Outdated micronucleus tool (mac)

[ex-punctis]

When I pick digispark-usb as the board, PlatformIO installs micronucleus tool version 1.2 (mac binaries) whereas the current version is >2. I wonder if there is a way to modify some setting so it fetches the latest version instead?

We use the latest compatible 2.0 version. X.Y.Z is internal version naming. See Y as a real version name.

Thank you for your response. Unfortunately, the current version of the command line tool doesn't work with version 2.03 bootloader from https://github.com/micronucleus/micronucleus

The following error is reported:

Warning: device with unknown new version of Micronucleus detected. This tool doesn't know how to upload to this new device. Updates may be available. Device reports version as: 2.3

Since digispark clones are likely to come with the latest version of micronucleus, it might be worthwhile updating the command line tool to bring support for this version. I believe the command line tool is backwards compatible, so devices with older versions of the bootloader should not be affected.

Does it work with Arduino IDE https://digistump.com/wiki/digispark/tutorials/connecting ?

[ex-punctis]

Yes, it does work with digispark in Arduino IDE using the package you linked. The tool reports version 2.0a4 (whereas the latest one available directly from https://github.com/micronucleus/micronucleus is 2.0a5).

Packages are updated. Please run pio update.

Does it work now?

[ex-punctis]

@ivankravets It works now, thank you.

Happy coding with PlatformIO! 😊

I still have this issue. I am using platformio on arch linux within visual studio code. It installs this version:

{
    "description": "Micronucleus",
    "name": "tool-micronucleus",
    "system": [
        "linux_x86_64"
    ],
    "url": "https://github.com/micronucleus/micronucleus",
    "version": "1.200.4"
}%   ```
which is not compatible with the 2.3 bootloader. However if I replace the micronucleus binary with a current version from an arch-linux package, it works.
I did an pio update but it did not update anything.

Yep, this is an issue again. I flashed the micronucleus bootloader compiled from current master (e74ce6f) to an ATtiny85, which reports as being device version 2.4:

Warning: device with unknown new version of Micronucleus detected.
This tool doesn't know how to upload to this new device. Updates may be available.
Device reports version as: 2.4

I can't seem to find the repository from which tool-micronucleus is installed? Is there a place one could correctly create a pull request against? Either way, @ivankravets please reopen.

This is my platformio.ini:

[env]
framework = arduino
platform = atmelavr

[env:tiny85]
board = attiny85
board_build.f_cpu = 16500000
upload_protocol = micronucleus

---

Overwriting the micronucleus binary in ~/.platformio/packages/tool-micronucleus/ with one that I compiled myself from master works, of course. But this is just a temporary hack.

I'm seeing a similar issue on Linux, it's unable to flash a board which uses the latest released bootloader from https://github.com/micronucleus/micronucleus/releases/tag/2.04

It looks like the platformio micronucleus binary on Linux is a few years out of date, it would be better to update to the latest release, so that it would work with old or new bootloaders.

I've also noticed that the platformio micronucleus crashes if the board is connected when I hit upload; I've never seen that issue on arduino IDE. Replacing with the latest release resolves that issue, and allow me to upload using a reset button.
