1. May I know what you have been seen on your end when you cannot reply the previous threads (CYPD3125 )? Could you please screen shot to us to let us investigate the root cause of this?
2. CYPD3125 support 2 programming ways:
One: SWD with HEX file. This need wire VDDD,GND, XRES, SWD_CLK, SWD_DATA out. And then, it connect to miniProg3 . The software is PSoC Programmer. You could refer the link to get details information: (Programming EZ-PD CCG2, CCG3, and CCG4 Using PSoC Programmer and MiniProg3 - KBA96477 ).
The other, I2C bootloader with CYACD file, The concerned pin is
And you need a USB to serial chip (for example, CY7C65215 as CY4531 board). The software is Ez-PD configuration Utility. You could refer Ez-PD configuration Utility User Guide to see the details steps for firmware upgrade. (http://www.cypress.com/file/183686/download ).
Thanks for your quick reply.

In the previous discussion, I have seen only the action icon.
Remaining things can't able to see. ( Like, Helpful.... etc). So I created a new thread.
Thank you so much for coming back with details. Let's support you in this threads if your have further questions about CYPD3125 Hardware Configuration.
As per your suggestion, used Miniprog3 for programming via SWD interface and programming also succeed.
But Across VBUS getting milli volts only and even mosfet's are also not enabled, across VBUS_P_CTRL0/1 getting milli volts.
The MOSFET's are N-Type MOSFET.
Programmed CYPD3125-40LQXI_notebook firmware. Kindly advise to overcome this problem.
