P89V51RD2 code not working.

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.

    "I am also trying to program the P89C61X2BN microcontroller using FlashMagic. But could not connect it,"

    I saw that the OP had written Using ISP Flash Magic Tool it is working... without noticing that someone else had jumped in.

    I haven't been around here for a while but I had a look in and was a bit disappointed to see that your behaviour has regressed somewhat in my absence. Don't you worry, though, we'll soon sort that out.
