Hi:
I am following these instructions to program Attiny85:
http://hlt.media.mit.edu/?p=1229
First of all, I have realized that we cannot use arduino IDE 1.0. So I downloaded version 0022. There are no compiling errors in this version.
However, as I try to upload the simple blink example, moving the output to pin 2, I obtain these results:
Problem uploading to board:
Binary sketch size: 658 bytes (of a 8192 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
I am doing exactly the same steps and connections as that webpage states... what is wrong?
Thanks in advance
Did you disable auto-reset using a 10 uF capacitor?
Did you disable auto-reset using a 10 uF capacitor?
Yes, following exactly those instructions.
The error indicates that either the Arduino ISP sketch is not installed or that auto-reset is still firing. I suggest working through the steps a second time.
http://hlt.media.mit.edu/?p=1695 (http://hlt.media.mit.edu/?p=1695) Updated for UNO and 1.0 IDE. Works well, I have tested it. Of course, Coding_Badly's response still applies, but also make sure everything is wired and powered correctly. I spent an hour messing with the IDE files only to realize my reset resistor was connected to GND. :smiley-red:

Thanks a lot.
I am taking breakfast now, no time to check it.
This afternoon I will try it.
Please, help me. =( =( =(
I cannot find anything wrong. Follows some pictures with all the info.

I have changed the capacitor as well, just to check whether it was defective.
any feedback? Thanks.
And I have tried to burn the bootloader to run at 8MHz, and I obtain the same error:
avrdude: stk500_getsync(): not in sync: resp=0x00
More trials...
I am not sure whether I have to use a capacitor or a resistor to disable the autoreset. So now I have used a 150 Ohm resistor (not have 120) between Reset and Ground. Is this another option? is this right?
Anyway, I obtain the same error as before. This is really frustrating....
Now I tried reset-resistor-+5V... same error...
The wiring looks fine.
I am not sure whether I have to use a capacitor or a resistor to disable the autoreset.
You may not have to use either. The latest Optiboot does not require disabling auto-reset. If you purchased the Uno recently, it may already have a "good" bootloader installed. Try...
- Removing the capacitor and / resistor
- Re-uploading the ArduinoISP sketch (don't forget to change the board selection to Uno)
- Uploading a test to the ATtiny
So now I have used a 150 Ohm resistor (not have 120) between Reset and Ground. Is this another option? is this right?
http://www.arduino.cc/playground/Main/DisablingAutoResetOnSerialConnection
Don't go below 110 ohms or above 124 ohms
Do you have another Arduino board?
I have a nano as well, can I use it?
removing capacitor or resistor does not help....
so this is what I have done:
I load file/examples/ArduinoISP
I set board = Arduino Uno
I upload it
No errors
Then I load Blink example.
board = Attiny internal 1MHz
Programmer = Arduino as ISP (and this was selected before, for the previous case as well)
I upload it
I get this error:
Binary sketch size: 768 bytes (of a 8192 byte maximum)
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: stk500_cmd(): programmer is out of sync
in the last case, if the capacitor is used. the error is:
Binary sketch size: 768 bytes (of a 8192 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
I have a nano as well, can I use it?
It should work well. I suggest using the 120 ohm resistor method to disable auto-reset. You will have to find a combination of resistors to get the value in the correct range. I don't know if using a capacitor is appropriate with the FTDI chip.
If you get the Nano working as an ISP, I also suggest updating the Uno bootloader. Not having to fiddle with auto-reset is very nice!
removing capacitor or resistor does not help....
Unfortunately, you are not the first person to have trouble disable auto-reset on an Uno. You may want to search through the forum for other suggestions.
And just to make certain you are not wasting your time with the Nano... Whenever you get the "expect=0x14, resp=0x51" error or the "not in sync: resp=0x00", you have to re-upload the Arduino ISP sketch. There is a very good chance the sketch was erased when the bootloader ran. If you have not been re-uploading the Arduino ISP sketch when that error occurred, this would be a good time to start from scratch using the capacitor to disable auto-reset.
so this is what I have done:
I load file/examples/ArduinoISP
I set board = Arduino Uno
I upload it
No errors
Did you disable auto-reset at this point?
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
These can be ignored.
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: stk500_cmd(): programmer is out of sync
Huh. That's different.
I was able to burn the bootloader (for 8MHZ option) using the method of holding the reset button, as described here:
http://www.arduino.cc/playground/Main/DisablingAutoResetOnSerialConnection
However, I cannot upload the Blink example after that. I have first upload again the ArduinoISP sketch...
error=
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: stk500_cmd(): programmer is out of sync
If I am quick enough for setting 8Mhz... it is very strange it does not work for the Blink example...
I feel extremely tired....
More tomorrow..
why don't you add an 120R resistor between reset and +5V or a capacitor between reset and GND ?

As I posted before, I have add a capacitor, remove it, with no success. I will try resistor.
As a curiosity, when i plug the capacitor, and the board is powered, the board resets itself... :smiley-eek:
What I found to work, 10k resistor between attiny RST and +v AND 22nF cap between attiny RST and Arduino reset pin. No modification/parts added to arduino. Don't remember where I found these instructions. Let us know.

