DIFFICULTY IN ACCESSING MCU XRAM

Hi! I'm using Philips P89v51RD2FBC microcontroller. I build my project using Keil version 2.0. After compilation, total memory utillization is:
Data: 155.2, Xdata: 327, Const: 2062, Code: 23176

Eventhough there is a free memory space in Data as well as in Xdata(MCU XRAM) memory, still I'm facing problems in accessing variables declared as "far" in MCU XRAM. i.e. the value of these variables get corrupted.

So, kindly help me in solving this problem.

Regards,
Kshama.

you are trying to run before you know how to walk, you are trying to walk before you have learned to crawl. this is a surefire way to break a leg.

WORK THROUGH (I did NOT say 'read') the "Keil getting started guide" and then come back with the questions you may have then.
