.bios section warning, again

Hi Luis --

Can you please double-check your .map file to make sure that you are really using 4.3.8?  See the top of the .map file below for a simple app which has .bios sections.   I don't see this problem in my setup.

Hi karl,

Thanks for your answer, but it looks like I am using them (the code generation tools 4.3.8):

I upgraded both the code generation tools and the BIOS (since I was still using what came with Code Composer 3.1). That meant upgrading from cdb to tcf format using the cdb2tcf.exe tool. What I'm thinking is that the tool left something that is confusing the compiler.

Thanks, I'll try that. Porting is always tricky, so I might just get the example to work and then add my source code files.

The post you pointed me to was the one I had seen before, and of course in that case he was using BIOS 5.31.02, that's why I'm confused.

Anyway, thanks, I'll let you know how it works.

I'm trying to use Code Composer 3.3 (3.3.82.13 if it matters). There is file->new->source file or Project->new, but no wizard gets invoked. So I tried opening one of the example projects under the code composer 3.3 (C:\CCStudio_v3.3\examples\evm5510\csl\dma\dma1_useBios), because it's closest to what I have and want to do. It is a cdb-based project so it goes through the conversion, but it still complains about finding the .bios section. And as is, it does not compile, exits with linker errors.

Next I tried the latency example from the bios directory (C:\CCStudio_v3.3\bios_5_41_10_36\packages\ti\bios\examples\advanced\latency\dsk5510). It still gives me the same warning:

warning: Section ".bios" is found in
   "C:/CCStudio_v3.3/bios_5_41_10_36/packages/ti/bios/lib/bios.a55L<fxn_c.o55L>
   ", this could cause potential compatibility problem. Please use 4.1.x tools
   or update your DSP BIOS

but it compiles and runs fine in the debugger. Unfortunately I don't see examples that include dma/external interrupt usage, that's what I'm interested. Perhaps I should just ignore the warning ...

I think I'll just drop the DSP/BIOS. I don't really need tasks or other BIOS goodies, I think. Just a main and ISR's, so the CSL should be enough. Is there something that I can't really do without the BIOS? It really seems a lot simpler to just use the CSL.

Thanks

If you have a simple project, then you may not need BIOS and we can drop this thread.  

It seems like you still have a problem with pointing to an old c55xx.cdb file or having some other setup problem.  The generated .cmd file should have a --diag_suppress=10286 option which would suppress this warning.   This --diag_suppress is added to the .cmd file from c55xx.cdb file.  The fact that you are getting this warning tells me that you don't have the right c55xx.cdb file.
