    Did you provide the AT89S52 with proper crystal and power supply?

    The problem should be at the AT89s52 side, check the clock and power supply.

    You need to check the power supply, Crystal oscillator and reset line of the microcontroller.

    sometimes this problem can be solve by removing the RC reset circuit ; I mean just ground the reset pin using a 4.7k resistor don't use any capacitor
    but for power on reset this capacitor is necessary so the best way i think is use a 0.1 uf capacitor
