hi
now the programming is done on the board and booting too
but a problem is still that when i remove the MON-08 CONEECTION from computer then booting is stop .
i think this is due to any fault in circuit of RESET,OSCILLATOR,IRQ
i have used
RESET------100K FROM VDDTO 28 PIN
IRQ--------10K FROM VDD TO 1PIN
CRYSTAL IS 4MHZ BOTH end is pull-down by 22pf capacitor and legs are connected by 440k resistance.........
where is fault ?
