Problem in burning program on atmega32 microcontroller

[Rajat Garg]

I am working on autonomous robots and i have written 3-4 programs in basic language using BASCOM... After compilation it generated hex file but when i try to burn my program using avrdude gui software it shows following error..

avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATMEGA32 is 1E 95 02

after that it shows dat code is written on chip but actuaaly it is nt so... when it tries to verify it shows following error..

avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0000
0x0c != 0x00
avrdude: verification error; content mismatch

avrdude done. thank you..

after this when i try to execute my program in my robot it fails to do so... Please help...

Thank you...

I tried google also where i got following solutions...

1. Check to make sure your ISP cable is connected correctly. The Device signature = 0x000000 usually indicates the programmer cannot talk to the micro controller
2. Set it slow ISP clock

I have connected my ISP cable correctly bt i couldn't understand how to slow down the ISP clock... :|:>

Read in the avrdude documentation how to slow down the ISP clock.

Which programmer are you using for downloading your hex file into atmega32 ?? I don't know about other programmers but if you are using usbasp then your pin 25 must be grounded .. this slows down ISP clock

Thanks a lot sir... I will try this also... but the problem has already been solved...
