Hi Dean,
Welcome to e2e.
We will take a look at your code and provide some inputs. I'd like to ask a couple questions:

Thank you first,
1. Yes, I had DRV2605 Haptics EVM board to experience the effect of motor vibration. but I am not familiar with MSP430 IC and CCS studio;
2. I don't send any signal to the driver, this OC_DETECT flag is not triggered, and some registers above are changed, this OC_DETECT flag is not triggered either. I don't know why!
3. I test the LRA motor on the DRV2605 Haptics EVM board, and it vibrates very well in M0-M4 mode!
Hi, Dean,
Do you see this issue when there's no connected load?
Have you followed the indications of this configuration tool for the best device configuration?

Thank you first,
I had solved the problem of LRA motor viberating in RTP mode by using a new IC of DRV2605L. maybe I confused settings of LRA and ERM registers. I need more times to know the settings and registers of DRV2605L. thank you again!
Best regards,
