    i know we have to use flash magic to load a hex file into microcontroller,
    i have a designed a microcontroller kit,everything is right as far as i know,even the professors say the circuit is right,i have checked voltages at every required point to see if the microcontroller is getting the voltage or not.....everything is checked.but the problem is,no program would load in my p89v51rd2....
    i really need some help.
    i am using max232 to drive the controller and rs232 as serial communications....
    thanks in advance.

    Without a schematic and some photos of your circuit, there is not much we can do to help you.

    I'm sure I had a switch on EA pin or something so when it resets it goes into bootloader mode...
