Compiling differences between C51 v7.03 and v8.06

Hello!

I have uVision that compiles fine with the C51 v7.03 compiler and the related package, but not complete with the 8.06. I used two different Keil installations. All files are in the same folder.

In the 8.06 I get linker errors like "object does not fit in to pdata page" and "0080H". This looks like the compiler was thinking the PDATA was only 128 bytes, but it is set to 256 bytes in the startup.a51. Any clue what's different in the newer Keil package?

Also there is a warning in 8.06 (which does not show in 7.03) "converting non-pointer to pointer" on this

ptr_xdata = sPtr_obj->Adresse;


while the vars are set like this:

uchar uc_set_obj( uchar pdata *ptr_Set)
{
   uchar i;
   uchar xdata *ptr_xdata;
   struct stOBJADR code *sPtr_obj;

   sPtr_obj=&Obj[*ptr_Set];
   .
   .
   .
   ptr_xdata = sPtr_obj->Adresse;
}


The struct stOBJADR has a member "uint Adresse;"

I can see no wrong use of the pointers. I just want to be sure that the warning does not affect the code to not work correctly.

    If, instead of trying to misunderstand me, you tried to understand (if that is within your mental capacity) we would not have these exchanges.

    I try to understand what you write. If I can understand it, and find it to be wrong, I point it out. Generally I ignore the stuff that is completely indecipherable.
