Outputs multiple files for multiple memory banks.
--width
xbanks
Where:
banks
width
Valid configurations are:
--8x1 --8x2 --8x4 --16x1 --16x2 --32x1 --32x2 --64x1
fromelf uses the last specified configuration if more than one configuration is specified.
If the image has one load region, fromelf
generates the same number of
files as the number of
specified. The filenames
are derived from the banks
--output=
argument,
using the following naming conventions: destination
banks
= 1) the output file is named destination
.If there are multiple memory banks
(
> 1), banks
fromelf
generates
number of files named
banks
destinationN
where
is in the range N
0
to
banks
- 1. If you specify a file extension
for the output filename, then the number
is placed
before the file extension. For example:N
fromelf --cpu=8-A.32 --vhx --8x2 test.axf --output=test.txt
This generates two files named test0.txt and test1.txt.
If the image has multiple load regions, fromelf
creates a directory named
destination
and generates
files for each load region in that directory.
The files for each load region are named banks
where load_regionN
is the name of the load region, and
load_region
is in the range N
0
to
. For example:banks
- 1
fromelf --cpu=8-A.32 --vhx --8x2 multiload.axf --output=regions/
This might produce the following files in the regions
directory:
EXEC_ROM0 EXEC_ROM1 RAM0 RAM1
The memory width specified by
controls the amount
of memory that is stored in a single line of each output file. The size of each output file
is the size of memory to be read divided by the number of files created. For example:width
fromelf --cpu=8-A.32 --vhx --8x4 test.axf --output=file
produces four files (file0
, file1
,
file2
, and file3
). Each file contains lines of
single bytes, for example:
00 00 2D 00 2C 8F …
fromelf --vhx --16x2 test.axf --output=file
produces two files
(file0
and file1
).
Each file contains lines of two bytes, for example:
0000 002D 002C …
You must use --output
with this option.
