Tool/software: Code Composer Studio

After so much attempts now successfully installed all driver and COM Ports just like below. I have downloaded the .OUT file in the folder of E:\ccs\DRV8350x_EVM_BLDC_FW_1.0.0\DRV835X_MSP430F5529_Trapezoidal_Sensored_BLDC\Debug, But as I tried to drive the motor use the GUI OF DRV8350x EVM, when I enabled the drv8350H device,

it indicate unknow error and NFault led light is on. what's wrong?

Followed is my design schematic.

I have also tried to use the Uniflash tool to download the pre built .out file which is available in the the package of DRV8350x_EVM_BLDC_FW_1.0.0. But it still can not spin the motor.

How can I further dubug my device?

Scalery,

The GUI and OUT files are designed to work with the EVM and unfortunately it is difficult to support development using our toolset and a custom board.

There are three threads about this exact same question so I am closing this thread.

Hello Adam,

Thanks for your reply, But I used the TI reference design which is very supported in Ti.

About NFault error, How can I debug that, I just didn't use the SPI interface.
