I am using P89V51RD2BN(40 Pin) IC and KEIL Compiler to generate .hex file. I have compiled a simple code to generate a square wave on pin no. 5 of P3 port(P3^5).
I m using Advantech Lab Tool-48UXP External programmer to program P89V51RD2.
When I Burn the code in Atmel 89C51 square wave is generated on pin no. 5 of P3 port(P3^5), but the same code when burn for P89V51RD2BN, it does not work.
We have included P89V51RD2.h as a header file to main source code provided on KEIL website.
P89V51RD2 processor specific STARTUP.A51 is created using KEIL µVision3 software and .hex file is created using the same software.
Please tell why such a simple code is not working in P89V51RD2??
Am I missing any steps while generating .hex file.
Have you carefully checked all the details of the "Atmel 89C51" Datasheet against all the details of the "P89V51RD2BN" Datasheet?
If it "works" on one but not the other, then you must be relying on something that happens to hold for one but not the other
"We have included P89V51RD2.h ... P89V51RD2 processor specific STARTUP.A51"
Those are indeed necessary - but not sufficient.
but I totally agree with Andy.
since the P89V's are fairly recent I'd ask
does your programmer have a selection for this chip and are you using it.
there has been threads in this forum before where the above question was answered with "no, but I thought I could use"

Dear Sir,
Thank u for ur response.
We have already verified both Datasheet. of P89V51RD2 and Atmels 89C51.
There is no such difference between that.. still we are trying for the same. Still if u get any solution please let us know...
Thanks for reply....
Hello....
We have found solution for the problem which we had posted......
Earlier, We have used Universal Programmer Toolkit for programming P89V51RD2 IC.
But due to some reason we don't able to find expected result.
Now instead of using that TOOLKIT we are using Flash Magic Software for programming P89V51RD2.
Flash Magic-- In System Programming(ISP) using COM port.
Now it is working fine.....
Thanks

I asked "does your programmer have a selection for this chip and are you using it."
you never responded (well some babble about datasheets)
the programming algorithm is (fortunately) not in the datasheets any more.
if you tried to program a chip in a parallel programmer that did not have a setting for the exact chip it would not work
Hello Erik,
Thank u very much......
In Programmer we have option for selecting particular Chip.
But due to sm reason it was not working.

what is 'sm'
Erik,
He's probably just borrowed the dodgy keyboard you frequently appear to use ;)
Hey Erik,
sm means some...... we have not found any reason yet but there might be problems with Universal Programmer.
Using ISP Flash Magic Tool it is working...
Thanks...
Does it?
IS it really so hard for you to type "some", so that your message will be clear and unambiguous and immediately understandable to everyone - without having to guess whether it's a typo, or some "cute" abbreviation, or whatever...?
You can make it easy for people to help you, or...

Hi, I think you successfully able to program the microcontroller. I am also trying to program the P89C61X2BN microcontroller using FlashMagic. But could not connect it, as it is showing error related to autobaud and also some error related to could not connect,reset into ISP mode. I need some help to resolve this. Could you please help me in this regard?
Regards Rajesh
using FlashMagic why do you ask at the Keil forum instead of the FlashMagic forum?
