I use no Arduino just trying to program a simple ATMega32 using USBASP. Getting this message:

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

avrdude done.  Thank you.

Explanation:

I use an AVR development board with 8.00:

AVR developement board

To make the AVR model label more clear, I have made this photo as well (photo)

To program the microcontroller, I use a USBASP. The crystal of the programmer is 12.0 MHz (though might not be relevant).

USBASP programmer

I installed Avrdude on ubuntu and wrote the following program:

// main.c

#define F_CPU 8000000UL

#include <avr/io.h>
#include <util/delay.h>

int main(void) {

 DDRD = 255;
 PORTD=255;

 DDRC = 255;

 while(1){

 PORTC=255;
 _delay_ms(200);

 PORTC=0;
 _delay_ms(200);
 }

 return 0;
}

Then compiled and made hex file:

avr-gcc -w -Os -DF_CPU=8000000UL -mmcu=atmega32 -c -o main.o main.c
avr-gcc -w -mmcu=atmega32 main.o -o main
avr-objcopy -O ihex -R .eeprom main main.hex

Till now main.hex file is created successfully.

Then, trying to load it into microcontroller:

sudo avrdude -p m32 -c usbasp -B 8 -v -e -u -U flash:w:main.hex

And the output is disappointing. I mean the last part:

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

avrdude done.  Thank you.

Here is the way I have connected the microcontroller while downloading the hex file:

Downloading hex file

When I check the communication, it seems to be alright:

sudo avrdude -p m32 -c usbasp -t

The response:

avrdude: warning: cannot set sck period. please check for usbasp firmware update.
avrdude: AVR device initialized and ready to accept instructions

avrdude> 

So what is wrong? What to do?


It seems nothing is programmed. I checked it with a 5VDC adaptor (photo) and a breadboard with LED and capacitor. Connecting LED to VCC turns it on (photo) which shows LED is working. Connecting to any pin of port D does not turn on the LED (photo) connecting to some pins of port C turn on the LED (photo) and some don't (photo). But there is no blink. Note that I am using a virgin ATMega32 chip.


Update

Inspired from this website (btw, I dont know German!) and a few others, finally I used the following command:

sudo avrdude -p m32 -c usbasp -v -b 19200 -B5 -e -U flash:w:main.hex -U lfuse:w:0xe4:m -U hfuse:w:0x99:m

avrdude done.  Thank you.

Seems it works!!!

Now, all pins on portD turn on the LED bright and pin C0, C1, C6 and C7 blink bright while C2, C3, C5 give dim but constant light to LED and C4 does not turn on the LED at all.

Though, I am very happy of writing something into the chip, could someone explain what has happened?

It seems the problem was in baud rate. "-b 19200" was the solution.

A promt was in line: "avrdude: warning: cannot set sck period. please check for usbasp firmware update."

\$\endgroup\$
  • \$\begingroup\$ The baud rate setting does nothing with USBasp, as far as I am aware. The USBasp is a usb device, and does not use a usb to serial converter internally. The same applies to -B, which sets the bitrate but works with the Atmel JTAG ICE only. For lowering the data rate with a USBasp, there should be a jumper or solder pad that you need to short out if the target clock frequency is too low (< ~2MHz). \$\endgroup\$ – jms Jun 24 '15 at 15:05

I had the same problem and changing the lfuse to E4 fixed it! I think 1Mhz may be too slow for the programmer and setting to 8Mhz internal fixes it.
