Hi,
I have about 3 thousand Attiny11 chips that I am trying to program with the STK500 that I just purchased. I understand that I have to program them in the high voltage serial mode and that the jumpers have to be set correctly and I have done all that.
I still cannot program the chips or the fuses. I have the programmr working and can program all other Atmel Avr's,, its just the tiny11 that I have a problem with. It will not program the chip or read it. Any idea what I am doing wrong or missing?
Thanks

Hi,

At what voltage are you running the STK500?
To successfully program in high voltage serial mode, the voltage on the STK500 board must be set higher than 4.5V (Board options in the STK500 software).

(The same apply for parallel programming)

Thanks for the reply,, the voltages are set at 5.2 volts. When trying to write to the chip it says
Entering program mode ok
Erasing ok
Programming flash using block mode 0% failed
Leaving programming mode failed

Ok.

There is a typo in the user guide: section 3.7.2.2 step 7:
RST pin on PORTE is PIN4 not PIN3.

Could this be the problem?

Thats ok,, I figured that one out! Is there some voltages I can trouble shoot?

Should the reset pin be 12v during programming cycle? Its not here?
