USBTinyISP: Wrong signature with Arduino Uno

[gagou7]

Hi all,

I recently purchased an USBTinyISP kit and make it.

Now I'm trying to use it with my arduino Uno board and I would like to burn the bootloader. So, when I try to burn the booloader, the IDE give me this:

Code: Select all

avrdude: Expected signature for ATMEGA328P is 1E 95 0F
         Double check chip, or use -F to override this check.

And if I use avrdude directly from the command line, I get this:

Code: Select all

# sudo avrdude -c usbtiny -p m32

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.01s

avrdude: Device signature = 0x1e9389
avrdude: Expected signature for ATMEGA32 is 1E 95 02
         Double check chip, or use -F to override this check.

avrdude done.  Thank you.

I checked my solders (visual and with an ohmmeter). The green led is on when I connect the USBTinyISP to my computer. The red led blinks one time when I try to burn. My arduino board is an Uno board and the chip name is "ATMEGA328P-PU". I tried both arduino+avrdude from Debian repository and from the official Linux release on the Arduino website.

Does someone have an idea?

Thank's in advance.

you aren't using avrdude properly

we suggest following the mini tutorial on how to burn the bootloader using the IDE, it will cause you fewer problems

Like I already said, I have an error with a "Wrong signature" with the IDE as well. The "tutorial" of the arduino website doesn't seems to be very helpful.

I just launched the IDE as root (to avoid a "Operation not permitted" error when trying to burn), selected the "Arduino Uno" board, then selected the "USBTinyISP Programmer" and then finally Burn Bootloader.

But always this "Wrong signature" error...

Thank you for your help !

1e9389 is the signature for the 8U2 chip. Are you connecting to the right isp header?

Code: Select all

# sudo avrdude -c usbtiny -p m32



That should be avrdude -cusbtiny -pm328p

Also, you are connected to the wrong ICSP connector. The one you want is the 6 pin block near the end of the big chip.

... You're right, I'm sorry, I connected to the wrong ICSP connector...

Resolved !
