    for the flash magic to transfer u need to select proper device that is 89v51rd2

    then ur com port that is ur printer port mostly it will be com1

    then ur baud rate make it 2400

    interface isp(none)

    after done with these 4 options

    select erase all flash option

    and select verify after programmin

    u will be able to transfer the file to ur microcontroller

    i got it

    the problem is not with the mc

    the problm is with the rs232 cable  used for interfacing

    i used 9 pin cable  then it worked

    when i pressed the reset button the popup box just disappeared and code was dumped into mc

    so i prefer 9 pin cable insted of rs232

    hellow every one

     

    at first i got the same problem

     

    the main problem is if you are using a new version of flash magic and the vegarobokit

    8051 board.

    the crystal frequency in the board is

    11.0592MHz

    so enter this frequency value in the respected column of flash magic.

     

    if you are using a USB to RS232 cable

    then check that your system is supporting

    the drivers are not.(W7 wont support)

    if you are using DB9 serial port

    then there is no need of drivers

     

    after powering on the 8051 board

    connect it to PC through the cable

    then right click on MY COMPUTER

    then click on devise manager

    it will display all the communication ports.then disconnect the cable and re connect it.find the comport  (com1 or com2….etc)

    select that perticular comport on flashmagic.

    then try programming it.

    it will work

    if not there will be some problem with max232 ic.check its capacitors

    in flash magic check in option half duplex mode. and if everything is ok then first press the reset switch on your development board and when the msg of reset isp pops up at that time release the switch.

    I used 9pin serial port.

    After resetting the device in to ISP mode i am getting unable to connect (Transfer/Receive).

    Any one can help me in solving the issue.

    In 9 pin serial port i connected only Tx, Rx & Gnd.

    Whether i need to connect any other pin..
