is there a running processor clock (internal or external)?

Hello all,

I am having some problems with building a replacement for an AVRISP. 
The schematic is in the files section (AVRISP.DXF). I get errors when 
I try to program the AtTiny2313 with AVR Studio 4. 

Setting mode and device parameters.. OK!
Entering programming mode.. FAILED!
Leaving programming mode.. OK!

The 2313 does have external power and the jumper on the reset line is 
on. I did check to make sure the reset line is being pulled low. Is 
there anything obvious that I am missing? Here is the reference 
design I was trying to copy.

20Programmer.htm

The only reason I am trying to copy this is because we are still 
using the AtMega103 and need a programmer. The MKII does not support 
the 103.

thanks,
Draper

But looks like you are trying to use it as a STK500 which it is NOT.
Try and use AVRProg instead.

Unless you tell it too. I can't remember where but it is just a matter
of adding some text to say that the m103 is supported and it should work.

May want to do a search on AVRfreaks where it has been mentioned before.

Draper,

As another poster (Jim) remarked this looks most like a problem with
the clock or your connections to the programmer. If you are not using
the internal clock and are using the external 7.3728 Mhz crystal, then
you may have botched the fuses. Luckily you have a STK500 and might be
able to use the XT1 to rescue the tiny2313.

The fuses for the tiny2313 AVR910-based programmer are:
EFUSE 0xff
HFUSE 0xdf
LFUSE 0xed

That sounds all ok. Double-check all SPI, power and crystal
connections to the tiny2313.

This is from my hobby project website. It is an AVR910-based
programmer. When you read the article you will notice that I also give
credit to Klaus Leidinger (and team) who originated the design and
software. I just made a few simple updates and showed how it could be
made on inexpensive stripboard. In my latest version I replaced the 6
pin SIL socket with a regular 10-pin AVR. Total cost is still less
than $9 if you build it yourself.

If you are still having trouble, contact me offline (mikep at
oakmicros dot com) and I can sell you an already programmed tiny2313
from my Oak Micros website. The cost would be less than $3 not
including first class postage. If there is sufficient interest I can
make more available or even a kit of parts.

You may also be interested in browsing some of the other AVR-based
devices I have for sale.

This would be the easiest solution. I checked out avrfreaks.net and 
couldnt find anything. Is it just a matter of finding the *.c or 
*.asm and adding the device code?

Thanks a bunch. I dont have my MkII with me but I am going to modify 
the XML first thing Monday and test it out on some of our ATmega103 
devices.
