Not able to update MCU

Continuing the discussion from Tone2 Pro - Firmware v1.2 + MCU Update:

Hi,

I have tone 2 pro with 1.0 firmware and macbook pro. I strictly followed the instructions and couldn’t make the MCU update.

If I understand the log correctly automated link to the file Tone2_Pro_MCU_Firmware_210417.zip is not working. File nr. 210417 is not to be found.

Please advise how to update MCU.

Kind regards, Gregor

Hi Gregor_bogataj,
From your upgrade log, found that::

  • Your software was install ok
  • Your ST-Link V2 version is ok
  • You are right, the script on the web page has not been updated(will fixup this later), the update is as follows:
/bin/bash -c "$(curl -fsSL https://dl.khadas.com/products/tone2/firmware/tone2_pro/mcu/upgrade_mcu.sh)"

I checked the script again and it has issues with libusb installation. This problem can be solved simply. This error message was not found through your log files. You may have solved it.

  • The SWIM connection seem doesn’t right. I need your help to take a picture of the detailed connection diagram for me to see. When taking the picture, be careful to take a picture of the electrical network signal to facilitate troubleshooting.

  • Another possibility is that when updating the firmware, the connection is unstable. You could try to slightly press the pin header connection with your hands to allow the electrical signals to fully contact.
