TMS Compiler v4.9.2

I am using TMS Compiler v4.9.2 for TMS 570 device .

In one file i have function declared as

void func(U32 const *const data);

and in the function call am passing a different data type "sum" and typecasting it to U32 *

func( (U32 *) &sum);

When i tried to compile the above line of code i get compilation error as follows

line 209: error #169-D: argument of type "U32 *" is incompatible with parameter of type "const U32*const"

I compiled the same code on a different compiler (also the micro controller is different and not TI one) it compiles ? May i know which one is correct here ?

To clarify more the function prototype is

void func(COMMAND_TYPE const *const data);

where
typedef U8 COMMAND_TYPE[COMMAND_LENGTH];

and in the function call am passing func( (COMMAND_TYPE *) &sum);

When i tried typecasting func( (const COMMAND_TYPE *) &sum); the compiler passed with no errors.

Hi Omprasad,

Sorry I don't know the answer to this. Also I think it depends on U8 and U32 which themselves are probably in header files.

If you have compiler trouble - there is a compiler forum e2e.ti.com/.../

But this seems to be a generic C programming issue nothing compiler specific - so you might start w. a C language reference.

This forum is mainly for technical support specific to Hercules.
