As I fail to use UCD9248 to produce the correct programed power. I write my design and download operation in detail. Hoping you can help solving the problem. Thank you.
1. Make a simple offline design
In the following picture, the red R icon is too difficult to get rid of, maybe it is impossible. If I make some change in the setting. I should press write to hardware button (although I do not connect the hardware with PC through TI USB Interface Adapter), otherwise the save button would not actually save the changes to the project file (.tifsp).
More R icons appear. Even I get rid some of them such as over current fault limit by setting its value, after save and reopen the project, it appears still not setted and R icons remains.
What is the relationship between these setting in the following figure and that in the above figure. Are they redundant?
These settings are applied.
After these setting, I save the file as temp.tifsp. Its zip file is attached here, please extract it, since I can not upload a .tifsp file.
2. I erase the UCD9248’s data flash to make it as from factory.
3. Download the firmware using .tifsp file.
I open Fusion Digital Power Designer in the online mode. The GUI tell me to download a default firmware to the device. I follow.
The default firmware is downloaded.
I download my firmware by importing system file
Error occurs during importing system file.
I find many parameters are correctly downloaded. But I do not know which parameter is not downloaded. I think there should be at least one because error occurs during importing.
The module information may not need to be downloaded.
4. 4. Monitoring
I think, after above steps, I should see output voltage, but I can not. I have also verified it by oscilloscope. In the following figure, Does the button turn on means to enable the PWM pulse?
