Hi, Terry,

Are you using Fusion GUI tool or your own SMBus Tool to send the command? If you use your own tool, you will need to parse data and format the command per your SMBus Tool

Hi Anne,

These pictures were from Fusion GUI. In other words, I sent the command from CSV via Fusion GUI.

Hi Anne,

Please check the attach.

Data Flash Script.csv

Additional information: I can button store to RAM to NVM. But it cannot help us implement our system. My goal is help to program UCD device by own system from CSV file. I cannot use command which from CSV because it will encounter NANK.

Hi, Terry,

Can you send the project file (.xml) of the current device you try to import the .csv to? If you use Fusion GUI, click on File menu -> Save Project As....

How many devices you have on the system? What are they?

We try to duplicate the issue you are facing here.

Hi Anne,

Please check the .xml. UCD90320 @ PMBus Address 17d Project.xml

My system has only 1 device on SMbus.

Hi, Terry,

The device is write-protected (as shown in the below screenshot when open the project file you sent) => that's why device NACK on commands. Please unlock the device using the known password, then you can import the configuration to device.
