having issues with using an AVRISP-MKII to burn a bootloader for an ATMEGA328-AU (the same as on the Pro and Pro Mini)

Error:

Code:

avrdude: Expected signature for ATMEGA328P is 1E 95 0F

I have a schema here



any thoughts?

[Reply #1 on:]

'avrdude' checks the signature bytes in the target processor against what it expects, given the processor that you told it about.  So, if the actual processor is a 328-AU and it's expecting a 328P, the signature won't match.  Can you select a different processor from the menu?

i take it i can add a new board to the boards.txt file.
like so

Code:

[new board name].build.mcu=atmega328p

where can i change the mcu listing type. i can't find how to add the AU

Looks like the atmega328 (without the P) isn't in the config file for avrdude. Locate file avrdude.conf, open it in an editor and locate the atmega328p section, which starts like this:

#------------------------------------------------------------
# ATmega328
#------------------------------------------------------------

part
    id              = "m328p";
    desc            = "ATMEGA328P";
     has_debugwire = yes;
     flash_instr   = 0xB6, 0x01, 0x11;
     eeprom_instr  = 0xBD, 0xF2, 0xBD, 0xE1, 0xBB, 0xCF, 0xB4, 0x00,
                0xBE, 0x01, 0xB6, 0x01, 0xBC, 0x00, 0xBB, 0xBF,
                0x99, 0xF9, 0xBB, 0xAF;
    stk500_devcode  = 0x86;
    # avr910_devcode = 0x;
    signature       = 0x1e 0x95 0x0F;

If you change the final signature byte from 0x0F to 0x14 then it should recognise your chip (but not a atmega328p). Or you could try copying the whole atmega328p definition and in the copy change the id, desc and signature byte fields, then use the new id or desc to identify the chip in boards.txt, but I don't know whether this works.

Okay, so turns out i actually have an ATMEGA328-AU-ND not an ATMEGA328P-AU-ND   

any suggestions?

[Reply #5 on:]

everything after the first dash is irrelevant, dc42 still has exactly the answer you need.

[Reply #6 on:]

silly question but where do i find the avrdude.conf on PC

[Reply #7 on:]

I installed the arduino software into C:\arduino-0022. My conf file is C:\arduino-0022\hardware\tools\avr\etc\avrdude.conf.

[Reply #8 on:]

Creating a new entry worked beautifully

Code:

#------------------------------------------------------------
# ATmega328-AU-ND
#------------------------------------------------------------

part
    id              = "m328au";
    desc            = "ATMEGA328-AU-ND";
     has_debugwire = yes;
     flash_instr   = 0xB6, 0x01, 0x11;
     eeprom_instr  = 0xBD, 0xF2, 0xBD, 0xE1, 0xBB, 0xCF, 0xB4, 0x00,
             0xBE, 0x01, 0xB6, 0x01, 0xBC, 0x00, 0xBB, 0xBF,
             0x99, 0xF9, 0xBB, 0xAF;
    stk500_devcode  = 0x86;
    # avr910_devcode = 0x;
    signature       = 0x1e 0x95 0x14;

and then in boards.txt

Code:

.build.mcu=m328au

thanks again for all your helps

Hm, I am attempting to program an ATMEGA-328-PU-ND using an Arduino Duemilanove w/ ArduinoISP loaded onto it. I just added the entries as stated by 32teeth to my avrdude.conf and board.txt file, but I got the following error message when I tried to upload my sketch:

I am using Arduino 0021 on a 32-bit Ubuntu 10.04 installation.

[Reply #10 on:]

Are you sure that avrdude is looking at the correct conf file?  it doesn't look like your edit is in the config that it's reading at all.

The only other nitpick is that 328 is the proper device name, 328AU does not exist.  But that is entirely a cosmetic change and has no relation to your problem.

[Reply #11 on:]

That error looks very odd as if you are missing a part of the .conf file.
Did you add an entire duplicate entry or only the portion i posted?

[Reply #12 on:]

I only added the bit you posted, so maybe thats the problem. I will try duplicating an entire entry and replacing the relevent section with what you posted.

[Reply #13 on:]

I duplicated the entry for ATMEGA328P, then replaced the relevant lines that you posted in avrdude.conf. Then, in boards.txt, I changed the following line:

Code:

atmega328.build.mcu=atmega328p

to

Code:

atmega328.build.mcu=m328au

and now when I try to upload, I get an error saying that the stk500 programmer is not responding.

I'm curious, where do you get the .build.mcu identifier from? At first I thought it was the "id" field of the chip you want from avrdude.conf, but when I search that file for atmega328p (the original identifier), it does not match any 'id' field, only a 'desc' field.

[Reply #14 on:]

When to says the stk500 programmer is not responding, it means your Arduino that you have configured as an ISP. Did you load the ArduinoISP sketch on it, before changing the upload.using line? Did you add the capacitor to disable the auto reset on the Uno?
