Problem with mixing assembler and C

I don't think you need the assembly, try this...

void (*entry)(void) = ( void (*)(void) )2147483648;

entry( );

The first line defines a pointer to a function you wish to call and then assigns the value to it after casting the value to a pointer to a function of the proper type.  Then all you need to do is call the function using the pointer to the function just like any other function call.

If you want to pass the value to the function then you will need to redifine the pointer declaration like this

void (*entry)(unsigned long) = ( void (*)(unsigned long) )2147483648;

entry( 0x80000000 );

If you don't want to make the assignment at declaration time, you can always defer it to later like this

entry = ( void (*)(void) )2147483648;

or

entry = ( void (*)(unsigned long) )2147483648;

If you would like to make your code a little easier to read, use a typedef like this

typedef void (*func_t)(void);

func_t entry;

entry = (func_t) 2147483648;

entry();

a similar apporach can be used for the function which takes a parameter.

At least that's what your code and your comments look like you are attempting to accomplish.  If not, clarify a bit more and I'll try again.
