Cannot install 2 Attiny Cores on PC

[mikedb]

Hi Everyone.

Using Attiny85

http://digistump.com/package_digistump_index.json

First I installed the Digistump core with the Board Manager .
I can select the Core in Boards and upload the Start/Blink example.
I can change the Blink speed of the LED.

(http://drazzy.com/package_drazzy.com_index.json)

When I try to Install the Core from DrAzzy with the Board Manager .
I get a error that the Micronucleus file already exists and cannot be exstracted.
Then the Installation stops.
Is it possible to have both Cores on the PC.

Thanks.

i install a core to get possibility to upload my FW in the chip.
why someone would need more at same time?

[mikedb]

The DrAzzy Core only got the Temperature Example.

The Digispark Core has a lot of examples try the Digispark_OLED it does not compile with the DrAzzy core.

Hi @mikedb

I get a error that the Micronucleus file already exists and cannot be exstracted.

Please post the full and exact text of the error message in a reply here.

Please also tell us which version of Arduino IDE you are using (e.g., "2.0.1")? The version is shown on the window title bar and also in the Help > About dialog.

I don't have any reason to think the problem is specific to a version of Arduino IDE, but the information might be useful in the end.

@mikedb

Is it possible to have both Cores on the PC.

Definitely. I just installed both of them to be certain.

[mikedb]

This is the error but I cannot Copy or Copy to Forum.

@mikedb

Micronucleus file already exists and cannot be exstracted.

My Aduino version is 1.8.19

I did solve some of the problems.
I downloaded the zip file and paste the exstracted folder in Arduino15/hardware but the core did not show up in the Board selection.

Then I installed with the Board Manager and got the error.
I deleted the unzipped folder from Arduino/hardware and then the installation worked.

But only one core shows up in the Board Selection menu.

You must install it into a very specific location under that folder. Arduino15/hardware is not the correct location.

@mikedb

But only one core shows up in the Board Selection menu.

Something you should note is that Arduino IDE 1.8.19 only recognizes "cores" that are installed under the Arduino15 folder when the "Additional Boards Manager URL" for that "core" is present in the "Additional Boards Manager URLs" field of the Arduino IDE "Preferences" dialog. Even if you have the "core" installed in the correct location under Arduino15, it won't show up in the Tools > Board menu of Arduino IDE without the correct URL in the preferences.

You can add multiple URLs to your preferences by separating them with commas:

http://digistump.com/package_digistump_index.json,http://drazzy.com/package_drazzy.com_index.json

[mikedb]

Thanks this makes a lot of sense
The last one I install is alwys the only one that I can see , because the URL Link is still in the Preference dialog.
I will test this later and report back.

[mikedb]

I have both URL,s in the preference dialog but only the last Core that I installed shows up in the Board selection.

Both Cores is installed with the Board Manager.

This is the path of the installed Cores.

Something I didn't mention is that you also need to open the Arduino IDE Boards Manager once while those URLs are in your preferences. This causes the JSON file that is the target of the URL to be downloaded to your computer.

Try this:

1. Select Tools > Board > Boards Manager from the Arduino IDE menus.
   A "Boards Manager" dialog will appear.
2. Wait for the updates to finish, as shown by the messages printed at the bottom of the "Boards Manager" dialog.
3. Click the Close button on the "Boards Manager" dialog.

After performing those instructions, check to see whether both "cores" are shown under the Tools > Board menu in Arduino IDE. Hopefully all will be well now.

[mikedb]

The tricks of the trade.

I followed your steps and yes now both Cores is available.

Thanks a lot.

[ptillisch]

You are welcome. I'm glad it is working now.

We identified this behavior of not recognizing the cores when the URL or JSON file was missing as a poor user experienced and changed the behavior in Arduino IDE 2.x. Arduino IDE 2.x will always recognize the installed cores even when you don't have the URL in your preferences, or if the JSON file went missing. So even though there is some pain when using the older IDE version, at least hopefully our future present is a bit more happy.
