ATTINYCORE on IDE 2.2.1

mike_trantham · October 27, 2023, 4:34pm

I added the URL to preferences, no error messages, but ATTINYCORE does not show up in the board manager. Have I forgotten a step?

ptillisch · October 27, 2023, 4:41pm

Hi @mike_trantham. This is caused by a bug in Arduino CLI versions 0.34.0 - 0.34.2, which also affects Arduino IDE versions 2.2.0 - 2.2.1:

github.com/arduino/arduino-cli

Package index filename is truncated if it contains `.`

conclusion: resolved topic: code type: imperfection

### Describe the problem If the filename of a package index contains the char…acter `.`, Arduino CLI truncates the downloaded filename ### To reproduce ```text $ arduino-cli version arduino-cli.exe Version: git-snapshot Commit: 6aa1be03 Date: 2023-09-28T08:02:22Z $ export ARDUINO_DIRECTORIES_DATA="/tmp/arduino-cli-directories/data" # Use a throwaway directories.data for the demo $ arduino-cli --additional-urls http://drazzy.com/package_drazzy.com_index.json core update-index [...] Downloading index: package_drazzy.com_index.json downloaded Error initializing instance: Loading index file: loading json index file C:\Users\per\AppData\Local\Temp\arduino-cli-directories\data\package_drazzy.com_index.json: open C:\Users\per\AppData\Local\Temp\arduino-cli-directories\data\package_drazzy.com_index.json: The system cannot find the file specified.

Invalid argument passed: Platform 'ATTinyCore:avr' not found ``` 🐛 The downloaded package index was named `package_drazzy.json` instead of the correct name `package_drazzy.com_index.json` 🐛 The platforms from the package index can't be installed because the truncation caused the file to no longer have the [required filename format](https://arduino.github.io/arduino-cli/dev/package_index_json-specification/#naming-of-the-json-index-file) (`package_<differentiator>_index.json`). ### Expected behavior The filenames of package index files are not changed on download. ### Arduino CLI version 6aa1be03 ### Operating system - Windows - Linux ### Operating system version - Windows 11 - Ubuntu 22.04 ### Additional context I bisected the regression to 82e6f5d7e77f21f5894802aaca5ee5aa24a60bd1 (doesn't occur when using the build from the previous commit 1877431762fe31519d8c51de0df9e4e018c475a3). --- The use of a full domain name in the package index filename is explicitly recommended in the Arduino Package Index Specification: https://arduino.github.io/arduino-cli/dev/package_index_json-specification/#naming-of-the-json-index-file > We suggest using a domain name owned by the packager. For example: > > `package_arduino.cc_index.json` --- Originally reported at https://github.com/SpenceKonde/ATTinyCore/issues/803#issuecomment-1738280090 #### Additional reports - https://github.com/SpenceKonde/megaTinyCore/issues/1005 - https://github.com/SpenceKonde/ATTinyCore/issues/802 #### Related - https://github.com/adafruit/ci-arduino/pull/163 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=) - [X] I verified the problem still occurs when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds) - [X] My report contains all necessary details

I apologize for any inconvenience this has caused.

The bug has already been fixed, but Arduino IDE is still using the version of Arduino CLI with the bug so the fix is not yet available to Arduino IDE users (updating the Arduino CLI dependency is in progress now).

I'll provide instructions you can follow for a workaround to the bug:

Select File > Quit from the Arduino IDE menus if it is running.
Open the following folder in your file manager program (e.g., Windows File Explorer):
- If you are using Linux:
```
/home/<username>/.arduino15/
```
  (Where <username> is your Linux username)
  The .arduino15 folder may be hidden by default in your file manager and terminal.
- If you are using macOS:
```
/Users/<username>/Library/Arduino15/
```
  (Where <username> is your macOS username)
  The Library folder is hidden by default. You can make it visible by pressing the Command+Shift+. keyboard shortcut.

If you are using Windows:
```
C:\Users\<username>\AppData\Local\Arduino15\
```
(Where <username> is your Windows username)
If looking for it with your file manager or command line, note that the  folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".

You will see a file named package_drazzy.json in that folder. Rename it to package_drazzy.com_index.json.

Now start Arduino IDE again. You should now see ATTinyCore (as well as the other SpenceKonde/DrAzzy) platforms listed in Boards Manager and be able to install it as expected.

