Hello Ernst,
I've just tried to declare the pointer as a data pointer following your
instructions and this worked out.
Thank you very much for your support.
Now I will try to transfer the solution to the more complex application. I
will try to update the list in case something else comes out.
PS.: I had already noticed in gptrput1.c that the code and the eeprom cases
were not implemented yet, but the data case was there. I just didn't realize
it would use some other code if I declared the pointer as a data pointer.
Thanks again,
Guerra

Could you try with:
void main(void)
{
unsigned char c = 0x34;
data unsigned char *p;
// ^^^^^
p = &c;
*p = 0x12;
}
"data" here tells the compiler your pointer will always be used to point
into
RAM, never Flash/EEPROM/xmem/whatever, so it can optimize the gptrput call
away and directly work with the pointer.
It's always good practice to declare your pointers like that, unless you
really need a generic pointer.
Still, this doesn't fix the original problem, but if the result is still
wrong
with a "data" pointer, the problem most likely lies elsewhere.
