CCS/BOOSTXL-DRV8323RS: Unable to run Sensorless BLDC using the DRV8323RS

Tool/software: Code Composer Studio

Hi,

I am currently using DRV8323RS with MSP430F5529 to run a sensorless BLDC motor.

I am trying to create a standalone program without the use of GUI.

With DRV8323RS, I downloaded the source code for sensored and sensorless for CCS.

I managed to create a program for sensored motor and is able to run the sensored BLDC motor

However, when I tried to replicate the codes for the sensorless BLDC motor, the motor doesn't turn on. I measured the voltage at the high and low gates and noticed that GLA, GLB, GLC is reading some voltage (~ 10Vdc) while GHA, GHB, GHC is reading 0V. I believe that is incorrect.

Is it possible to have a look at my codes? If yes, I can send you my codes in a separate email if necessary.

Please advice.

Appreciate your help.

Thanks,

Thena
