Way to Download DSP .out file without Code Composer

Started by Ben Nguyen March 15, 2004
Im looking for a way to just download the dsp .out file from a pc to
the dsp via the JTAG emulator pod.  Once downloaded, the code can flash
itself into flash memory.

This is for the production people, which dont have the need to compile, 
debug, simulate, or anything else... they just need to download the executable
to the target.

The only software that I know can do this (Code Composer)
seems like an expensive solution.

Is there any 3rd party vendor that just downloads the .out file?
Is there a limited 'programming' version of Code Composer?
Anyone else run into this issue before?

Ben:

I could be wrong (its been a long time), but I think a .out file is just a
COFF file (common object file format). Thus, you just need to read about the
COFF format, and write your own downloader (just a matter of parsing address
and data), or obtain a COFF downloader for your target.

Check out Spectrum Digital emulator package.  They make mention of their "
"SDFlash" Programming Utility from Spectrum Digital "  maybe this will do
what your looking for:

We flash without the emulator via a serial port, but requires the flash to
be initially programmed (either before sodering to the board or via the
emulator) with a small loader applet.