Thanks @ptillisch , unfortunately now I get:

ledsyn · October 27, 2023, 7:01pm

@ptillisch Maybe update expects to find the old name, package_drazzy.json Perhaps a shortcut package_drazzy.json pointing to package_drazzy.com_index.json would work.

ptillisch · October 28, 2023, 8:40am

This is caused by a problem with the SSL configuration of the azduino.com website from which the ATTinyCore:micronucleus@2.5-azd1b tool dependency of ATTinyCore is downloaded:

$ curl https://azduino.com

curl: (35) schannel: next InitializeSecurityContext failed: SEC_E_CERT_EXPIRED (0x80090328) - The received certificate has expired.

It affects everyone universally rather than being a problem specific to your own system. It has been reported to DrAzzy/SpenceKonde here:

The workaround will be to manually download the tool archive (the archive download URLs can be extracted from the package index file) and then place it in the Boards Manager download cache. Arduino IDE checks for the file in the cache before attempting to download it from the Internet, so if you have manually placed the file in that location, you avoid the problematic download that causes the ATTinyCore installation to fail.

1. Download the `ATTinyCore:micronucleus@2.5-azd1b` Archive File

Unfortunately you will likely find that attempting to download this file via the browser is not very user friendly. For security reasons, the browser will try to strongly discourage from downloading it and you will have to make some efforts to overcome its resistance.

This is the download URL:

If you are using Windows:

http://azduino.com/bin/micronucleus/micronucleus-cli-2.5-azd1b-x86_64-mingw32.zip

If you are using Linux x86:

http://azduino.com/bin/micronucleus/micronucleus-cli-2.5-azd1-x86_64-linux-gnu.tar.bz2

If you are using Linux ARM:

http://azduino.com/bin/micronucleus/micronucleus-cli-2.5-azd1-arm-linux-gnueabihf.tar.bz2

If you are using macOS:

http://azduino.com/bin/micronucleus/micronucleus-cli-2.5-azd1-x86_64-apple-darwin.tar.bz2

2. Add the Downloaded File to the Boards Manager Cache

After you manage to download the file, copy it to the following folder:

If you are using Windows:

C:\Users\<username>\AppData\Local\Arduino15\staging\packages\

(Where <username> is your Windows username)

If you are using Linux:

/home/<username>/.arduino15/staging/packages/

(Where <username> is your Linux username)

If you are using macOS:

/Users/<username>/Library/Arduino15/staging/packages/

(Where <username> is your macOS username)

3. Install ATTinyCore

Now try installing ATTinyCore via the Arduino IDE Boards Manager again. The installation should now be successful.

mike_trantham · October 30, 2023, 2:37pm

Thanks! I appreciate all the effort and expertise that went into this solution.

ptillisch · October 30, 2023, 4:05pm

You are welcome. I'm glad if I was able to be of assistance.

March 1st 2024. This problem persist. http://azduino.com/ link is broken, or site is down. I've been trying to find the micronucleus-cli-2.5-azd1b-x86_64-mingw32.zip file but no luck.
Fresh Arduino IDE fails to install Attiny Core due to this broken link.

ptillisch · March 2, 2024, 7:24am

That is unfortunate. The entire site is down so this is a different situation from before where the files were available, but just not via SSL.

I have a copy of the file you need:

micronucleus-cli-2.5-azd1b-x86_64-mingw32.zip (1.1 MB)

You can follow the "2. Add the Downloaded File to the Boards Manager Cache" instructions from my previous reply, except using the file downloaded from the attachment.

You should be very wary of running an executable downloaded from a random forum post attachment. You can verify the file above is the same as the one previously available from azduino.com by getting the SHA-256 checksum of the downloaded file by opening a PowerShell terminal in the folder where you downloaded the ZIP file and then running this command:

Get-FileHash -Path micronucleus-cli-2.5-azd1b-x86_64-mingw32.zip -Algorithm SHA256

After that, compare it to the checksum for the file you can find by opening the ATTinyCore "Additional Boards Manager URLs" URL in your browser and then searching the page for "micronucleus-cli-2.5-azd1b-x86_64-mingw32.zip". The URL is available from the ATTinyCore installation instructions:

github.com

SpenceKonde/ATTinyCore/blob/v2.0.0-devThis-is-the-head-submit-PRs-against-this/Installation.md

# Supported IDE versions

ATtinyCore (Universal) works with all versions of the official IDE (from arduino.cc ) from version 1.6.11 onwards (we have dropped support for versions prior to the fixes in 1.6.11 in 2.0.0), and it is known that manual installation would never work on older versions because they don't come with a toolchain that supports LTO, and the process of manually updating the toolchain is non-trivial. Plus - those versions are old as the hills now). Version 1.8.13 or newer is recommended. Version 1.9.x versions mostly did not work, however.  Version 2.0.4 might work, 2.0.3 does not.

