UCD9222: power-on waveforms are not monotonous

Part Number: UCD9222
Other Parts Discussed in Thread: TMS320C6678, , UCD7242

Dear expert,

My customer is evaluating UCD9222+UCD7242 power supply for TMS320C6678's CVDD and CVDD1.

When debugging UCD9222+UCD7242 power supply, they found
1. The power-on waveforms are not monotonous and form a ladder, and the attachments are test waveforms and configuration files;
2. When trying to modify the switching frequency on the Design page, the log prompts to modify the error, NACK. And the program on the configure page will crash. It is suspected that win10 is incompatible, the TI software is the latest version 7.3.1.

Please kindly share your suggestions, thanks.
