Hi team,

In accordance with instruction of LMK05318B Wizard, my customer clicked "Write All Registers".

However, below error massage showed up. What should he check?

    Hi Shota,

    Please confirm these steps:

    1. Step 1: Go to USB communications  
    2. Step 2: Go to Interface  
    3. Step 3: Select USB2ANY
    4. Step 4: Ensure the USB2ANY device (this is an MSP430 on-board the LMK05318BEVM) is detected. You should see a unique serial number show up.
    5. Step 5: Once a USB2ANY device is selected, scan the I2C bus.
      1. If you get "no device found" at this stage, make sure the EVM is receiving power. Probe the VDD and VDDO pins.
    6. Step 6: Once the I2C address is detected, I2C communication between the LMK device and USB2ANY/computer is confirmed. Proceed to click Write All Registers or load the desired .tcs file.

    Please let me know if there are issues along any of the above steps.

    Regards,

    Jennifer
