Part Number: UCD9248
We designed a system with UCD9248 and tried to use Fusion Design Online PC Software with USB GPIO adapter.
The device itself comes with fabric hardcoded defaults (Status CMD 0x80 : => 0x24).
At the first start the device was recognized successfully, but autoconfiguration by Fusion with first simple Rail#1 required to proceed failed.
We used I2C SMB Debug to manually configure a PHASE_INFO with the 0xD2 0x01000000 command. After that the Software startup the
GUI as expected.
This autoconfiguration bug should be fixed, (if it is one).
In reply to David Banas:
Confirm that it is the bug in the GUI. It will be fixed in the next release. Apology for any inconvenient. Meanwhile, the work around is to use the low-level GUI tool (UCD3XXX/9XXX Device GUI Tool) to write the PHASE_INFO (0xD2) with 1 page configuration (value = 0x01000000): The tool can be launched from Start Menu -> All Programs -> Texas Instruments -> Fusion Digital Power Designer -> Device GUIs -> UCD3XXX/9XXX Device GUI, and then select SMBus/I2C tab; click on SMBus Debug link to open "SMBus/I2C/SAA tool. Make sure to enter the correct device address (see screenshot),
