Hi,

There might be some problem in modified firmware that you have programmed. So PD contract is not getting established between the programmer and the CCG3PA.

If the hardware you are using is CYPD4532 EVK,

Please refer to Question: What should be done if the CCG3PA controller is not detected in the EZ-PD Configuration Utility? in the KBA Frequently Asked Questions on CY4532 CCG3PA Kit – KBA226613

Hi,

Please do clarify the following,

>> Are you trying to read/ Update configuration table from CY4532 EVK or some custom board?

>> Have you programmed any modified firmware to the board before getting this error?
