You can save your project into a GitHub repository from MakeCode and import it later on.

@peli , sir i want to create a new custom block and custom board.

compilerServiceVariant , what is this , and waht i have to update?

I’m using the Arduino nano board but can’t find pxt-common-packages.
Let me explain you once what I’m trying to do. I have a custom board based on Arduino nano and trying to have it programme it and simulate it with makecode. For that I need to add my board, and add new blocks. I couldn’t find the resources to use pre-configured files for the same in pxt maker. Kindly help me with the same.

Do you have a repo somewhere?
