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 

[Anonymous]

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.

[Srinivasan]

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..
