Digispark upload

[BetterCall]

Bug Report

Environment

• CLI version (output of arduino-cli version):0.20.2 commit 1378381 date 2021-12-09t13:32
• OS and platform: windows 10

Current behavior

arduino-cli.yaml is ok

Additional_urls : 
  - http://digistump.com/package_digistump_index.json

Packages et boards downloaded with arduino-cli.exe core install digistump:avr

arduino-cli.exe compile -b digistump:avr:digispark-tiny
arduino-cli.exe upload -b digistump:avr:digispark-tiny

If you never compiled and uploaded sketch to digispark with the arduino gui the upload command runs without uploading or returning error
Cmd :
Running Digispark Uploader …
Plug in device now … ( will timeout in 60 seconds )

At this point, cmd just end without timeout, but once you set preference in the GUI added additional boards urls, board, compiled and uploaded with GUI
The command arduino-cli.exe upload -b digistump:avr:digispark-tiny works like a charm

Reproduce

Never uploaded sketch to digispark with GUI

download arduino-cli.exe
Add http://digistump.com/package_digistump_index.json to the additional_url

arduino-cli.exe core install digistump:avr

Create .ino
arduino-cli.exe compile -b digistump:avr:digispark-tiny
arduino-cli.exe upload -b digistump:avr:digispark-tiny

Additional context

The application embed arduino-cli in electron app so upload works only if user already upload to digispark before

Hi @BetterCall. If you run the arduino-cli upload command with the --verbose flag, you can see the upload command generated by the digistump:avr boards platform.

It will look something like this:

"C:\Users\per\AppData\Local\Arduino15\packages\digistump\tools\micronucleus\2.0a4/launcher" -cdigispark --timeout 60 -Uflash:w:C:\Users\per\AppData\Local\Temp\arduino-sketch-5162AF43A5C9EEB136B73635BA92A5B1/Foo.ino.hex:i

If you run that command directly from the command line, you will get the same result of it exiting immediately rather than waiting for the board to be connected.

This means that the problem is with the upload tool provided by the digistump:avr boards platform, not a problem with Arduino CLI. Unfortunately, DigiStump ceased supporting their software years ago, so you won't be able to get a fix from them.

Fortunately, the Arduino community has stepped in to carry on this project. You can find an excellent fork here:
https://github.com/ArminJo/DigistumpArduino
and ATTinyCore also has recently added the Micronucleus support:
https://github.com/SpenceKonde/ATTinyCore/blob/master/avr/extras/UsingMicronucleus.md
I think you will find success with either of those platforms.
