Hello everyone,
i have program and converted that .asm file successfully into .Hex file and file size of .Hex file is 5k and i am using AT89c52 microcontroller. when i am buring the .Hex file into Microcontroller, The uploader software is first erasing then writing the file successfully into Microcontroller But then it is verifying i don't what it is verifying and giving error in verifying. uploader software is showing a message saying "verify error".
now what can i do to solve this problem?

This should be in the microcontroller forum, however, is it possible that the "burn once" bit in your processor got set?
 
Hey MikeMl i did not understant what does that mean. can you please explain what should i do to burn or to remove this problem. please
This controller was burned for the first time and error occured then i thought it may be faulty controller then i replaced the controller and along with that i brought one other AT89c52 microcotroller. the same problem is there for both Ic.

MicroChip's products have a feature called "Code Protection". It is triggered by writing a zero to a configuration bit. Once written, it cannot be undone. Once written, the code can not be read out of the chip using a programmer, therefore cannot be verified. I cant remember if the code can be overwritten. Dunno what yours has.
