$ arduino-cli compile -b "LGT8fx Boards:avr:328:clock=16MHz:variant=modelP" test
Error during build: incorrect FQBN: invalid fqbn: LGT8fx Boards:avr:328:clock=16MHz:variant=modelP

$ arduino-cli board attach "LGT8fx Boards:avr:328:clock=16MHz:variant=modelP" test
Attach board error: invalid Device URL format: parse "serial://LGT8fx Boards:avr:328:clock=16MHz:variant=modelP": invalid port ":variant=modelP" after host

Getting the error above when trying to set two options (clock and variant in this case) for the board.

Expected behavior

Ability to set multiple board options.

Environment

• CLI version (output of arduino-cli version): arduino-cli Version: 0.9.0-arch Commit: e4d02b4
• OS and platform: ArchLinux with kernel 5.5.13-arch1-1

Hi @ilgiznurgaliev, thanks for reaching out!

Could you please try to separate with comma the additional options?
Try something like arduino-cli compile -b "LGT8fx Boards:avr:328:clock=16MHz,variant=modelP" test

We understand that this is a feature not perfectly documented, would you be so nice to open a PR in our FAQ documentation section to help also other users that will encouter your same issue?

Happy coding!

Hi Roberto.

Works as expected with commas.
PR #638 has been created to update FAQ.

Thank you very much.
