Hi,

If you already connect CYPD3125 to your PC as is mentioned in your description, then you can simply open EZ-PD configuration utility. You'll find CYPD3125 in your device list. I have an hardware example of connectting CCG4 to PC via I2C here:

Hi,

I'm sorry that's not possible for now because we do not have any plan to release the source code of EZ-PD Configuration Utility.

I'm sorry that I wasn't more clear. We do not have any plan to release the source code for updating firmware through I2C as well as any relating document. So your target to build your own program is basically impossible.

Hi Eddie_Z:

       If we complete the code by ourselves, can you provide some APIs or suggestions, such as how to make cypd3125 enter bootloader mode, and what commands can be updated after entering mode loader mode? Thnk you!
