Trouble uploading to ATtiny 2313a

As the topic name suggests i am having some difficulty with uploading to an ATtiny23213a.
The plan is top build an alarm clock (my current one is dying on me) and i have a couple of 2313’s lying around, and they would suit the project quite well. Now i have only really used ATtiny 13’s so far, but i thought the process is rather similar (just the ground pin is in a different spot)
But every time i hit the 'upload using programmer i get a long list of device id’s i think is what they are, as an error message.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

But when i switched the board to 4313 i got the ‘Yikes wrong device ID’ as expected.
I’ve tried with 2 different chip’s with the same result.
Any thoughts ?

Do you use a custom boards.txt file?

It looks like the IDE is passing the MCU ID “attiny2313a” to avrdude, and avrdude doesn’t recognise that. If you can change this to “ATtiny2313”, then avrdude should recognise correctly.

Hmmm OK, I managed to upload using a different core
this one
but that is interesting,
Yeah i think i got it to work by doing ‘show verbose output during upload’
Copying the avrdude command command gave me :

C:\Users\deva_\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino18/bin/avrdude -CC:\Users\deva_\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino18/etc/avrdude.conf -v -V -pattiny2313a -cstk500v1 -PCOM3 -b19200 -Uflash:w:C:\Users\deva_\AppData\Local\Temp\arduino_build_345956/AlarmClock.ino.hex:i 

and all the errors of course.
then i removed the ‘a’ from


did an ‘export compiled binary’ and replaced the file location with the resulting .ino.hex file
so then it looked like this

C:\Users\deva_\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino18/bin/avrdude -CC:\Users\deva_\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino18/etc/avrdude.conf -v -V -pattiny2313 -cstk500v1 -PCOM3 -b19200 -Uflash:w:C:\Data\Arduino\Sketches\ATtiny\AlarmClockAlarmClock.ino.hex:i

Then it complained that the access was denied to the com port, but closing all instances of the IDE and trying again, I succeeded.
Great thanks !!

Now where is that particular name ‘attiny2313a’ stored ? somewhere in the core i guess…
or where is the ‘attiny2313’ stored ? Is that in the ‘avrdude.conf’ file ?

I should probably just report it as a bug.
Anyway many thanks, i have a work around and some more investigating to do.

OK for now i just copied the whole definition of the ‘ATtiny2313’ in the avrdude.conf file
and added an ‘a’ for one instance to both the ‘id’ & ‘desc’ and now it works (until i update the IDE i guess)

# ATtiny2313a

     id            = "t2313a";
     desc          = "ATtiny2313a";
     has_debugwire = yes;

Still it would be better if the core provided the proper description. Next step.

I’m running IDE 1.8.13 and my boards.txt file doesn’t mention any of the ATTiny series and a search of the whole Arduino sub-folders didn’t find anything meaningful either.

I’m guessing that you downloaded a “core” that has the ATTiny2313a in it. I think I put my cores into the MySketchbook\hardware folder but I can’t be sure.

There will be a boards.txt file associated with the core that has the 2313a in it. There’s probably a line in the text file like: .build.mcu=attiny2313a - that’s where the bit comes from for avrdude.

According to Microchip, there’s no practical difference between the 2313 and the 2313a so dropping the ‘a’ should be ok.

I don’t know much about avrdude.conf to go poking around in it and copy the attiny2313 section and add the ‘a’ variant.

I suppose it’d be easiest to find that boards.txt file and remove the ‘a’ from the build.mcu line.

Of course I could be completely wrong, in which case somebody wiser will jump in and provide the correct solution.

Yep correcting the name in the boards.txt file works as well. I undid the changes to avrdude.conf to verify.
All that remains is the bug report on github. Thanks again.

Which core were you using (the one that’s broken)?

SpenceKonde ATTinyCore v 1.5.2 (i was on 1.4.x but updated when i had an issue, but that didn’t fix anything)

The problem is that the core is using the wrong version of avrdude.conf. It’s supposed to be using the one that I package with the core. But it appears to be instead using the one that the IDE comes with. I am not sure why this is, and it’s not the one that gets used when I call it. I get

C:\arduino-1.8.13-portable\portable\packages\arduino\tools\avrdude\6.3.0-arduino18/bin/avrdude -CC:\arduino-1.8.13-portable\portable\packages\ATTinyCore\hardware\avr\1.5.0/avrdude.conf -v -pattiny2313a -cstk500v1 -PCOM11 -b19200 -Uflash:w:C:\Users\Spence\AppData\Local\Temp\arduino_build_579291/sketch_apr25a.ino.hex:i 

and this problem is almost certainly caused by not selecting an option from tools → programmer, that is arduino as ISP was selected when he was pointing the IDE at an official arduino board. Now, there will be a blank spot next to the programmer option where it normally shows the selected programmer; when this happens the platform.txt from the OTHER CORE is being used, and the one from the current core is ignored. In the case of these parts, the manifestation is that it just uses the wrong avrdude.conf, so some parts work and others don’t. If the architectures are incompatible, you get null pointer errors, and switching betrween my two modern AVR cores, you get errors about {bootloader.CODESIZE} or {bootloader. BOOTEND} not being a valid memory type. The bottom line is that you should always make sure that the programmer is actually selected. 1.8.13 made it so you can’t select programmers for other hardware packages, but it didn’t do anything to handle the case when you already have one selected and don;'t change it.

Well as i mentioned on github already, i can’t get the IDE to use the proper file. The selection is never empty, and when i select a different programmer and switch back to ‘Arduino as ISP’ it still picks the wrong file. That i am switching between cores makes sense (even just to upload to an ATTiny i must first load ArduinoISP onto my UNO, then upload to the ATTiny, then i upload a version of blink onto the UNO to test the UART etc.
To me the whole structure seems faulty, where do all those definitions in the ‘wrong’ avrdude.conf file come from ? Either there should be just a single file, or there should be just a single entry for each board.

What version of the IDE are you running?

Do you see multiple copies of Arduino as ISP in the tools → programmers menu? If so it sounds like a pre-1.8.13 version; one of those is the one that is defined by ATTinyCore and will work…I used to have (ATTinyCore) after all of my programmers as the workaround for this, but after the new version had been out for a bunch of months with no major problems reported (the bug I’m talking about here is the only one I know of, and it’s easily worked around - it’s definitely the best IDE version yet), they were deleted from the names when I overhauled the names of the programmers recently.

I am running 1.8.12, but i will get around to updating at some point. This has been a rather educative thread for me. I kept having to change the settings for other boards every time i switched between them, but now i know how i can set the default setup.
