    Is the device in shutdown, have you tried forcing it to exit shutdown with the TS2 pin tied to GND? Can you provide any other pin status of the part?

    some additional troubleshooting steps from Section 8.6 of the FAQ.

    8.6 Why is BQStudio not detecting to the BQ769x2EVM?

    To debug connection issues to BQStudio, first verify that you are running the newest version of BQStudio, which is the BQSTUDIO-TEST file. Then proceed to follow the steps from the Quick Start Section of the EVM
    1. Connect a power supply between BAT+ and BAT-.
    2. Connect your computer via a USB cable to the EVM. Three green LEDs are turn on when the computer is connected.
    3. Check BQStudio’s Dashboard to verify that the on-board microntroller is connected and which firmware is using.
    4. Only have one EVM connected to your laptop for each unique window of BQStudio being used.