I have used your method. It does not work :~
I have used a 120K resistor.... it does not work.... =(
What i can do is burning the bootloader to have 8MHz option. I can do this with the 120 resistor, or holding the reset button.
Why can I set the fuses up, with no errors, but I cannot upload the Blink example?
This is extremely frustrating...
I think that with the resistor I have disconnected the auto reset. Led associated to pin 13 does not blink during upload, and now the error is different:
Binary sketch size: 768 bytes (of a 8192 byte maximum)
avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85

avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64
avrdude: stk500_cmd(): protocol error
any idea about the meaning of this error?
I think that with the resistor I have disconnected the auto reset. Led associated to pin 13 does not blink during upload, and now the error is different:
Or, the Arudino ISP sketch has been erased.
Connect an LED to pin 9. When the ArduinoISP sketch is idle, does the LED on pin 9 slowly get brighter then dimmer?
When you try to upload to the ATtiny, does the LED on pin 9 blink?

Thanks for your interest.
I connected the led.
When ArduinoISP is idles, yes, LED on pin 9 slowly gets brighter then dimmer.
If I upload
again ArduinoISP skecth I can see the led
blinking. That's good.
However, when I try to upload the Blink example, Led does not blink, stays on. Then an error is written, and the led gets brighter and dimmer again, so the ArduinoISP sketch is not erased, but the Blink example is not uploaded.
So I think that the situation now is: I have stopped the auto reset, but I cannot upload the blink example to the ATtiny85.
I have used another Attin85, with the same result. Yesterday i tried arduino nano with no success. At this pointy I think I will never do it....
:smiley-eek:
Don't get discouraged. This took me a week (or two) to get working. What I posted wasn't my actual setup anyway, (http://insapio.files.wordpress.com/2011/12/breaduinoprogrammingattiny85.png is, however.)
I was getting the same error as you for at least a week. You might need to erase your Uno, disassemble your setup, and try out some other projects for a few days. Come back to it fresh. I dunno why, but that always helps me.
I also got to the point where I completely deleted the IDE, reinstalled, added back the tiny cores (the new 1.0 cores of course) and gave it another go. I'd done an inordinate amount of fiddlin' with my boards.txt and the avrdude.conf files, so ymmv.
Perhaps the only solution is buying one of these programmers:

I am spending too much time on this problemm, even I am taking too much time from you... sorry for that....
Ha, no problem man, I've got infinite free time! But yeah, one of those should work out of the box. Although, so should the ArduinoISP :~
I have good news, annoying news, and good news.
First the good news. I've reproduced the problem and I know what is wrong.
Now for the annoying news. Arduino 1.0 and the ArduinoISP sketch are not compatible. There are some problems with the ArduinoISP sketch and Arduino 1.0 surfaces at least one of those problems.
And, finally, the good news. I have an update for the ArduinoISP sketch that works correctly with Arduino 1.0. If you'd like a copy, send me a Personal Message (http://arduino.cc/forum/index.php?action=pm;sa=send;u=10859) with your email address.

Thanks a lot!!!
Email sent.
So perfect work. Thanks a lot!!!
Now I can finally program the ATtiny85...
Here just a simple sound sensor that activates a relay... working!

That's great!
Over here no succes yet.
Instead of that I get this:
After Burning Bootloader to ATtiny45
(http://img508.imageshack.us/img508/7140/errormessageburningboot.jpg)
This should be ok.
And then it happened:
After trying to upload the sketch to the ATtiny
(http://img803.imageshack.us/img803/8416/errormessageuploadingsk.jpg)
What went wrong?
How did you disable auto-reset?
Is the LED on pin 9 fading when the TinyISP sketch is idle?
I know that the question is not for me, but in my case, I used the 120 Oh resistor, adding two resistors to get that value.
I have to check pin 9 with a led.
I used a 10 uF from an old VCR so it might be faulty or the legs are too short to use in the bread board. New ones are on their way.
I will put a led on pin 9 and try a resistor.
(I bought a clone Uno so I don't know what bootloader is on the Uno itself)
I'm going to try again, I'm new at this so my stock of resistors is limited but I will try.

I've made this configuration with a couple of resistors to get exactly 120 ohms.

Now I get this error message after the Rx led on the Uno flashes three times:
(http://img195.imageshack.us/img195/8416/errormessageuploadingsk.jpg)
This is the orientation of the ATTiny in the bread board wrt it's connections.
(http://img825.imageshack.us/img825/8250/orientationofattinyinbr.jpg)
(I previously bent the legs of the cap for a better fit in the bread board but no results there)
(I'm going to clear everything today to put an extra lamp on the ceiling tomorrow)
EDIT:
It's working now!!!
I made the rookie mistake of not connecting the ground of the chip after I used the ground lead for the resistors and I left the cap and resistors out and now it works.
So the auto reset is not disabled. I also connected a led to pin 9 to see the heartbeat.
Thanks guys for the support.
Here a short vid of the result.
Brake lights for my Team Associated SC10 short course race truck.
(you cannot see it clear on the vid but the leds burn when the brake is engaged, with the potmeter I can tune the moment of engagement to follow trim of the ESC if necessary)
