Dear Readers,

i am using a Motor Control kit with the AURIX TC234 that Comes with it's own demo Code and i am a rookie with AURIX microcontrollers.
When i build the Code in eclipse i always get the same error:

astc E118: ["2_Out/Tasking/0_Src/4_McHal/Tricore/Cpu/CStart/IfxCpu_CStart0.src" 10] expected
astc W201: ["2_Out/Tasking/0_Src/4_McHal/Tricore/Cpu/CStart/IfxCpu_CStart0.src" 283] local symbol "_SMALL_DATA_" not defined in this module; made external

make[1]: *** [2_Out/Tasking/0_Src/4_McHal/Tricore/Cpu/CStart/IfxCpu_CStart0.o] Error 1
make[1]: *** Waiting for unfinished jobs....

i am using the TASKING Compiler Version 6.2r2.
i want to know what can i do to solve this Problem.

I remember a similar case from several years ago. Although I can't be sure, these are the steps to find out. Goto the following iLLD folder (path may be off by the way):

\0_Src\4_McHal\Tricore\Compilers

And open CompilerTasking.h. Next check the definition of IFXCOMPILER_COMMON_LINKER_SYMBOLS. If it reads:

asm("\t .extern (DATA) _SMALL_DATA_, _LITERAL_DATA_, _A8_DATA_, _A9_DATA_");

Then you must remove the (DATA) cast because as far as I know this is invalid assembler syntax for TASKING. So instead it must be substituted with the follow valid equivalent:

asm("\t .extern _SMALL_DATA_, _LITERAL_DATA_, _A8_DATA_, _A9_DATA_");

Let me know how this works out.
