Digispark-tiny upload error

[fitzterra]

Trying to upload to a digispark-tiny (arduino, attiny85) via micronuclues fails with:

$ platformio run -e digispark-tiny -t upload
[Wed Dec 23 08:27:59 2015] Processing digispark-tiny (platform: atmelavr, board: digispark-tiny, framework: arduino)
-----------------------------------------------------------------------------------------------------------------
BeforeUpload(["upload"], [".pioenvs/digispark-tiny/firmware.hex"])

"/home/tomc/.platformio/packages/tool-micronucleus/micronucleus" -c digispark --timeout 60 .pioenvs/digispark-tiny/firmware.hex
sh: 1: /home/tomc/.platformio/packages/tool-micronucleus/micronucleus: not found
scons: *** [upload] Error 127

There is no pause at the point where the message Please unplug/plug device ... comes up and the error appears immediately.

This is on a Xubuntu 15.10 64-bit machine with PlatformIO installed inside a virtualenv.

Looking at the micronucleus binary, it seems it is a 32-bit version. Not sure if this is the issue:

$ file /home/tomc/.platformio/packages/tool-micronucleus/micronucleus
/home/tomc/.platformio/packages/tool-micronucleus/micronucleus: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=37731088830509f6a90d9765e9784239bb32ffc8, not stripped

Anyone seen this before or have any advice?

Thanks,
Tom

@valeros please check that this 32-bit binary works on 64-bit host OS

Hi @fitzterra
Could you test upload with this micronucleus:

I got it to work by doing the following:

• installing lib32stdc++6 from the package manager - I doubt if this has anything to do with the result, but saw somewhere that it may be needed for the USB support
• copying the 64-bit micronucleus from the Digistump v2.04a library installed by the Arduino library installer.

Here are my current ~/.platformio/packages/tool-micronucleus dir:

$ ls
micronucleus  micronucleus.orig

The .orig version is the original installed by platformio and the other is the one from Digistump:

$ file *

Does this help?

@fitzterra Please, update your tool-micronucleus package via platformio update

[fitzterra]

@valeros A great big thank you! After the update I now have a 64-bit micronucleus and the unplug/replug pause and timeout seems to work perfectly. I can only test and actual flash tomorrow and will report here if it does not work, but am confident the issue is now resolved.

A great big thank you for your effort on Christmas Eve (or Christmas Day, depending where you are :-) ) - much appreciated.

@fitzterra please reopen this issue if it doesn't work.

@fitzterra I would recommend you to gift @valeros ⭐ here https://github.com/platformio/platformio/stargazers. He likes them 😊 🎄
