I am using asm56300.exe to compile. So I have the .cld
file (COFF format).
I want to save the program in a i2c serial eeprom in
order to make the DSP's bootstrap program to load it.
How do I go about creating the memory image? It would
be easy if I had the program in s-record format, is
there a way to convert the .cld file to s-record
format? I've heard about the srec.exe program for
doing that but I couldn't find it.

Below is the link to a program to create a memory
image from a s-record file:

Subject: Re: Bootloader for 56364

If you are using the Tasking C/C++ Tools, they have an example for you
to use as a starting point. The sample shows how to use the bootstrap
loader in ROM to load a secondary and ternary bootloader to boot your
program from flash memory. You will need to modify it further if you
are booting from, say, the SCI port. You can find it in your Tasking
installation under {InstallFolder}\examples\bootrom.

On a related note, I'm wondering if anyone has any info on reading the
IEEE 695 format file output from the Tasking tools. When I developed
a flash loader a few years back, I had to use Tasking's utilities
(byte_sel and order) to create a hex file. It would have been more
convenient to operate on the .abs file directly, I think. Anyone
done this before? --- In , dbaudiopro <dbaudiopro@y...> wrote:
