CMSIS Library build error in CCS v6 for Tiva C Series Microcontrollers

LAXMI KANT TIWARI said:

I have followed user guide given at http://www.ti.com/lit/an/spma041d/spma041d.pdf as well as some other thread discussed on TM4C forum after getting these errors but did not get solution. I have tried with ARM compiler 5.1.6 as well as 5.1.9.

I had the same errors when attempted to build CMSIS-SP-00300-r4p2-00rel0 using TI ARM compiler v5.1.9 following the instructions in spma041d. The errors seems to be a conflict between the definition of _INLINE in the CMSIS core_cme4.h include file the the TI ARM compiler linkage.h include file.

As an initial work-around I added predefined symbols for _LINKAGE, _CODE_ACCESS="" and _DATA_ACCESS="" which allowed the project to compile with TI ARM compiler v5.1.9:

These predefined symbols allow the run time library to compile without bringing in the definitions from linkage.h which cause the conflict over _INLINE. Need to determine if this is the correct "fix.

Hello All,

Thanks for the quick response. It can be corrected by updating linkage.h

replace the line
#define __INLINE static __inline

with
#define __INLINE inline

UPDATE: Instead of modifying the linkage.h, attached is the updated core_cm4.h (to replace the core_cm4.h in the CMSIS\Include directory. The same shall be pushed into the zip package and App Note updated in the next couple of weeks)

I am also getting the following warnings about missing definitions for intrinsic functions:

Description Resource Path Location Type
function "__ROR" declared implicitly arm_power_q7.c /splib-cm4f/StatisticsFunctions line 99 C/C++ Problem
function "__SXTB16" declared implicitly arm_power_q7.c /splib-cm4f/StatisticsFunctions line 99 C/C++ Problem
function "__SXTB16" declared implicitly arm_dot_prod_q7.c /splib-cm4f/BasicMathFunctions line 101 C/C++ Problem
function "__ROR" declared implicitly arm_dot_prod_q7.c /splib-cm4f/BasicMathFunctions line 101 C/C++ Problem

function "__ROR" declared implicitly arm_q7_to_q31.c /splib-cm4f/SupportFunctions line 97 C/C++ Problem

To define these intrinsic functions, suggest the following needs to be added to cmsis_ccs.h:

#define __ROR          __ror
#define __SXTB16(src1)     _sxtb16(src1,0) /* The TI ARM compiler rotamt (2nd) argument set to zero, as not in the ARM compiler intrinsic */
