USB EZ-PD Type-C

Anonymous
Not applicable

Hi,

I'm using CY4531 EZ-PD CCG3 EVK. The original firmware is in the installed directory, CYPD3125-40LQXI_notebook_one_1_0_3_516_0_0_0_nb.cyacd

Without the changing original firmware in the EVK, I've tested PD transaction with other boards and I found out this evaluation kit's PD revision is 2.0 not 3.0.

I've requested for the technical supports, and they says CY4531's default is PD revision 3.0. But it's not, it's working as PD revision 2.0

I want to change the working version as 3.0.

For that, I'd like to be guided to get a new firmware for this EVK which is working as PD revision3.0

Would you send me the link or newest firmware?

Thanks,

Yeonok

Hi Yeonok,

1. It might be possible that the other device being connected with the EVK is PD2.0, which will cause CCG3 to fall back to PD2.0

2. Please provide the complete cc log to debug more efficiently.

Rajath