Note also that version 1.7.x versions are from the "other" arduino when arduino.cc and arduino.org got into a some sort of dustup, and arduino.org forked the IDE and increased the minor version to make theirs look newer. No 1.7.x version is supported.

## Boards Manager Installation

This core can be installed using the boards manager. The boards manager URL is:

`http://drazzy.com/package_drazzy.com_index.json`

1. File->Preferences on a PC, or Arduino->Preferences on a Mac, enter the above URL in "Additional Boards Manager URLs
2. Tools -> Boards -> Boards Manager...
3. Select "ATTinyCore by Spence Konde" and click "Install".

## Manual Installation

Option 1: Download the .zip, extract, and place in the hardware folder inside your sketchbook folder (if there is no hardware folder, create it). You can find/set the location of the sketchbook folder in the Arduino IDE at File > Preferences -> Sketchbook location.

This file has been truncated. show original

The Arduino IDE Boards Manager actually compares the checksum of the file from the Boards Manager cache against the file in the package index and only uses the file if the checksums match.

I checked on my Linux and macOS machines but unfortunately I didn't have the file cached on those machines so we only have the Windows file as of now and I didn't find another source for the files. If anyone needs to install ATTinyCore on other operating systems, you can post on the forum and hope one of the other forum helpers can provide the file.

m4r0labs · March 2, 2024, 3:15pm

Thank you very much @ptillisch , due to my bad luck I use Linux, open a new thread in case someone has the file

ptillisch · March 3, 2024, 2:11pm

Hopefully one of the forum helpers will have this file. For the forum helpers, you should have it on your computer if you ever used Arduino Boards Manager to install ATTinyCore version 1.5.2.

The file would be located at this path:

/home/<username>/.arduino15/staging/packages/micronucleus-cli-2.5-azd1-x86_64-linux-gnu.tar.bz2

(Where <username> is your Linux username)

(i.e., ~/.arduino15/)

The .arduino15 folder may be hidden by default in your file manager and terminal.

sterretje · March 3, 2024, 3:32pm

I had to install an older version (ATtinyCore 1.4.1) due to an error related to avrdude; so I hope that this one helps; strip of the .zip (added because the forum does not allow to upload .tar.gz).

micronucleus-2.0a4-linux32.tar.gz.zip (21.4 KB)

And the error that I get when trying to install the latest version of ATtinyCore:

 Tool avrdude is not available for your operating system.
java.lang.RuntimeException: java.lang.Exception: Tool avrdude is not available for your operating system.

In case it's relevant, this is a 32bit Linux and a portable install of IDE 1.8.19.

ptillisch · March 3, 2024, 4:07pm

It is. The DrAzzy package index file contains host definitions for 32-bit and 64-bit Linux. For example, here it is for ATTinyCore:micronucleus@2.0a4:

          "name": "micronucleus",

            },
            {

              "archiveFileName": "micronucleus-2.0a4-linux64.tar.gz",
              "url": "https://github.com/digistump/DigistumpArduino/releases/download/1.6.5a/micronucleus-2.0a4-linux64.tar.gz",
              "checksum": "SHA-256:1F545C0BB60E85A604901C2D7044772AC91776594C209C571DFEDAD4A70195B8",
              "size": "22874"
            }
          ]
        }

When installing ATTinyCore on a 64-bit Linux machine, Arduino IDE will look for the archive file for the 64-version of the tool in the staging folder and then if it is not found, will attempt to download it from azduino.com (which will cause the installation to fail even if the archive for the 32-bit version of the tool was present in the staging folder).

The information I provided in post 11 assumes that @m4r0labs is using 64-bit Linux on an x86 machine. If they are using 32-bit machine then the information I provided is not relevant.

m4r0labs · March 5, 2024, 12:21am

Thanks @ptillisch , also the repository azduino is working again

ptillisch · March 5, 2024, 6:05am

Great news! Thanks for taking the time to post an update.

To make it clear to anyone later reading this thread: this means the workaround we discussed starting from post #9 is no longer necessary. Everyone can now use the standard ATTinyCore installation procedure.

basti93 · June 7, 2024, 12:03pm

Hi at all,

I want to install ATTinyCore in my Arduino IDE 2.3.2 but a error message comes up and I can't install it.

Error message: Some indexes could not be updated. failed to verify certificate: x509: certificate has expired or is not yet valid:

Thank you for your help.
