DRV8329AEVM: Missing Identifier: ISEN_BIDIRECTIONAL, it cannot be found in target program's symbols after Hardware connect in DRV8329AEVM GUI

Part Number: DRV8329AEVM
Other Parts Discussed in Thread: LAUNCHXL-F280049C,

Hello, 

I am using DRV8329A_EVM_GUI (ti.com) with DRV8329A EVM and LAUNCHXL-F280049C and I have problem that program is halted with message "(Suspended-SW Breakpoint)" in CCS.

I ensure Lauchpad is powered by DRV8329AEVM depopulate the Shunt JP1, JP2, JP3 of the Launchxl-f280049c and I applied power to DRV8329AEVM with 24Vdc.

After hardware connection(to DRV8329A and Launchpad F280049C) from GUI , it displays "Hardware Connected" but in the left bottom corner there is small x mark and it displays "Missing Identifier: ISEN_BIDIRECTIONAL, it cannot be found in target program's symbols" and program doesn't run and seems halted.

For another trial, I tried to download the TI provided example software "DRV8329AEVM_Sensored_Trapezoidal_Firmware" but after download completion with XDS110, I started application but it halted with message "(Suspended -SW Breakpoint. A reset occurred on the target). After detaching DRV8329A EVM and with only Launchpad F280049C, it runs well.

Would you please lt me know how can I try to solve this ?

Thank you in advance.

    Hi Hansoo,

    I discussed this with my coworker and he said that he is aware of the x mark that displays "Missing Identifier: ISEN_BIDIRECTIONAL, it cannot be found in target program's symbols". He said that it shouldn't effect the ability to use the GUI. You need to set Output Enable and then Set the desired Duty Cycle or set Potentiometer Enable and use the on board potentiometer to control the speed of the motor. You can watch the getting started video at the bottom of the DRV8329AEVM page or refer to the User's Guide if you still have issues operating the motor with the GUI.

    Thank you for the explanation.

    I found out that the halt problem came from motor hall sensor circuit power shortage.

    I changed hall power selection jumper  in EVM to EXT from AVDD and it works. It seems the motor hall sensor circuit gets much power form EVM and it arise instant shortage of power to the CPU to halt program. It was resolved by supplying hall sensor circuit power from external power supplier.

    Thanks.
