Hello shaik,

your description isn't as informative as it should be. At least a 
circuit diagram would be helpful.
Also, the so called "hardware condition" for the bootloader is not only 
to pull-down /PSEN while releasing the reset signal, but also have EA 
pulled high. But without circuit diagram it's hard to say...

And, the problem could be related to the oscillator circuit -> have you 
checked if the oscillator is running?

Regards,

Ralf

Do you really mean only selecting the device, or does the communication 
fail when you click on the connect button? (error message something like 
timeout error)

Ralf

Look up the datasheet page 59, there's something on the conditions for 
the bootloader to start.

> how can i check oscillator is running..??
Usually with a oscilloscope. I you don't have access to a oscilloscope, 
you can measure the voltage over the XTAL pins. If ~1/2 of MCU supply 
voltage is measured then the oscillator is running.

Not clear to me:

1. Select the device
2. Select the interface -> RS232 -> A dialog should open where you can 
choose the COM port and baudrate -> then click on "connect"

Did you made these steps?
