coff2c does not generate source code from a COFF file and is not a step in that
direction. It extracts COFF sections -- executable code (.text section), .const,
.cinit, and any other other initialized sections -- and stores in a standard .h
file. There is some C code that goes along with it that you can use to load the
sections into a TI DSP at run-time; i.e. before releasing Reset.

It's basically a free version of TI's hex6x.exe and hex500.exe programs -- they
functionally accomplish the same thing.

Here is a page with an example of using coff2c:

The above page describes how to load a DSP executable from an ARM core for dual-core
TI devices, for example C5471, various DM2x, DM2x, and DM6x, devices and OMAP 1510,
5910 and other OMAP devices.

Jeff,

Thanks for your reply. But what I want is not make .h file from coff file, I
want to make a .h file back coff file. So I want to know how COFF2C extract
the coff file to a .h file. Is there any detail document about that?
