Hi,

CYPD4531 and EZ-PD Configuration Utility do not support the way your want to flash your device.

Hi,

CYPD4531 has only one CCG3 without other chips like CYPD4532. I don't know how did you get the UFP-AMA in your EZ-PD Configuration Utility but Notebook in the target list should be CCG3.

Hi,

What is the cc controller of your power adapter?

If it's CCG3PA then you could use the mother board of CYPD4532 to update it firmware.
