TMS570 Flash API problem

Renjith George

Hello,

I started working on the TMS USB development kit. I was able to initialise the microcontroller and flash LED via the ports.

When i tried to use some Flash API as SPNA117A–May 2010 document i encounter some error

file "../pf035a_api_eabi.lib<compact.obj>" was built without VFP coprocessor support while a previously seen file was; combining incompatible files

So i modified Project->Properties->C/C++ Build-> Runtime Model Options->Floating point support from VFPv3D16 to "Blank" (No selection) .

Then i get another error

file "C:/Program Files/Texas Instruments/ccsv4/tools/compiler/TMS470 Code Generation Tools 4.6.6/lib/rtsv7R4_T_be_v3D16_eabi.lib<copy_decompress_none.obj>" was built with VFP coprocessor support while a previously seen file was not; combining incompatible files.

Can anyone please provide some solution to sort this out ?

Thanks,

Renjith George

Renjith, Your first error was you were including the non-floating point version of the Flash API. For a floating point project, you need to include pf035a_api_eabi_vfp.lib. The second error you were getting was your project was trying to still link in the floating point version of the Runtime library instead of the non-floating point library rtsv7R4_T_be_eabi.lib. The CCS codegen tools will not allow you to link file compile with floating point support to files that were compiled without floating point support.

Dear John,

Thanks for your inputs. We changed the path of linker include files

Properties-> C/C++Build ->TMS470 Linker ->File search path to point to the location of "rtsv7R4_T_be_eabi.lib" and it worked fine.

Earlier it was pointing to the path of "rtsv7R4_T_be_v3D16_eabi.lib"

Thanks,

Renjith George

Hi,

What is the significance of the 'T' or 'A' within the library name?

Thanks, Tony.

T stands for Thumb mode and A stands for ARM mode.
