I tested my chip cypd3125 by cy4531, and I could use PSoC programer to program/read firmware in my chip by SWD using MiniProg3. And then I put the cypd3125 in my demo power adapter, and SWD pins connect the typec pins to ensure I can connect it by typec line.  However I can't connect the cypd3125 by SWD(I use vbus pin to power),what's the difference between cy4531 and my demo power adapter? thanks.

Hi,

May I see your schematic to check the difference?

If you want to update firmware through CC Type-C interface, CYPD3135 with CC bootloader is a better option for your product.

Eddie
