Hello,
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

Please provide us value of Ja , Jc , Jb , Tj parameter.

Hi

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.

Hi 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 ! !

Hi

I have a board with CCG3PA (CYPD3175-24LQXQ). Now i have to program it to use it as a port controller.

I was thinking to use the CY4532 to program it. I followed the user manual but still I can't do it. When i open EZ-PD Configuration Utility i can't see any port.

Any one can help me how to do it, or any sugestion?

Thank you

Hi am  looking for  any example in Power SDK or Host SDK  of implemnet  I2C  SCB  block  as   I2C  slave   usage byte level APIs

all examples  which  i found or  community support refer me to is master  

could  you please  refere me to slave i2c scb block in  usage byte level APIs   it  will  help me  reduce  size of  my application

how to configure different CCG3PA device address if master control multi-devices over I2C communication,, and hope to provide the detailed documents and specified  sample code related to  the aspects issues, it is not very clear as below snap picture, according to the document, seem the device register address is not configurable  due to only three fixed model, thank you!
