CCSv4 and FPU support for F28335

Hi there,

I am using CCSv4 and F28335. What I would like is to use the function described in http://focus.ti.com/lit/ug/sprueo2a/sprueo2a.pdf (TMS320X28x Floating Point Unit and Instruction Set).

What I try to do is simply use the F32TOUI16 function.

Unfortunately it says

_F32TOUI16R ./main.obj

 

error: unresolved symbols remain

I have checked and the

-l"rts2800_fpu32.lib"

option is correctly called and fpu32 support is activated and sent correctly to the compiler.

 

 

"C:/Program Files/Texas Instruments/ccsv4/tools/compiler/c2000/bin/cl2000" --

 

silicon_version=28 -g --include_path="C:/Program Files/Texas Instruments/ccsv4/tools/compiler/c2000/include" --diag_warning=225 --sat_reassoc=off --large_memory_model --fp_reassoc=off --float_support=fpu32 $(GEN_OPTS_QUOTED) --preproc_with_compile --preproc_dependency="main.pp" $(subst #,$(wildcard $(subst $(SPACE),\$(SPACE),$<)),"#")

so I don't know what to do.

What shall I add to my project so that I can use these function.
