Bricked ATTINY SMD

2012-11-20 by Dave McLaughlin

Hi all,

 

I have inadvertently bricked an ATTINY13 after trying to set the fuses.

 

I was trying to set the 4MHz speed with 64ms start up and also enabling the
Debug Wire interface.

 

Now I can't talk to the device at all.

 

I have searched around and found some stuff on the high voltage programming
but all the ideas seem to be to work with the DIP package and I have the SMD
package on my board.

 

Does anyone know how to get this to work with SMD or a suitable device I can
purchase that might plug over the top of the IC and allow it to be
programmed? I can isolate all the IO pins to do this. Unsoldering it is not
an option unless I am stuck with replacing it.

 

Cheers

Dave.

 

PS.. Can I actually programme the fuses on this device to get debug-wire to
work?

Well you may have:

1) Set the AVRs clock to be too slow for the SPI clock speed in your ICSP.
Try slowing your ICSP programmer speed right down.

2) you've enabled the external xtal/clock so it will now need some sort of
clock signal on that pin, while you revive it by setting the fuses with a
ICSP Programmer back to what you need.

Thanks Alex,

 

I tried slowing the SPI clock. No reply.

 

I didn't enable the external clock. I enabled the internal RC 4Mhz and 64ms
reset option with CLKDIV8 enabled.

 

Dave.

Dave,

I make a board that uses an ATTINY2313 in a SOIC package.  I program it using a Pomona Clip that clips onto the leads that are soldered to the board.  You can see it in action on my web page:

http://gardnerswebsite.com/ninjamods/index.html

There's also a link on that page to a pdf data sheet for the clip.

Hope this helps.

Bob

Thanks for the idea Bob.

 

I have ordered a clip for this today and will build up the rest of the
circuit to do the high voltage programming.

 

Cheers

Dave.
