Bug Report

Current behavior

arduino-cli upload -vb esp32:esp32:esp32:baud=115200 -p /dev/ttyUSB4 myDualCore

Error during Upload: incorrect FQBN: getting build properties for board esp32:esp32:esp32: invalid option 'baud'

Expected behavior

Expected the baud rate option to be accepted and used for upload.

Environment

• CLI version (output of arduino-cli version): arduino-cli Version: 0.11.0 Commit: 0296f4d
• OS and platform: Linud 5.3.0-62-generic Ubuntu 18.04.4 LTS

Additional context

I only have a problem with ESP32 boards which want to upload at 921600. I have no problem when set baud rate for an ESP8266 board.
