Sorry to have to ask another PlatformIO question here.

Where is the source code for https://registry.platformio.org/tools/platformio/framework-arduino-megaavr-megatinycore which references this git repo.

When that package is installed it uses files from https://github.com/SpenceKonde/megaTinyCore/tree/master/megaavr mixed in with files from the root and some files that dont exists, which makes me think the pointer to this repo is incorrect. I want to ask the maintainer to create a 2.6.4 version of the package.

It is possible to install manually by checking out 2.6.4 locally, copying ~/.platformio/packages/ramework-arduino-megaavr-megatinycore (2.5.11) into ~/.platformio/packages/[email protected], replace the 2.5.11 files with the 2.6.4 files (I used symlinks) and adjusting the .poipm and package.json files.

Then to use.

    platform = atmelmegaavr
    platform_packages = 
         platformio/[email protected]

Unfortunately referencing a git repo fails as the version number isn't in the expected format. (too many '.'s)

Please be more specific, can you list which files are treated in what ways? And is this a megaTinyCore bug or a platformio bug?

Here were the "errors" I encountered. It might be expected behaviour rather than any bug.

TLDR, should there be a package.json in megaTinyCore git repo to allow platform_packages to reference the git repo directly ?

Long version:

Starting from a default megaTinyCore install with Platform IO that is currently at megaTinyCore 2.5.11 I wanted to upgrade to 2.6.4 to get the improvements to Serial classes.

So I tried

[env:attiny3224]
platform = atmelmegaavr
platform_packages = 
     platformio/framework-arduino-megaavr-megatinycore @ https://github.com/SpenceKonde/megaTinyCore.git
board = attiny3224

which results a report that the package.json is missing, hence this asking where the git repo that was used to build the 2.5.11 package is.

Then I tried patching the 2.4.6 tag in a branch of my own

[env:attiny3224]
platform = atmelmegaavr
platform_packages = 
     platformio/framework-arduino-megaavr-megatinycore @ https://github.com/ieb/megaTinyCore.git#2.6.4-pio
board = attiny3224
framework = arduino

resulting in exposing a bug in platforms/atmelmegaavr/builder/frameworks/arduino.py which I can report there. (can't parse 2.6.4+sha.9025674 as a package version, too many '.'s)

At which point I thought it would be quicker to manually patch as per https://github.com/ieb/ModbusShunt#megatinycore

Upgrading to 2.6.4 fixed the problem I was seeing (first 7 bytes of a modbus RTU frame being dropped) which are more likely to have been caused by a bug in my code than anything in 2.5.11.

bug in my code fixed. 2.5.11 works just fine, but I would still like to find out how to use 2.6.4 or later releases via a recommended pattern.

If you open the platformio registry page (https://registry.platformio.org/tools/platformio/framework-arduino-megaavr-megatinycore) You can see "Used By" section in the right bar.
It shows "atmelmegaavr" which has source code here https://github.com/platformio/platform-atmelmegaavr. This is probably the palce where the other files come from.

Unfortunatelly I don't know how to force platformio to use last version of megaTinyCode (It shows 2.5.11 for me as well)

And you think I know?! I wouldn't know platform-io from a hole in the ground! I only know how to use the arduino ide and how to make a modern avr walk on its side in assembly :-pme to do? My brain only has 16 bits of address space anyway (ever wonder why i never talk about the m2560? Above 64k words of flash, I'm out of my league!). And here you are asking about some piece of software for desktop pc's with GBs of ram and TBs of nonvolatile memory - what am I supposed to do?!

LOL, poor Spence and his severely constrained wetware...

I am at the moment struggling with the same issue. PIO comes with an ancient (relatively speaking) megaTinyCore and I really wanted the latest one with its I2C fanciness. I did manage to do a local upgrade. Here goes:

First, clone megaTinyCore locally. Then, copy the following snippet into megaavr/package.json:

 {
  "name": "framework-arduino-megaavr-megatinycore",
  "version": "2.6.5",
  "description": "Arduino Wiring-based Framework for Microchip tinyAVR 0-series and 1-series chips (megaTinyCore)",
  "keywords": [
    "framework",
    "arduino",
    "microchip",
    "tinyAVR"
  ],
  "repository": {
    "type": "git",
    "url": "https://github.com/SpenceKonde/megaTinyCore"
  }
}

Finally, make your project use the updated package by placing the following in your platformio.ini:

platform_packages =
    framework-arduino-megaavr-megatinycore @ file:///Users/mairas/src/SpenceKonde/megaTinyCore/megaavr

Adapt the path as required...

This should be enough to make PIO use the new framework. Additionally, you'll want to get the latest avrdude for its serialupdi greatness. I tried to build it myself but it turned out to be a hassle. Nightly binaries can be downloaded from here: https://nightly.link/avrdudes/avrdude/workflows/build/main (with your own responsibility! Never run random binaries, etc etc!) Copy the uncompressed files to /Users/mairas/.platformio/packages/tool-avrdude-megaavr and PIO should never notice what just happened.

Once you have done all this, you can use platformio.ini definitions such as:

; Chip in use
board = ATtiny1616
; Clock frequency in [Hz]
board_build.f_cpu = 10000000L
; Oscillator type (internal or external)
board_hardware.oscillator = internal

upload_protocol = serialupdi

and it just works!

Additionally, I created the following issue: platformio/platform-atmelmegaavr#53

Go give it thumbs up, and if you want to follow the progress, subscribe to it!

EDIT: Here's a respective issue for avrdude: platformio/platform-atmelmegaavr#46
