UCD90120A: Having issue downloading firmware to UCD90120 using TI Digital Fusion software

Part Number: UCD90120A
Other Parts Discussed in Thread: UCD90120,

I am using USB-to GPIO firmware 1.0.11 and Fusion Digital Power Designer Version 7.3.1 - (Built on Wednesday May 6 2020) to download UCD90120 config file (.xml) to the UCD90120 power management IC.

However when I go open the Configuration window in Fusion Digital Power Designer Software and try to download the config file using Menu File> Import to Device, I get the following error at the last step. 

https://ticsc.service-now.com/sys_attachment.do?view=true&sys_id=e592a194db29189056e4d7b2f396190e

But when I try to download the config file using "Store to Flash" button , I get the following message with no error. But I don't trust this method, as it is inconsistent and it does not seem to flash to memory every time. 

https://ticsc.service-now.com/sys_attachment.do?view=true&sys_id=6d92a194db29189056e4d7b2f3961909

I prefer to use the first method but it is not working. Any idea what going on?

    Hello

    Are you using UCD90120 or UCD90120A? please be noted these are two different products. And the latest Fusion GUI has stopped support UCD90120.

    By the way, we can not review your attachment. could you repost the error message?

    Regards

    Hi Yihe,

    Thanks for your response.

    We are using UCD90120A ,  UCD90120ARGCT to be more exact.

    Here are the Image:

    Hello

    Both method are the same. you can adjust the delay based on the snapshot to fix the first method issue.

    Thanks! That did fix the issue.

    Although UCD and Fusion Digital software is a great tool. Detecting the IC from the Digital Fusion tool is a major pain, and 50/50 chance. I have to reset everything and retry multiple time. I have used UCD in all 3 generation of our products, and it is quite frustrating. Could you please relay this message to the development team so that they can make some improvement?

    One more issue. There is one board where I am sseing the following error. I have tried to download the firm multiple times still no luck any idea?

    Hello

    Thank you very much for the feedback. We would like to understand the case of failed to detect the device 50%.  Could. You please provide more details of design and how and when the problem occur? We will definitely help you solve this. If forum is not efficient, please contact your local TI representatives so that we can have more productive way.

    As for the particular error message , UCD90120A uses the same data flash for both user configuration and logging. But at any giving time, it can only do one thing. The message is to tell that  the flash is not ready for saving the configuration into flash. You can try it later.

    Regards
