As already stated in a previous reply, IAR can generate during build an HEX file
:
you need to ask for a linker extra-output file in Intel-extended format (file
extension will be .a79 in the .exe directory)
BUT
we found that this file does not match exactly what is programmed in the LPC
flash memory with JTAG
This might not be a real issue but, to avoid this difference, we generate the
HEX file the following way :
- we progamm the part with JTAG in debug mode.
- still in Debug mode, we use the memory save option to save the complete flash
in an HEX file.
As I said, this trick might not be required but it works.

Check out the GNU tools that come with IAR 5 (assuming you use this
version). Then check the manuals for the GNU binutils.

Under Project\Options, select the Output Converter category. In the dialog for
this category, check "Generate addtional output". This will enable a choice of
addtional output files to be generated, including Motorola S-record & Intel
hex.

Hi!
I'm new in using IAR IDE and I need to generate a .hex file to
programm my chip(LPC2148) with LPC2000 Flash Utility(LPC210X_ISP.exe).
I observe that the output generated by IAR have elf-gcc extension or
orther.
Can anyone help me?
Thank you!
