Hi! I just got the portenta machine control, but in the IDE when I'm supposed to select a board, there is no selection for the portenta machine control? Which board should I select in the IDE? (the old 1.x or the new 2.x)?
Hi @nineplanets.
In either version of the Arduino IDE, you can select Tools > Board > Arduino Mbed OS Portenta Boards > Portenta H7 (M7 Core) or Tools > Board > Arduino Mbed OS Portenta Boards > Portenta H7 (M7 Core) (depending on which core you want to program).
If you don't have an "Arduino Mbed OS Portenta Boards" item under the Arduino IDE's Tools menu, this means you must install that boards platform. I'll provide instructions:
- Select Tools > Board > Boards Manager from the Arduino IDE menus.
- If you are using Arduino IDE 1.x, wait for the updates to finish.
- Scroll down through the list of boards platforms until you see "Arduino Mbed OS Portenta Boards by Arduino". Click on it.
- Click the Install button.
- Wait for the installation process to finish.
- If you are using Arduino IDE 1.x, click the Close button.
You should now see the boards under the Tools > Board menu of the Arduino IDE.
Please let me know if you have any questions or problems while following those instructions.
Thank you @ptillisch! 
You are welcome. I'm glad if I was able to be of assistance.
