CCS/BOOST-DRV8711: BOOST-DRV8711 GUI problem

Hi Zsolt,

The MSP430G2553 is not being recognized. Is the launchpad COM4? Please check the com ports and confirm there are no other similar USB devices.

Have you re-tried per the user guide:

After a successful launch of the BOOST-DRV8711_GUIvX.X.exe, Figure 11 pops up. It may take a small period of time before the GUI connects and the GUI Widgets populate (red X's appear on the widgets while the GUI is connecting). If the GUI does not load after a few minutes (the X’s disappear), a connection issue may have occurred and TI recommends restarting the application.

Hi Rick,

Your quick response is really appreciated.

Well, yes, it has been checked, the COM4 is correct, this is the only COM port, also in the windows device manager.

Also, the GUI has been restarted several times, without any change.

The Launchpad and the micro is working. I have tried a very basic LED blinking sample program from Energia, without problem.

I tried to use CCS version 5.5.0 and 7.3.0 also to build the DRV8711 sample project to see if there is any difference, but the symptoms are the same.

One more thing. I have realized a warning in the CCS IDE.

Please see below. I'm not sure if it is a problem, or not, or connected to the GUI issue.

Thank you.

Hi Zsolt,

Two more items to check before we will have to investigate more thoroughly.

1) Did you re-configure the jumpers per the user guide:

For the MSP-EXP430G2 LaunchPad, remove the P1.0 and P1.6 (LED1 and LED2) jumpers for correct
operation of the POT and SDO signals of the BoosterPack. The TXD and RXD jumpers should be aligned
horizontally (black rectangles in Figure 4) for operation of the hardware UART with a software application

2) Are you using version 5.5 or greater of GUI Composer Runtime? Anything lower does not support the MSP430.

Hi,

Yes, the jumpers are configured according to the user guide.

I downloaded and installed now the latest version of GUI Composer.

Now, the situation slightly better. GUI identify the controller.

However I got some error message. Please see below:

Thank you.

Hi Zsolt,

Another couple of question:

After loading the code is loaded into CCS, the mcu is not running until either F8 is pressed or the LaunchPad power is cycled.
What did you do after closing CCS? Can you disconnect and reconnect the USB to cycle power?

Hi Rick,

Yes, I have tried power cycle the mcu by disconnecting the usb and connecting it again.

Also I tried push the reset button.

No change.

Based on the screenshot i previously sent you it seems the mcu try to send some characters to the GUI, but it expect something different. "expected 0xc2, received 0x2" Right?

Thank you,

Zsolt

Hi Zsolt,

I found one more clue I missed. Please see the link:e2e.ti.com/.../622807

Another possible cause is using a different compiler version than the original. This could cause some variables to move, and affect operation.

The compiler version should be v.4.1.7

Rick, yes I also realized that CCS claims the project was created by using the v.4.1.7 compiler.
Therefore I installed this version.
Unfortunately it did not help.

Hi Zsolt,

Did you try both methods of configuring the LaunchPad? If you tried method 2 first, please re-download the software zip file and try method 1.

If that does not work, would you please send the following files from the debug folder of CCS after compilation:
BOOST-DRV8711_FIRMWAREv1.0.out
BOOST-DRV8711_FIRMWAREv1.0.map
BOOST-DRV8711_FIRMWAREv1.0_linkInfo.xml

Hi Rick,

If I try method 1, i got two errors.

The first, when I try to connect to the target (Fig. 8 in the instruction)

Please see below:

The second error I got, when I try to load the program, according to Fig. 9.

Please see below:

So this way, practically no compilation.

The files are the original ones.

Please see attached.

Thanks for your continuous support.

Hi Rick,

Is there any additional ideas? How can I go further, how can I resolve the issues experienced by using method 1?

Thanks,

Zsolt
