Platformio-core: digispark-tiny upload failing

[jonlorusso]

digispark-tiny upload is failing:

platformio run --target upload

Fails with:

[Tue Mar 3 20:01:16 2015] Processing digispark-tiny (platform: atmelavr, board: digispark-tiny, framework: arduino)
BeforeUpload(["upload"], [".pioenvs/digispark-tiny/firmware.hex"])
scons: *** [upload] Explicit exit, status Error: Please specify upload_port for environment or use global --upload-port option.

Error: Please specify upload_port for environment or use global --upload-port option.

When uploading to the digispark via micronucleus I am normally prompted to insert the device. No port name is required.

Thanks a lot for report! This is a bug, I will fix it as soon as possible! Current solution is to put "something" to --upload-port, like:

> platformio run -t upload --upload-port /dev/null

Does it work for you?

[jonlorusso]

$ platformio run --target upload --upload-port /dev/null

At this point, output pauses, and I plug in the device (despite not being prompted to). Once I plug in the device, I see:

Please plug in the device ...

@jonlorusso We will fix it tomorrow. I've just opened for it separated issue https://github.com/ivankravets/platformio/issues/107

It seems that this error is caused by usb permissions issue.
Did you try to insert platformio udev.rules file? https://github.com/ivankravets/platformio/blob/develop/scripts/99-platformio-udev.rules

Getting closer:

Fixed in https://github.com/ivankravets/platformio/issues/107 and will be released in PlatformIO 1.0.2 today.

Please re-open if you still have this issue.

[ivankravets]

Could you try new version 1.1.0? Please use platformio upgrade command.

Thanks in advance!

For future Googlers: a similar problem occurs in OS X with USB3 ports. Try connecting the target device via a USB2 hub.

Case of mine, a workaround is to just press Upload, then power up device AFTER process is trying to upload (it will be paused for a while, no need to be a ninja).
No device in list, just install micronucleus drivers then voilá.

https://github.com/micronucleus/micronucleus
https://github.com/micronucleus/micronucleus/tree/master/windows_driver

In my particular case, i have atinny85 usb device, i found and used those drivers:

Hope this helps.
