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

Try unchecking the DTR/RTS options in the Advanced Configuration. Then click on "Start" and power cycle your device when it tells you to.

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.
