problem with XDATA

Somebody please don't nag.

You haven't shown enough code.

Does your function printlcd() expect a pointer to xdata text or exactly what pointer type does it expect?

If you think your LCD code is secret, or too much noise to present: Create a small sample without the LCD code then - for example a dummy printlcd() function that computes the length and checksum of the string it receives. If your real printlcd() function fails with xdata, then such a dummy function should also fail. In this case, we can't see how your printlcd() function is declared, or how it uses the pointer it receives as a parameter.

Have you separated the two cases where you have the pointer stored in xdata, and when it points to text stored in xdata?

Hi Per Westermark!

my printlcd code:

void printlcd(unsigned char *str)
{ while(*str) //till string ends write(*str++,1); //send characters one by one
}
