Upload using programmer: bundled avrdude fails to verify, post upload

Development Tools Uploading
1

Ext. Programmer: Atmel ICE
Board: Arduino Uno
Arduino IDE version: 1.8.19
System: MacOS ventura

What am I trying to do?
Upload using Programmer

What's the issue?
Compiled Hex uploads, but fails to Verify and throws error in the verbose output of IDE.
Same issue for IDE 2x
It get's written, I know, as my program (blink.ino) makes the built in led blink and even if I change the duration, it get's changed.

How am I uploading the program?
Well you know, Select the programmer as Atmel Ice (AVR) , then select the board as Arduino Uno, then Hit Upload Using Programmer

What's the error?
Here's the dump:

avrdude done.  Thank you.

What did I try next?

  • Installed avrdude (using homebrew). It's version 7.2
  • I compiled and exported the hex using arduino-cli:
arduino-cli compile -b arduino:avr:uno --build-path $(pwd)/build
  • Then Uploaded using the system's avrdude:
avrdude -catmelice_isp -pm328p -v -Uflash:w:build/blink.ino.hex:i

Result: No error, clean build and upload.

What I noticed is: avrdude bundled in Arduino IDE's is 6.something.
Also I get error to burn bootloader using ATMEL-ICE, from IDE.

Any pointers, how to update the avrdude, if that's causing the issue.
Before I go down the rabbit-hole, I thought of asking here first.
Thank you for all your help in advance.

UPDATE
I edited the programmers.txt to use the latest avrdude and not the bundled one as the one I installed via homebrew is of version 7.2 and as we already know that running avrdude (v7.2) from commandline throws no edbg error.

Steps I took:

  • Locate programmers.txt

For IDE 2.21, on macOS, it is located at:

/Users/<user_name>/Library/Arduino15/packages/arduino/hardware/avr/1.8.6/programmers.txt

For IDE 1.8.19, on macOS, you have to right click on the Arduino app; Click Show Package Contents and navigate to:

Contents/Applications/Arduino.app/Contents/Java/hardware/arduino/avr/programmers.txt
  • Locate programmers.txt and find the section related to Atmel-ICE (it's the last items)
    The default section has the below entries where it uses the bundled avrdude (6.xx)
atmel_ice.name=Atmel-ICE (AVR)
atmel_ice.communication=usb
atmel_ice.protocol=atmelice_isp
atmel_ice.program.protocol=atmelice_isp
atmel_ice.program.tool=avrdude
atmel_ice.program.extra_params=-Pusb

Modify it to include the externally installed avrdude (homebrew version)

atmel_ice.name=Atmel-ICE (AVR)
atmel_ice.communication=usb
atmel_ice.protocol=atmelice_isp
atmel_ice.program.protocol=atmelice_isp
atmel_ice.program.tool=/opt/homebrew/bin/avrdude
atmel_ice.program.tool.default=/opt/homebrew/bin/avrdude
atmel_ice.program.extra_params=-Pusb -C/opt/homebrew/etc/avrdude.conf
atmel_ice.program.pattern=/opt/homebrew/bin/avrdude -C/opt/homebrew/etc/avrdude.conf -v -patmega328p -catmelice_isp -Pusb -Uflash:w:{build.path}/{build.project_name}.hex:i

Restart the IDE and after selecting your correct board and programmer as Atmel-ICE (avr), either press shift+command+u or click Upload Using Programmer from the Sketch menu.

And? No error :kissing_heart:

Very hacky and hard coded for uno only process for now though. But it proves that the errors were coming because of the older avrdude version.

Any pointers on how to resolve this using the bundled avrdude version?
