Unable to install M2 on IDE

I installed, removed and reinstalled everything but I always get:

Board m2 (platform sam, package macchina) is unknown
Error compiling for board Macchina M2.

I installed Arduino IDE 1.8.5,
https://macchina.cc/package_macchina_index.json,
Arduino SAM Boards (32-bit ARM Cortex-M3) by Arduino 1.6.11
Macchina SAM Boards (Install Arduino SAM Boards first) by Macchina 0.2.1

I choose Macchina M2 (or should it be the beta??) on COM5 (Bossa Program Port)

If I click on “Get board info” I have:
BN: Unknown board
VID: 03EB
PID: 6124
SN: Upload any sketch to obtain it

Where am I wrong?

Felix, Sorry you are running into issues here. I ran into a similar problem when re-installing IDE on another machine a while back. I found this post to be useful.

There are some “hidden” Arduino files (Arduino15) you should delete before reinstalling Arduino IDE.

Also, only select “Beta” if you were one of the 100 developers who received a Beta board several months ago.

Once you try this again, run the “Blink” example and let us know if this works for you.

Thank you!! It worked erasing Arduino15 folder!

Thanks

I had this issue when the macchina files got changed/renamed. deleted them and install the new ones worked.
