DRV8308EVM no communication between Gui and MSP430.

Other Parts Discussed in Thread: DRV8308EVM, MSP-FET

Good day,

I wanted to do some testing with the DRV8308EVM, but the GUI will not load without installing Gui composer.

And when GUI composer is installed it the GUI see's the USB to Uart chip from FTDI but it will not show the used processor.

After this point its clear that there is no communication between DRV8308EVM and the GUI. 

We made a interface the board with a MSP-FET programmer to program the MSP. We programmed with the firmware delivered with the GUIv1.2 file but no luck.

Did we miss a library for Uart communication?? Also tried to make it work with Linux but faild to launch GUI composer after install...

    Hi Vincent,

    The GUI was designed for windows. It may not work with Linux.

    Can you provide screen captures of the GUI at the few points it does not match the user's guide?

    Hello,

    I only referenced too Linux because i wanted to try something different after 8 hours of tinkering.

    Here is the screen i am stuck in. 1 Board is reprogrammed with the firmware that was delivered with the GUI and the other board is still the default firmware in the MSP.

    This problem is on 3 computers with Windows 7 and 2 DRV8308EVM boards... Mine guess is that Gui composser is missing some library for Uart.... But at this point i dont know where to start searching.

    Hi Vincent,

    The red Xs indicate there is no communication between the GUI and the MSP430.

    Please make sure you have installed GuiComposer Runtime version 5.5 or higher. Link to GUI Composer Runtime is HERE. Earlier versions do not have support for the UART I/F of the MSP430. This is documented in the User guide.

    Also, please note this POST to determine if the proper firmware is loaded after the Xs disappear. This post will allow you to determine if the correct firmware is installed.
