Check whether you have done the proper jumper settings for the board.

hello everyone, 

                      i am also trying to dump the code using flash magic, and i have been facing several problems in doing so. I am using usb to serial converter(DB-9 port). Also i am not using any developing board, hence i am not using any reset switch, i simply power up the circuit when asked to reset in isp mode.

                      Firstly i had problems regarding the baud rate(i had selected 9600 as baud rate) and while doing so auto bauding had failed. Then i unchecked DTR to control RST. and now the error that comes is “Unable to communicate(transfer/receiver)”.

 

I have come to a standstill and any help would be highly appreciated.

Thank you.

I’am trying to flash P89V51RD2 controller & i’am using flash magic 7.6 & serial port.

 

when i press start button i’am getting the following error

 

Unable to connect at the specified baud rate. Try reducing the baud rate. Failed to autobaud.

Reset the hardware into ISP mode again.

 

 

I tried using different baud rates, still i’am getting the same error

 

Please help me to solve this.
