} is given by the @option{-i} or @option{--interleave}
|
||||
option, or the default of 4. This option is useful for creating files
|
||||
to program @sc{rom}. It is typically used with an @code{srec} output
|
||||
target.
|
||||
If interleaving has been enabled via the @option{--interleave} option
|
||||
then start the range of bytes to keep at the @var{byte}th byte.
|
||||
@var{byte} can be in the range from 0 to @var{breadth}-1, where
|
||||
@var{breadth} is the value given by the @option{--interleave} option.
|
||||
|
||||
@item -i @var{interleave}
|
||||
@itemx --interleave=@var{interleave}
|
||||
Only copy one out of every @var{interleave} bytes. Select which byte to
|
||||
copy with the @option{-b} or @option{--byte} option. The default is 4.
|
||||
@command{objcopy} ignores this option if you do not specify either @option{-b} or
|
||||
@option{--byte}.
|
||||
@item -i [@var{breadth}]
|
||||
@itemx --interleave[=@var{breadth}]
|
||||
Only copy a range out of every @var{breadth} bytes. (Header data is
|
||||
not affected). Select which byte in the range begins the copy with
|
||||
the @option{--byte} option. Select the width of the range with the
|
||||
@option{--interleave-width} option.
|
||||
|
||||
This option is useful for creating files to program @sc{rom}. It is
|
||||
typically used with an @code{srec} output target. Note that
|
||||
@command{objcopy} will complain if you do not specify the
|
||||
@option{--byte} option as well.
|
||||
|
||||
The default interleave breadth is 4, so with @option{--byte} set to 0,
|
||||
@command{objcopy} would copy the first byte out of every four bytes
|
||||
from the input to the output.
|
||||
|
||||
@item --interleave-width=@var{width}
|
||||
When used with the @option{--interleave} option, copy @var{width}
|
||||
bytes at a time. The start of the range of bytes to be copied is set
|
||||
by the @option{--byte} option, and the extent of the range is set with
|
||||
the @option{--interleave} option.
|
||||
|
||||
The default value for this option is 1. The value of @var{width} plus
|
||||
the @var{byte} value set by the @option{--byte} option must not exceed
|
||||
the interleave breadth set by the @option{--interleave} option.
|
||||
|
||||
This option can be used to create images for two 16-bit flashes interleaved
|
||||
in a 32-bit bus by passing @option{-b 0 -i 4 --interleave-width=2}
|
||||
and @option{-b 2 -i 4 --interleave-width=2} to two @command{objcopy}
|
||||
commands. If the input was '12345678' then the outputs would be
|
||||
'1256' and '3478' respectively.
