Attiny85 usbasp programming - works on Arduino IDE, fails on PlatformIO

Hi
I’m trying to upload basic blink code to attiny85 using a cheap USBasp programmer (from China).
Here is my platfomio.ini config :

[env:attiny85]
platform = atmelavr
board = attiny85
framework = arduino
board_build.f_cpu = 1000000L
upload_protocol = usbasp
upload_flags = 
    -Pusb
    -v

It does not work. Error messages is :

avrdude: error: program enable: target doesn't answer. 1 
avrdude: initialization failed, rc=-1

If I use ‘-F’ option, avrdude complains about bad signature of the chip ?!

I’ve tried Arduino IDE to program attiny85 (using ATtinyCore) and I was able to succesfully program it several time (to change delays for example).

Any help appreciated.

With the exact same programmer and wireup?

Also, can you show a screenshot of your Arduino IDE configuration (board, programmer, …).

Yes : no change to wiring of usbasp and attiny85 on breadboard

ArduinoIDE

Hm I don’t really see much difference between the Arduino IDE invocation and the PlatformIO invocation for that platformio.ini.

For Arduino IDE:

avrdude -CC:\Users\Maxi\AppData\Local\Arduino15\packages\ATTinyCore\hardware\avr\1.4.1/avrdude.conf -v -pattiny85 -cusbasp -Uflash:w:C:\Users\Maxi\AppData\Local\Temp\arduino_build_698574/Blink.ino.hex:i

For PlatformIO:

avrdude -Pusb -v -v -p attiny85 -C C:\Users\Maxi\.platformio\packages\tool-avrdude\avrdude.conf -c usbasp -e -D -U flash:w:.pio\build\attiny85\firmware.hex:i

Can you change the upload_flags value to not include -P and retry?

Also upload full “Verbose Upload” log from PlatformIO and Arduino IDE (activatable in File -> Settings -> Tick box for “Upload” )

Hi (and thanks for the support !)

Let me mentioned that I’m using Arduino IDE 1.8.13.

This is Arduino verbose output :

Interesting, some delay settings and SCLK configs are missing.

I’ll have a look. Maybe it comes down to the different avrdude.conf being used.

The AVRdude output is verbose, but PIO’s output is not – have you ran the Verbose Upload for sure in PlatformIO? Also the AVRDude invocation line is missing in the Arduino IDE output.

WIll do.
For sure, avrdude versions in Arduino and PIO aren’t the same :slight_smile:

  • Arduino : avrdude: Version 6.3-20190619
  • PIO : avrdude: Version 6.3, compiled on Sep 12 2016 at 15:21:49 (!older!)

By the way : how do you run a “Verbose Upload” in PIO ? :thinking:

I’v managed to upload the blink application to attiny85, by copying avrdude.conf from arduino to PIO.

Files are really differents :

  • Arduino avrdude.conf is 177692 bytes long,
  • PIO avrdude.conf is 518870 bytes

pio run -v -t upload or “Verbose Upload” task (docs, under “Advanced”)

So it seems that the avrdude.conf of this core has a slightly different config for the ATTiny85 than the standard one. Please open a bug at https://github.com/platformio/platform-atmelavr/issues to get this fixed in the tool-avrdude package or the platform code.

Ok…
That’s a follow up message on this topic.

One of the differences in Compilation/Upload between the Arduino and PlatformIO IDE is this line (in verbose mode !) :
Setting bit clk period : 5.0
This seems to be atuomagically added in Arduino IDE…

When you set upload_flags to “-Pusb -B5” in platformIO: it solves the problem as well (no need to modify the avrdude.conf file)

I’ll update the issue as well.
