Floating point values not working on MPC5554

[tkm_moog]

Hi,

I am using Code warrior version..... CodeWarrior for MPC55xx V2.2

Target board : MPC5554EVB (PowerPC), (i dont know whether float hard is supported on this board or not?)

I have created a project with these libraries and support files. Also i am using fp hard for this but its not reading the float values it hangs there in runtime...

 "${CWFOLDER}/PowerPC_EABI_Support/Runtime/Lib/Runtime.PPCEABI.S.UC.a "; 
 "${CWFOLDER}/PowerPC_EABI_Support/MSL/MSL_C/PPC_EABI/Lib/MSL_C.PPCEABI.bare.S.UC.a ";

can anybody tell me anything needs to set for fp hard,

I had tried with these libraries also i am building the project from the command line options

"${CWFOLDER}/PowerPC_EABI_Support/Runtime/Lib/Runtime.PPCEABI.E.UC.a "; 
"${CWFOLDER}/PowerPC_EABI_Support/MSL/MSL_C/PPC_EABI/Lib/MSL_C.PPCEABI.bare.E.UC.a ";

If i use fp soft it gives errors: 

thanks in advance

Hello

According to the "MPC5553/5554 Microcontroller Reference Manual", floating point operation are performed

using SPE on MPC5554.

So Inside of EPPC Processor you need to set Floating point format to SPFP and to link with the appropriate

library.

I would recommend you to create a new project using the project wizard and specify you want to use "SPE-EFPU" as floating point format That should set up your project appropriately.

I did check with V2.3 installation. The wizard only allow you to select a valid floating point format (None, Software or SPE-EFPU).

So in any case I would highly recommend using the wizard to create the project.
