Hi Zhiyu,

If the MCU STATUS LED is not blinking try performing a firmware reset using the push button S1 with jumper J27 in 1-2 RST position.

Best,

David

Hey Zhiyu,

Please see this FAQ: [FAQ] Why won't my Motor Driver EVM connect to the GUI?

In this case please confirm you 1. Plug in Micro-USB to PC 2. Turn on VM power supply >5V. Maybe wiggle the micro-USB connector in case it is loose or not making good connection?

Make sure the jumpers are installed here:

Then in the GUI do File, Program Device to flash latest firmware onto the EVM

Best,

Jacob

Hey Zhiyu,

Can you probe the 3.3V test point to see if there is 3.3V?

For flashing the EZFET firmware onto the top MDP430F5528, if you have a MSP-FET see the attached info:

7651.Programming a blank MSP430F5528 in the Brushed and Stepper motor driver EVMs.zip

Got it from this post: https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1311649/drv8262evm-unable-to-recognize-usb-port-after-fw-update/4984304#4984304 I am not sure why we are having issues updating only this EVM.

Best,

Jacob
