USB EZ-PD™ Type-C Forum Discussions
Hi folks. We are unable to get the CYPD3125-based design to use MODE C or MODE E.
I am using CYPD3125. I use the EZ-PD Configuration Utility to restrict the supported modes to C or E (4-lane DP is the requirement).
I connect the CYPD3125 (as DFP) to a monitor via Type-C cable. The monitor responds to a "Discover Modes" message with support for modes C,D, and E.
After "Enter Mode", the CYPD3125 sends "DP Configure" asking for MODE D.
We require 4 lanes for DP (so MODE C or E), how can we get the CYPD3125 to configure for MODE C or MODE E?
Thank you!
Show LessI get a problem that update Fireware to CYPD3171 of CY4532-EVK mian borad:
First, I uesd EZ-PD Configuration Utility to update FW to CYPD3171 successfully, twice!
Second, third time to update CYPD3171 FW was failed;
Then, EZ-PD Configuration Utility only can find one device(CYPD 4126), can not find the device of CYPD3171!
I'm pretty sure the setting of jumpers is right (because I have update FW twice ).
I also use CY4500 analyzer to check if CYPD3171 is work or not, from the protocol data packet, CYPD 3171 is still work!
Show LessHello
It would be very helpful if you could get an answer as soon as possible.
Please tell me about the Source board that supports USB-PD using CYPD3196-24LDXS.
The connection destination is a smartphone or tablet, and the original plan was to connect only to Type C.
However, the specifications have changed and it is now connected to Micro USB.
(In this case, I want to exchange data without supplying power)
●5V line FET SW does not turn on with CC PU and PD alone (VBUS-P-CTRL does not output L)
The timing when the FET turns on is after the CC communication (negotiation) is completed.
Therefore, the FET does not turn on when connecting to the micro USB.
Is my understanding correct?
Best Regards

Show LessHi,
We've used HPIv2 Application Hardware Event (0x1B) to detect HPD plug and unplug events. MCU received these fine on Sink mode but now when using Source mode these events are not available. Curiously we do receive HPD IRQ event (EVT_TYPE: 3) even though HPIv2 specification says it's not used in Source mode. We do not receive HPD status update complete event (EVT_TYPE: 4) that is Source mode only event.
What is the recommend method to monitor hot plug status in Source mode? Use case is to know and report to end user wether cable is connected to a valid device.
Thanks!
Edit: clarified use case
Show LessHi
I'm looking for a version of the CCG3PA that it is using a resistor divider instead of the idac to control the VBUS voltage.
Do you have a document explaining me the solution with the resistor divider?
Are the PPS supported as well with this solution?
Thank you

Show LessHello,
I am stuck with two different problems with the configuration utility and can't update any firmware on the CYPD3171 chip because of them
The first one:
when choosing read from firmware file option (ctrl+shift+o) and choose the default "CYPD3171-24LQXQ_cla_config.cyacd" or any other ".cyacd" file, i get the error "Error: CYACD file does not contain configuration"
The second error:
When connecting CY4532 kit to program the CYPD chip and go through "Tools --> Firmware update" and select the "CYPD3171-24LQXQ_cla_config.cyacd" file the upload gets to 30% and then i get this error message:
PD contract established.
Restarting the target device
Re-negotiating PD contract after switching target reset
PD contract established.
Error: Invalid input file.
Error: Failed to read from file (C:\Users\hi\Desktop\CYPD3171-24LQXQ_cla_config.cyacd)
Device is in boot mode: Starting FLASH update operation
Error: The file/path provided does not appear to exist
Error: Failed to read from file ()
Device is in boot mode: Starting FLASH update operation
Error: Failed to find valid firmware file for update
Error: Flash update procedure failed
Error: DLL call returned error while flashing
and sometimes the error at displayed at 99% of the download process and the cypd3171 does not show up ( only 1 device is detected instead of 2 ) so then i have to replace the chip and try to program it again
Note : i replaced the chip correctly many times and the software detects 2 devices before software download
Power SDK Version 3.4
Configuration utility version 3.1
So in a nutshell: i can't open ".cyacd" files from the "read from firmware" option, and i can't update the cypd-3171 software as the download stops due to the mentioned error at 30%, or the download completes to 99% and then stops and the cypd chip doesn't get recognized after that

I have CY4531 kit an i did a board with CYPD3175-24LQXQ (ccg3pa) us a port controller for my usb. Now I have to program my port controller in my board.
So I want to ask if any one knows how i can do it, can i do it from CY4531 if yes how?
Any suggestion is welcome.
Thank you.
Show LessHi Cypress
We use cc communication equipment to request 20V/4.25A power supply. We verify the output voltage and current through the electronic loader. The test result is only 20V/4A (250mA less). But we change 0.01 current sense resister to 0.005, It can output power to 20V/4.25A .Please tell us how to debug the problem, thank you ! !
