In Keil Target options, I had selected the following;

Device - P89C52X2 - Use LX51 extended Linker
Target - I am using code banking with 2 code banks
Output - Generate single hex file Hex 386
Listings -
AX51 -
LX51 Locate - No Classes entries. In SEGMENTS, I had fixed addresses for Interrupt modules and for main().
LX51 Misc -

But, the problem is that the system is not booting and it seems to be like there is no main() detected (or) the XDATA RAM Off-chip is not taken into consideration by Keil.

Please provide me some 8052 project source code links that are using code banking and xdata banking together.
