Hello Everyone,

I have started to work on P89V51RD2. To burn hex , I am using Flash Magic 3.71.245 .

I am following the steps given below:
1)Settings in P89V51RD2:
COM PORT: COM2 (I hve only this port)
Baud Rate: 9600
Device: P89V51RD2
Interface: None (ISP)

2)Option>Advanced option> Hardware Configuration> unchacked "Use DTR to control RST" > unchecked "Assert DTR and RTS while COM port open"

3)Pressing switches connected at Pin 9(RST) and Pin29(PSEN) .

4) Browse the .hex file

5) select "Start"

6) after getting Messege : "Reset the device into ISP mode", Releasing switch at Pin 9 (RST)

7)Releasing switch at Pin 29 (PSEN)

8) After some time , I get Messege: "Erasing Device... "

9) After a long time, I get Messege: "Programming.."

10) After a few second, I get Messege: "Unable to communicate (transmit / receive)"

Thus, currently It is not working. Please any one suggest me some correct way to get proper result.

Please, reply soon.
Thank you
