Hi
I am doing project based on Philips P89v51RD2FN.
i did the 5 steps procedure to dump the Hex code into Device.
But i am getting error ,whem i am clicking the step 5----statr.
It is showing
Unable to connect at the specified baud rate. Try reducing the baud rate.Reset the hardware into ISP mode again
i had done the following steps in Flash magic
Step 1:
com port --- com 1
Baud rate ---- 2400
Device ---- 89V51RD2
Interface ---- ISP(none)
it disabled the oscillator frequency
Step 2:
I had marked erase bolcks used by Hex file
Step 3:
I had loaded my Hex file
Step 4:
I had marked verify after programming, set security bit 1,Gen block Checkgums
Finally i clicked start button. that timeit is giving the above mentioned errors
Please help me to avoid the error and dump program to device
Plz.....Plz help me
Try unchecking the DTR/RTS options in the Advanced Configuration. Then click on "Start" and power cycle your device when it tells you to.

I did whatyou recommened ,but now also it is giving error like
Reset the device into ISP mode.
I reset the device in that mode .
Still also it is giving the error.
Thanks

Try raising the baudrate to 9600. Put a scope on the TxD and RxD pins and see if a 'U' is going into the device and a 'U' is coming out. Compare the timing of this with the reset signal on the reset pin.

I have the same problem.
It always tells me that " Unable to connect specified baud rate, Try to reduce baud rate , Reset hardware to ISP mode again."
but I don't know what's wrong with it.
My following steps are the same with Mr. Yuvaraj.
I also set the baud rate to 2400, but it always want me to reduce the baud rate =.=
Please teach me how to solve this problem, thanks.
I solve the problem what I have mentioned.
("Options -> Advanced options -> Hardware Config -> unselect "Assert DTR and RST while COM port open")
But there is another problem.
In the step 2, it said
"device signature can't be read.Unable to commuicate(transmit/receive). Assesing a device using the wrong protocol can render the device unusable",
but if I skip, I still can continue earsing.
But in step 3, it said "Unable to connect(transmit/receive)" , and then failed.
What's happened to it? Please teach me how to solve this problem, thanks.
