Respected All,

I am using P89V51RD2 for making a project. The project includes the data to be written in the EEPROM of the microcontroller.

Could you please guide me how can I write in FLASH MEMORY using the FLASH MAGIC.

Is it required to invoke the BOOT LAODER for doing this.

I dont have the parallel programmer.

Hello  there !

Everything was cool, I could Communicate with hyper terminal and test my programs.



The next assignment I bought from the dealer is with the following
description and now  I can not establish the communication with the
hyper terminal

What could be the reason ?

I was using P89C51RD2HBP, It was working OK. Recently I changed over to
P89V51 RD2BN.

After selecting P89VRD2 device, baud rate 9600, (Selection of Oscillator Frequency window does not appear), the hex file is downloaded
successfully. When I interface with the periphrials it does not work at all,
whereas I tried with P89C51RD2HBP, with 11.0592 Hz, it works without any problem.

Please help me to get rid of this problem. Is P89V51RD2BN is deifferent ?

Regards
