MCT8329A: EEPROM Writing issue

Hi all,

I am using MCT8329EVM for testing. I have constant issue with writing EEPROM using the GUI provide (all version V1.0.0, V1.1.0, V1.1.1)

I often have issues that the EEPROM is not written after hit "WRITE TO EEPROM" even the GUI prompted the "EEPROM write_cmd successful". 

I am sure the driver is connected properly through I2C as I was able to tune the driver and set the register, and confirm that the motor behaved as set. 

According to the datasheet: 
MCT8329A allows EEPROM write and read operations only when the motor is not spinning.

So I am sure about this as well.

Other board setting:

-Dirver is on brake mode 
- BrakePin - Low
- Speed/wake pin - 1V -> using this pin to set analog speed
- DRVOFF - Low



The procedure I followed:

- Make sure the I2C works and the GUI and connect properly by changing a couple setting and run the motor

- Load saved EEPROM

- click " write to EEPROM"

- disconnect USB

- power cycle the board

- plug the USB 

- hit "read register" -> and find the EEPROM was not written since the setting is not the one with saved EEPROM 


Not sure if anyone has seen the same issue.
As we have purchased 3 EVM and design one custom board, and all have the same issue
