Arduino flash issues

[pierreis]

On a Mac, I continuously get issues when flashing an Arduino Uno board via tinygo, with the usual error:

playground » tinygo flash -target arduino -port=$UNO_DEV_PATH -scheduler=coroutines ./main.go                                                                            ~/L/P/a/playground

Note that the flashing sometimes works fine (but mostly doesn't).

I do not have any issues whatsoever flashing the board using the Arduino IDE ; only with tinygo from the command line.

Thanks to some help on discord, I have tested using arduino-cli for flashing, which consistently works just fine:

tinygo build -scheduler=tasks -target=arduino -o /tmp/test.hex ./main.go && arduino-cli upload -b arduino:avr:uno -p $UNO_DEV_PATH -i /tmp/test.hex .

tinygo flash remains flaky at best though.

Perhaps you have an older version of avr-dude installed? That is what the tinygo flash command currently uses "under the hood". Did you install avr-dude via homebrew?

[pierreis]

I did install via homebrew indeed. Installed version is 6.3, which seems to be the latest.

[deadprogram]

Which macOS version?

[pierreis]

11.1

[deadprogram]

I am still running Catalina on my dev machine. I wonder if that is related?

[pierreis]

I suppose that is a possibility. Anything I could provide to help debug this?

Oops, sorry I never got to this issue! I suspect this can be solved using -target=arduino-nano-new.

[peritonow]

indeed it does running on Windows 10 - going by tutorial on https://tinygo.org/docs/tutorials/blinky/ and https://tinygo.org/getting-started/install/windows/ steps for scoop. Thank you.

I am using linux (raspi) day to day as a main platform. This is my first intro to tinygo. :-)
