Not able to burn the hex file into LPC2148

Hello All,

I am Amit.

Trying to burn the hex file into LPC2148 by using flash magic 5.70.2079

But I am getting error, "Operation Failed. Failed to autobaud - step 1."

I have tried a lot by changing setting in flash magic's options -> advance option->

Right now I kept like this only.... tick to "assert DTR and RTS while COM port open"

but not getting any clue that why my hex file is not getting burned.

Plz guide me.

thanx in advance.
