Hello,

Can you try to perform a firmware update on the faulty board by going through the Sensing Solutions EVM GUI? Additional instructions on updating the firmware are in the EVM user's guide section 1.2.9.

Also, how does the EVM show in the PC's device manager?

Thank you,

Justin Beigel

Hello,

You may have to reinstall the driver for that EVM. You can do this by reinstalling the GUI as administrator or just uninstalling and reinstalling the driver. More information on that can be found in the following E2E post: https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/716036/ldc1000evm-msp430-usb-driver-unknown

Hello Frank,

Sorry you are still having issues. Can you confirm if the non-working EVM is still showing as "MSP430-USB Example"?

Thank you,

Hello Frank,

If the EVM is still showing the "MSP430-USB Example" prompt for the driver, then the USB driver didn't successfully change with the SW reinstall. Try manually changing the driver by going through the device manager. The EVM driver is located in path C:\ti\Sensing Solutions EVM GUI-(version #)\EVM Driver by default. Where (version #) is replaced with the version number of the sensing solution GUI. Version 1.10.0 is the most current version. The driver name is evm.inf.

Best Regards,

Hello Frank,

You could try re-flashing the EVM by putting it into BSL mode and flashing it through the Python firmware upgrader. Here are some more detailed instructions for that:

Put the EVM into BSL mode by shorting C6 and R40 together before powering up the EVM
Once shorted, connect the EVM to the PC. Once the EVM powers on, it should go into BSL mode.
Download the Python Firmware Upgrader tool: Python_Firmware_Upgrader.zip
Run Python_Firmware_UpgraderGUI.exe
If the device is connected and in BSL mode the screen should display "ready..."
If this is not the case, ensure that the device is in BSL mode (no LEDs will be on) and click File -> Rescan HID Bus
Choose File -> Open User Firmware and navigate to the proper EVM firmware file
The Sensing Solutions GUI comes with the most up to date firmware files in the following folder path: C:\ti\Sensing Solutions EVM GUI-1.10.0\EVM Firmware.
When successfully completed the screen should read "Programming: OK"

At this point, the EVM should be recognized by the Sensing Solutions GUI and connect properly. Between reflashing the EVM and manually updating the USB driver, the issue should be resolved. If you still have issues, it is possible that the board is damaged.

Justin Beigel
