code works in simulation not on chip

hi, my first project on uvision but im having trouble making it work. so I'm making a simple POV toy (leds flash and moving it side to side you see a message) using a Atmel AT89S52 microcontroller, with 8 leds connected to its port 2.

i know my programmer and board is working because i made a simple program to toggle leds in port 2 and it work fine.

programmer i using is based on this:

im using the latest version of the software and I added leds on it to see if programs work.
