I will make a video for Mac users soon.
This is the tool, which you have to give permission for in the Security & Privacy preferences pane. Once you do, you just open a Terminal app and run these commands to update the Tone2 Pro’s MCU or XMOS respectively.
Update MCU:
/bin/bash -c "$(curl -fsSL https://dl.khadas.com/Firmware/Tone2/upgrade_mcu.sh)"
Update XMOS:
/bin/bash -c "$(curl -fsSL https://dl.khadas.com/Firmware/Tone2/upgrade_dfu.sh)"
If you have more questions about upgrading the firmware for either the XMOS or MCU, please continue the discussion in this thread: Tone2 Pro - Firmware v1.2 + MCU Update
