attiny bootloader not compiling

Projects Programming
1

I am trying to get a simple blink sketch to work on the attiny85 to make sure that the ISP and everything is working properly
Here's the reference i'm using for the wiring:
http://hlt.media.mit.edu/?p=1229

I am using an UNO.
I uploaded the arduinoISP code attached in this message that was provided by Coding Badly
I selected the Attiny85 @ 8Mhz

When i tried to burn the bootloader, this is the error message that popped up.

avrdude done.  Thank you.

any idea what's going wrong? thank you

  1. Open Arduino IDE. Open File | Examples | ArduinoISP.
  2. Upload this sketch to you Uno.
  3. Click Tools | Programmer | Arduino as ISP
  4. Change board type in Tools | Board | ATTiny85 (internal 8 Mhz clock)
  5. Click Tools | Burn Bootloader
  6. You can now upload your code through the Uno via File | Upload using Programmer

If you're already doing all of this, confirm your connections from the Uno to the ATTiny85:

  1. +5V on Uno to VCC on chip
  2. Ground on Uno to ground on chip
  3. Pin 10 on Uno to pin 1 on ATTiny85 (reset)
  4. Pin 11 on Uno to pin 5 on ATTiny85 (MOSI)
  5. Pin 12 on Uno to pin 6 on ATTiny85 (MISO)
  6. Pin 13 on Uno to pin 7 on ATTIny85 (SCK)

Good luck!

  1. Open Arduino IDE. Open File | Examples | ArduinoISP.

The version that comes with the IDE does not always work on Linux / Mac computers (the /Applications/Arduino.app directory is a good indication that @Drc3p0 has a Mac).

avrdude: Recv: . [15] 
avrdude: stk500_getsync(): not in sync: resp=0x15

Huh. That's a symptom I've never seen. @Drc3p0, you sure have a knack for getting entangled with strange problems.

I suspect the Uno bootloader is responding instead of the ArduinoISP sketch. Make certain...

• The disable-auto-reset capacitor is put in place after uploading the modified ArduinoISP sketch

• The disable-auto-reset capacitor is making good electrical contact if, like me, you connect it directly to your Uno

I just tried the ISP sketch you provided, and got the same error.
I am using Windows Vista, and Arduino 1.01

I tried the blink sketch

Next option was to try this modified ISP

Arduino translated to AVR? - #40 by Coding_Badly - Programming Questions - Arduino Forum reply #39.

It worked without errors, so I believe there is an error in your ISP sketch, or shouldn't it work on a MAC ?

Erni:
...or shouldn't it work on a MAC ?

It's an earlier attempt to get past a Linux / Mac related bug in ArduinoISP. The sketch in reply #39 is the latest (and apparently more successful) attempt.

Some details about the first attempt...

I had instituted this file change based off of previous instructions. Not sure if it could contribute to the issue at hand... I am using arduino Uno version 1.0

That takes care of the linker problem.

Instead of the ArduinoISP sketch you are currently using, try the one @Erni suggested in his post...
