Flash a .hex to an ATtiny45 with Arduino

Question

I'm trying to upload a hex file to an ATtiny45 with an Arduino. I uploaded the Arduino ISP sketch to my board. I connected the ATtiny as shown below:

Then I go to CMD and type:

avrdude -c avrisp -p t45 -b 19200 -P COM6 -U flash:w:main.hex:i

And it gives me this error:

Please define PAGEL and BS2 signals for ATtiny45!

I double checked the connections and i tried to uplad a bootloader with Arduino IDE as written in this article: Programming Hex-code on an Attiny85 with the Arduino. I can uplad sketches with ArduinoIDE with no error.

Answer 1

Googling the error gives this tutorial. Towards the bottom of the page they say

You’ll probably get the following message, but don’t worry, the upload should have worked anyway:

avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny85

So it seems this can be ignored and the part has been programmed!
