minicore and compile options

[a7hybnj2]

I managed to install minicore but I don't see the options needed to compile correctly.

Board:
Bootloader:
Clock:
BOD:
Compiler:
Variant:

It sounds like a duplicate of #138

In that issue, I have provided instructions for how you can determine the FQBN for any board. This is the solution I would recommend for you:

My current approach in the case of boards with custom Tools menus is to do a compilation in the Arduino IDE for the specific board configuration I want with File > Preferences > Show verbose output during: compilation enabled, and then copy the FQBN from the first line of the output in the black console window at the bottom of the Arduino IDE window. Quite crude, but it seems the fastest and least error-prone solution for me.

If I misunderstood and you are reporting a bug in arduino-cli or submitting a feature request here, then please provide more details and I'll be happy to re-open the issue. If you need assistance using MiniCore with arduino-cli, please post on the Arduino Forum and we'll help you out over there.

@per1234 Thanks!
-fqbn=MiniCore:avr:328:bootloader=false,variant=modelP,BOD=2v7,LTO=Os,clock=16MHz_external
I guess I will have to type that in every time!? yikes.

Since this is the first result in Google for "arduino-cli minicore",

• To see a list of all boards you have installed with their FQBN:

arduino-cli board listall

• To see the available options for a board you can use this command:

arduino-cli board -b MiniCore:avr:8 details

• To set the default options for a sketch:

arduino-cli board attach -b MiniCore:avr:8:bootloader=no_bootloader,BOD=4v0,LTO=Os_flto,clock=8MHz_internal "PATH\TO\PROJECT" --port COM3

Now every time you compile or upload these settings will be used by default, unless you override them. So you can simply do arduino-cli compile with no options.
