Dear All,
I wuld like to write a simple project in Assembly for the TMS320C6416 and to be
assembled with the code composer v3.1.
But actually I don't find any template project for assembly or any document
that tells you how to start an assembly project with code composer studio.
Please if any one know how to start an assembly project?? reply to me soon !
Thanks
Thanks,

Try:
1. TMS320C6000 Programmer's Guide [spru198]
2. Also write a simple program [NOT 'hello world' - do not use any
I/O] that adds 2 variables and exits. Setup the project to save the
'asm' file - it might give some insight.
3. There are [or were] some asm examples shipped with some versions of
CCS. There are also some hand coded benchmarks at ti.com.

An easy way to lose the warning is...
Instead of just '.text', you can add the following to the top of your asm file:
.def _c_int00 ;make symbol external
.text
_c_int00: ;use as entry point to make
compiler happy
This warning is a bit stupid for an embedded compiler error to
generate [it is harmless]. 'c_int00' is the default entry point used
by the C compiler [anytime that you generate a C program and load it,
CCS will be pointing to this label].

"No Autoinintialization" is correct - autoinitialization is only for C code.
Good luck on your quest.
