Using IAR IDE for building ARM executables from C source, I can see the disassembly, including labels, addresses, opcode and instructions in the relevant window.
I am trying to dump the contents of a range of addresses to a text file, but can't find a way to do that. The window text is not selectable so I cannot use copy/paste. There is no menu associated that enables this.
As an alternative, I can generate the list and assembly files, but these seem to be limited to my code, and do not contain the CRT code or any ROM sections, which I am interested in.
Any way to dump a selected address range?
You want to use ielfdumparm located in your Workbench directory under arm/bin. Here's the help for the tool.
Usage: IElfDump input_file [output_file]
Available command line options:
--all Dump all sections
--code Dump only code sections
--no_header Do not produce a list header
--no_rel_sections
Do not output associated .rel sections
--no_strtab Do not include strtab sections
--output file
-o file Name of text file to create
--raw Use raw text format
--section #|name[,...]
-s #|name[,...] Dump only section(s) with given numbers/names
--source Include source in disassembled code in executables
--use_full_std_template_names
Don't use short names for standard C++ templates
-a All sections, except strtab sections
-f file Read command line options from file
To get a similar output to the debug view, I would suggest --code to avoid dumping your data space, and --source to have it embed your original C woven in with the assembly.
You can specify sections, but it doesn't look like you can specify address range. You may be able to pair this with some of the other ELF tools to extract just a specific address range, and then run this tool on that. Alternatively, this dumps in address order so you could dump the entire ELF file and then just look at the address range you want after the fact.
